It’s the niggling things that can make Dubai in particular a frustrating place to exist. Here in Dubai, I’ve just resolved a thorny problem with the RTA about transfer-ring ownership of a car – not normally a problem, but this one didn’t have a functioning engine.

It only took a year. Elsewhere, my landlord has a dis-pute with the developer, with the upshot that through no fault of mine, I can’t use any of the building’s facili-ties, including the parking while the pair of them slug it out. On both occasions I’m met with the ever-so-help-ful response; ‘It’s your problem’. I’m sure you have sto-ries of your own.

Translated into the workplace, such small details where the precise, or at least alternative, way to pro-ceed is unclear leads to unplanned downtime, and therefore idle machinery, increased costs and oper-ators who should be operating. Usually this comes through no fault of the machine contractor, but from further up the chain – and usually because something wasn’t clear to somebody in the first place.

Dubai has been built on a culture of minimal reg-ulation – which is great – but cutting detail doesn’t

This shows that the document has been checked by a panel of boffins to be as clear possible, so that the intended audience will have no doubt at all as to what is happening as well as how, why and when. It’s a bit like PMV really, but without words like ‘pettifogging.’ We hope local ver-sions of these ‘marked’ documents both in English and Arabic will be available soon.

I’m pleased to say some business was done too, with one firm shifting no less than ten trucks to sever-al different customers.

Ten new trucks are handed over in what could be seen as a revival for the sector.

DEALS The dealer of Mercedes-Benz in Qatar has bagged a multi-million Qatari Riyals deal selling 10 Actros 4140B transit mixers to concrete batching firm Redco International in Doha, Qatar.

NBK Autos will supply the fleet of 8X4 concrete mixer trucks to the firm over the next few weeks. The machines have all been specified with 10 m3 Liebher drums, while the base vehicles all have six cylinder, 400hp engines and ABS brakes.

Safety chairman reacts over trenching fatality

Unlike this trench, an excavation in Ras Al Khamiah was not shored up.

SAFETY A recent incident which left a labourer dead has prompted safety watchdog Build Safe UAE to issue an alert highlighting the causes of what it views as a ‘horrendous accident’.

The accident happened on the 8th of March in Ras Al Khaimah when the shoring wall of a three-metre-deep excavation collapsed, burying a worker under tones sand, rocks and other debris. Police were alerted, but the 43-year-old victim, named as Jol Ahamed, was dead at the scene.

A photograph, taken by a local news reporter, showed that the rock pile, which had fallen in, was right next to the excavation. In addition, the snap showed that onlookers were standing right on the edge of the already partially collapsed hole.

BSU identified a number of failings that were apparent from the details available. The safety alert noted that excavations of this type should be boxed in, and that a simple risk assessment would have identified the danger.

Ashraf Kahoush, commercial vehicles’ sales manager at Mercedes-Benz, Qatar said: “We’ve enjoyed a longstanding relationship with Redco in Qatar, providing the company with the most advanced of commercial vehicles that add value to their operations and we’re very happy to be chosen as their reliable partner of choice.”

The Actros in it’s various forms is currently the best selling truck in Qatar, following the launch of the revised model back in 2008.

Additionally, the report noted that collapses of this type are a ‘very common issue’ and that regular briefings should be held with staff.

The organisation’s chair has reacted over the fatality. Grahame McCaig of Dutco Balfour Beatty said: “There is frankly speaking, no excuse for allowing people to enter and work under the conditions that were evident from the photograph of the accident scene and I would hope that the RAK Authorities are undertaking a full investigation of the circumstances surrounding the incident and will act accordingly.” He added that the management of the contracting company involved: “must be held accountable”.

McCaig also pointed out that the group has issued a number safety alerts for this type of incident over the past two years, saying that : “BSU has recognised trench collapse as a major cause of concern over the last two years.”

Zahid Chief: Saudi contractors want service INDUSTRY Saudi Arabia’s heavy equipment users are now less focused on getting the cheapest price and more concerned with after-sales service, according to Sheikh Fahad Y. Zahid, executive vice president of Zahid Tractor.

The company has responded, he says, by providing a service that goes beyond “just the wrench and oil filters.”

The company provides financing and aims to become a “partner” for its customers.

“We are very pro-active with our customers today.”

“They appreciate that [our] value is five to seven percent higher than the competition,” said Sheikh Fahad, speaking at the recent Saudi PMV Show in Jeddah. Sheikh Fahad (left) suggests the Saudi contractor is now more concerned with service.

“They know that their profit is in the project, so they finish the project, deliver it on time and make money – rather than the old days when they used to come in, squeeze the dealers and manufacturers and at the end of the day it was a loss-loss situation for everybody.”

Zahid, the long-term partner of CAT in Saudi Arabia, has recently added Bauer and a line of Egyptian-made buses to its portfolio.

TRAINING A two day ‘Quarry Academy’ for key management in Qatar was recently staged to discuss blasting and crushing solutions to meet demand for the large volume projects forecast for the Gulf Kingdom.

The ‘Academy’, jointly sponsored by local distributors Q-FAB and Boodai, was attended by almost 40 key senior management representing Qatari contractor, quarry operators and drill and blast companies.

“The ‘Academy’ was a continuous lecture-style presentation on the quarry process,” said Jukka Naapuri, General Manager, Sandvik Middle East FZE.

“As such, there were just two key papers – the first covering everything from opening the quarry up to feeding rock to the crushing plant . The second described in detail the

CONTRACTS The master developer of Dubai Investments Park (DIP) has announced the launch of the eighth and final phase of the sprawling industrial and residential complex.

Stretching across half a million M2, the launch is due to what Dubai Investments PJSC describes as ‘growing demand from companies across industry verticals.’

Meanwhile, Zahid Tractor launched a line of worker transport buses from Egyptian manufacturer Temsa Global. The range of full-size

people movers was launched at our Saudi PMV Show in March.

Upcoming projects such as, for example, the new Doha Port, specifying the movement of more than 50 million m3, have not been undertaken before in Qatar and are therefore expected to pose problems for local and international contractors alike.

Blasting, for example, in terms of the high volumes and how it can be handled by the authorities was just one key topic of discussion.

Crushing solutions involving the removal and processing high volumes of aggregates, sand and gravel including reuse on the project and stockpiling were also discussed in detail.

The ‘Academy’ is seen as a training programme focussing on the excavation process and mutual

interdependencies of its various sub processes. It emphasises optimisation of the entire excavation process, not simply patchwork measures aimed at individual areas of operation.

EMMISIONS Machine maker JCB has announced a line-up of Tier IV compliant diesel engines that don’t require a particulate filter or urea injection to meet the new European and US emission standard.

The company has invested around US $140 million in researching and developing a new combustion system for the new ‘Ecomax’ 4.4 litre engine, which in an industry first, dispenses for the need to have exhaust treatment.

The power unit is now undergoing in-field testing before going into production in 2012 to meet Tier IV interim/Stage 3B rules which are to become mandatory across Europe, the US and elsewhere within two years.

In the Middle East, a lack of urea-based exhaust fluid, and low grade, high sulphur diesel would render particulate filter and exhaust treatment technology largely useless.

Alan Tolley, the engine programme director at the UK-based firm said: “The expectation for the first part of the [new] legislation was that to achieve these really low particulate levels you needed to fit a diesel particulate

JCB Bauma line-upFirst on the list of Bauma entrants is a new line-up from JCB. Chief among these is a new Tier IV engine (see right), but the line-up also includes an improved quick hitch, a revised mini excavator, an all-new midi excavator and a really clever new micro telehandler, which is less than 3m long.

Sennebogen to launch 70-tonne craneAmong many other pre-Bauma announcements, Sennebogen have announced they will pull the wraps off a new 70-tonne telescopic crawler at the show. The new model will be the strongest in the firms line-up.

Terex AC1000 undergoing trialsElsewhere in Germany this month, the new Terex-Demag AC1000 has been undergoing trials. Exact details of the prototype have yet to be confirmed, but sources suggest it will eclipse the largest Liebherr LTM as the biggest wheeled crane in town. We’ll keep you posted.

RB Auctions go up in 2009For most it was an Annus Horribilis, but 2009 has proved to be one of the best on record for auction firm Ritchie Bros, who released figures in March. Bidder numbers were up, and total sales revenues increased in every market between 2-11%. In October, it sold its most expensive ever item, a 200-tonne unused Manitowoc crawler for US $1.275m Go figure.

filter, but when you look at that technology for our particular part of the market, namely mid-range construction equipment, we see there are some real disadvantages with that solution, in particular increased fuel consumption through increased back pressure to the engine.

Also, in many applications, load cycles are light and the DPF doesn’t self regenerate so you have to force it to do so and it needs fuel to do it.

“Our strategy therefore has been to meet Tier IV interim

emission standards without a filter, but also to achieve this without any exhaust after-treatment. We have focused our research and development efforts on a high efficiency combustion system; in other words we have made sure we don’t create the pollutants to start with rather than try and deal with them later. This approach also gives us very low fuel consumption levels.”

Tolley’s remarks came as the company was previewing a number of new items ahead of the Bauma machinery show.

Most powerful crane gets down to work CRANES One of the fastest and most powerful tower cranes on the market is working to its limit on an industrial project in Germany.

The giant red Wolff 1250B is pictured hoisting the numerous heavy parts needed to build the boiler support structure for a new power station in Wilhelmshaven.

The available working space around the supporting structure of the boiler is very constricted and as a result there is very little room for crawler or telescopic cranes.

capacity of 60 tonnes and a triple fall working speed of 63m/minute it is the most powerful and fastest luffing crane in its class.

Elsewhere on site, a smaller model 355B crane from the same maker is also toiling at conveying work for its living.

The smaller machine is located on a purpose-built crane track on the roof of the boiler supporting structure at a height of 110m. This enables the luffer to reach all sides of the boiler, and the adjacent assembly areas for the boiler house, without difficulty.

Thanks to compact dimensions however, the luffing jib tower crane is ideally suited for these conditions. “The tight space constraints necessitated that we pay particular attention to the footprint of the cranes,” said Mr. Löser, a project manager for lead contractor Donges Steeltec.

The design of this particular crane, with low component weights, enabled assembly times to be kept short. That isn’t to say that the crane is a lightweight. With a load moment of 1500 metre-tonnes, a maximum

Engines clean up their actWe take another look at the challenge meeting tough new emissions laws around much of the world, and the path followed by two makers

For most of us, a diesel engine is the big oily lump which occasionally needs an expensive rebuild, but generally gets on with the job. For an engineer, however the diesel motor is something of a paradox – on one hand it follows the same principals as the man from whom it takes its name. On the other, ever more demanding emissions rules from legislators, and efficiency needs form users mean that the

blueprints grow more technical each year.

However, engine companies have been up against their toughest challenge to date, as a new standard referred to as ‘Tier IV/Stage 3b’ comes in to force. This standard means that the amount of unburnt hydrocarbons, more commonly known as soot, must be brought down to the sort of level that is going to make the exhaust almost cleaner

going out, than the air being drawn in. Ironically, as we will see some of Rudolf Diesel’s original design elements are being reintroduced as the drive for more pressure, more power – and literally more ‘bang for your buck’ continues.

REDUCTION‘Selective catalytic reduction’ or SCR is a very technical way of getting a catalytic converter to work effectively.

To put what is a complex process into layman’s terms, a regular catylic converter, such as what you might find on a car, works by introducing a ‘catalyst’, usually platinum, to a chemical reaction, which renders the end product (in this case the exhaust gas) relatively harmless. SCR differs by using a liquid ‘reducing agent’ actually a fluid which is sprayed onto the catalyst. At one time ammonia was used , to kill the nitrous oxide

(NOx) by converting the output of industrial boilers into harmless diatomic nitrogen or water.

These days, a number of manufacturers have adapted this technology for use in roadgoing diesel engines, but by using an injection of a chemical based on the substance found in animal urine known as urea, the NOx is knocked down by up to 95% with no other toxic by products. There are a variety of different systems on the market at the moment, though as using urea injection is not mandated in the Middle East, few users take advantage.

One notable exception is the RTA in Dubai, who is using the stuff across its fleet in such quantities that it has been worthwhile for one manufacturer of AdBlue, as it is known, to establish a small factory in the emirate.

FORCED AIR One of the defining principles of Diesel’s original design was that compressed air was supplied with the fuel, enabling combustion at an atomic level. Improvements in injector technology have rendered this concept obsolete for about 100 years, but now the idea is coming back into vogue, as engine designers try to make every last drop burn completely.

PLANT DERVContrary to popular belief, running a vehicle on so-called biofuels is not automatically any cleaner, nor in many cases will manufacturers honour the warrantees of users

who have tried it. Properly refined though, there is no reason why it can’t be done. Indeed, Diesel himself tried refining peanut oil when no refined fuel was available with excellent results.

PERKINSSoon to be seen at this year’s Bauma show, the Peterborough-basedcompany will be showing off if it’s new Tier IV/Stage 3b line. Chief among these is the 1200 series, which is the firm’s range of 6-cylinder engines ranging in capacity between 4.4 and 7 litres. such as would commonly be found in earthmovers. The larger model is fitted with two turbochargers – one small, one large - which are mounted in series. The smaller first stage turbo accelerates quickly, giving response and torque at low speeds, while the larger second stage provides the high airflow required to provide the power density.All of the engines in the line-up meet the new smog rules by being fitted with a ‘diesel oxidation catalyst’ as well as a ‘particulate filter’. As the names suggest, the catalyst uses something (either platinum or palladium) to react with the exhaust and convert the soot and other matter into something more inert by means of simple oxidization. Meanwhile, the particulate filter literally filters out the harmful matter.

JCBUsing a different method of reaching the same target, machine maker JCB has announced a line-up of designed in-house Tier IV compliant diesel engines that don’t require a particulate filter or urea injection to meet the new European and US emission standard.The company has invested around US $140 million in researching and developing a new combustion system for the new ‘Ecomax’ 4.4 litre engine, which in an industry first, dispenses for the need to have exhaust treatment.The power unit is now undergoing in-field testing before going into production in 2012 to meet Tier IV interim/Stage 3B rules which are to become mandatory across Europe, the US and elsewhere within two years.

Eyes on the WestSheikh Fahad, Executive Vice President of Zahid Tractor suggests western KSA is ready for new technology and radical development

Of course there are shops lining the streets of downtown Jeddah, but mostly these are fulfilling a specific need or function. For example, the main

drag through town has a great number of car and parts dealers, interspersed with hardware stores and, somewhat bizarrely, about a dozen shops that stock French-style chandeliers.

Giant light fittings aside, there aren’t that many ‘lifestyle’ shops on the streets – stores that might be fun to visit, such as you might find in a mall, but there is one exception.

On the side of a busy street, small boys and their fathers press their noses up against the window of the shop, which is full of branded caps, sportswear, toys and otherrelated paraphernalia.

Interestingly, this shop doesn’t print the brand of some major football team, or even a self-congratulatory ‘swoosh’ or diagonal stripes. Instead, it sells stuf f with the brand of an industrial machinery manufacturer all over it – and the masses can’t get enough.

Sound unlikely? Not when you realize that the brand in question is Caterpillar, surely the most recognised marque of heavy equipment in the world.

CATERPILLARSo, it will come as no surprise that the family name most associated with Cat is nearly as well known as the brand itself. Zahid Tractor has been the sole dealer of the famous yellow machinery in the Kingdom for over forty years and is one of only two Cat dealers across the whole GCC. As you might expect, this makes the Zahid family a pretty big name in the Gulf, and none is bigger than Sheikh Fahad Y. Zahid, the executive vice president of the company.

The group has sold Cat machinery through good times and bad – from the near collapse of the Peoria factory in the early 1980s, through to the boom times of the mid 2000s.

Today of course, the machines are highly sophisticated, with complex electronics allow-ing the machines in most cases to be operat-ed with just a pair of joysticks, rather that the banks of levers and pedals of old. Saudi Arabia has generally been regarded as a price-sensi-tive country, but Sheikh Fahad believes that this is no longer the case: “When the electron-ic and laser guided systems were first fitted in the equipment about ten years ago, [Cater-pillar] was really looking at the western hem-isphere and maybe one or two far eastern countries for application.”

“The Saudi contractor today is very sophisticated and he is also on a

time frame” - Sheikh Fahad

SOPHISTICATED “But the Saudi contractor today is a very sophisticated contractor and he also is on a time frame” he stressed.

“He wants to get the job done in time, make his money and then move on to another project. We were able to success-fully demonstrate to the Saudi contractors how this new technology can assist him and make him more efficient providing him better quality, and that they don’t need the very top-notch operators who are hard to

find and to keep. We were able to intro-duce this new technology in Saudi Arabia.”

We noted that we’d seen a lot of very old machines working around the coun-try, a point which Zahid conceded: “Of course you do have these traditional con-tractors who like to ‘fly the plane by the seat of their pants’ and they would like to feel the gradient as they are working with the machine!” Expanding on this he added: “Competitors are, of course, very competitive, but they are not involved in the cut-throat pricing war as they used to be in the past. They have a healthy mar-gin, they know that their profit is in the project, so they finish the project, deliver it on time and make money – rather than the old days they used to come in and squeeze the dealers and manufacturers and at the end of the day it was a loss-loss situation for everybody. They weren’t get-ting the value.”

SERVICEKSA, and her Western Region in particular have been fascinating contractors for some time now, as it seems that when the downturn really began to bite, the Kingdom announced a number of new projects. In actual fact, the downturn hit private developers in much the same way as everywhere else, but the oft-written about,

and much needed boost in public spending to improve the roads, sea ports and to build a railway network around the area. Sheikh Fahad believes that the bulk of the work will come from one direction:

“The Western region has had its unfortu-nate share of flooding recently, and again it is a unique place vis-à-vis the central and eastern regions by having the mountains to our east and the Red Sea to the west, and a refinery to the south of us.”

“But our direction is heading in one direc-tion, which is north west. Over the years, as the population has increased tremendously, they [the people] have been trying to spread to areas that they can afford, whether they went to areas that they shouldn’t have [because of a flooding risk] or today are considered dan-ger areas, I think the latest announced gov-ernment plan in the master plan in Jeddah and the Western region is going to eradicate a lot of the problems that has caused these prob-lems to take place.”

Clearly, this will create demand for firms such as Zahid Tractor, a point which Sheikh

DEMAND IN WESTERN KSAThere is a huge scope for construction machinery across the Western Region. With almost a quater of the population living in delicately named ‘uinplanned settlements’ the plan is to rip these out, dam areas prone to plooding and embark on a massive construction programme, bringing the area into the modern age.

Zahid is quick to point out:“We see a phenomenal opportunity over

the talking shop was too far away from the world’s popu-lation centres, was falling down through years of over use and neglect, and anyway was resented by the majority of the Big Apple’s residents for being an expensive way to snarl up traffic on a regular basis. The professor argued that Dubai on the other hand, was perfect for the task – and the place he suggested was most perfect, was Down-town Burj Khalifa’s Business Bay.

Now, there is absolutely no suggestion that the UN would or has ever considered relocating to the Middle East, though the government did issue a state-ment saying that the body would be most welcome if it chose to come, but if it did, then we can see why the leather-patched lecturer specifically mentioned Business Bay. Put simply, it is where most of us would aspire to work, and the sweeping, mixed-use towers are ideally suited for large organizations who want their white-collar staff to work and live in the same place. Apart from the practical benefits, such a development is also very secure, but being a stone’s throw from the Dubai Mall and the rest of the city it will hardly feel like being confined to barracks.

SELF DEVELOPMENTThere are lots of these mixed-use projects in Business Bay, but one of the most noteworthy is the U-Bora towers. Being built by Korean firm Bando, the project consists of a large five-storey podi-um as well as a magnificent 56-sto-rey office tower, with a sail-like

curved side. Every single floor of this business tower was snapped up by a foreign hedge fund firm, off-plan, back in 2006, before a single bore was cast. As an aside, the term ‘Bando’ has a double meaning, as literal-ly translated it means ‘self devel-opment’.

The build was started back in 2007, initially with Simplex acting

as subcontractor. The subcontrac-tor left site in September 2008, leaving Bando both as developer and lead contractor. Like most of Dubai, the project was launched with massive optimism, and the residences sold out fast thanks to a payment scheme where inves-tors could put 20% down and pay

the remainder on handover. This lead the off-plan apartments to change hands at one stage for a reported AED3000 per square foot. The market has changed considerably now of course, but Bando are still confident that the market wants a building con-structed to the highest standards of design and finish. However, due in part to the market and

also because of the challeng-ing design, the build is running behind the originally project-ed completion date of Septem-ber 2009. That said, the project is progressing at a steady rate again and project director Jae Myung Park told us that the building would still be ready at the end of the year.

STEEL MOVING PMV visited on a special day in the project, as a huge pre-fab-ricated steel extrusion said to weigh as much as 270 tonnes is being fitted to the top of a cut-out in the residence block. This huge piece of metalwork spans 35 meters and consists of heavy trusses, beams and many types of pipe bracings.

There are always a great number of workers scurrying around the site, but now there is a number more, as specialists from metal maker Techno Steel, as well as the firms that provide the gear to climb it up the build-ing. “I’ve checked the records

WHAT IS HYDRAULIC JACKING?Jack-up construction, or ‘Strand Jacking’ is a method where concrete slabs and steelwork are lifted into position with computer-controlled hydraulic jacks. Because the multiple jacks can be moved in unison and with great precision, heavy structures can be assembled at ground level (with increased safety and reduced cost) and then lifted into position, rather than having to be built in the air. Traditional cranes and other lifting methods cannot provide this level of precision.

and today we have more than 1,500 people on site,” says the project coordinator Kim Myung Jin.

It would have just about been possible assemble the steel struc-ture in situ, but the amount of delay and costs to the project meant that alternatives need-ed to be looked at. Fortunately, moving extremely heavy metal is one thing specialists in Dubai are skilled at doing, so specialist heavy lift and post-tensioning firm VSL were brought in.

STRONGESTAfter the prefab section arrived on a low loader from the steel-work prefab yard in Jebel Ali, the first step was to remove it and lift it up the first eight storeys to the podium. First of all, the met-al had to get on to the podium. To do this, a giant crane has been

called in from rental firm Al Faris. This Liebherr LTM 1500-8.1 has a 56m luffing jib and 165t counter-weight, which provides an almost vertical boom setting. In sim-ple terms, this means that it can lift almost straight up, because of the unusual design of the mast. In fact, this particular crane is rated at 500 metric tonnes, making it one of the strongest mobile units working anywhere today.

The crane lifted the steel section up to the top of the podium, but it needed to go another 50 meters higher, and into a position that no crane on the ground could reach. Instead, the developer turned to the local branch of Swiss firm VSL to raise the girders using a series of hydraulic jacks to ‘climb’ the section into position. Pressure is put on each corner of the section with the pressurised units, and so

the whole frame inches its way up inside the arch.

LIFITNGVSL hydraulics operator Peter Lehe explained: “Each jack is capable of lifting 45 tonnes and we used a series of these to get it to the desired height. Luckily, there were no major problems with this lift and we only need to get one other lintel in place on this job.” David Gratteau, also of VSL add-ed: “On many jobs the time of day that we move the steel is a fac-tor. Often, people don’t realise the amount the steel expands during the day, and this can make a differ-ence.” He added that on this lift, precise measurements allowed for the variations though the day, which on a piece with this span can be several inches. Neverthe-

less, there must have been some nail-biting moments as a crowd of onlookers watch the steel creep into position.

Fortunately, after a tense twelve-hour session and as the sun set across the creek and in the shadow of the Burj, the sec-tion was finally in position, where it was bolted firmly in place while the sun set in the shadow of the Burj Khalifa.

Like the rest of this build, the pace was not lightening-fast, but the quality is very high. If the hedge company ever relinquish-es it’s grip on the business tower, some very lucky firms, or just pos-sibly the folks involved in a huge international non-governmental organization, will get to enjoy the view from this grade-A office eve-ry night.

Excavator attachmentsShovel heads, drum cutters, pile cutters and riddle buckets are all part of the excavator’s arsenal – but for which applications are these the weapons of choice?

We all know that excavators have buckets on the front. After all, that’s the point, right?

Well, yes, but there are several new technologies to increase the speed and reduce costs of excavating. Some you have probably heard of, if not actually used. Others might be less familiar.

A good place to start investigating different attachments for machines was German Gulf Engineering based in Sharjah. This firm has been going since 1974 and incredibly, at least one Atlas excavator from this date remains in service, though the majority of the fleet are now Hyundai machines of various weights.

“This is to be mounted on a thirty tonner,” said the firm’s plant hire manager, Mr. Menon said, indicating a large bucket with a quick hitch coupler, and a set of tungsten-tipped teeth, “This is for the normal excavation. Generally about 80 per cent of the work in the UAE is normal excavation, because the soil is very sandy.”

BUCKETSOf course, correct bucket selection also makes a big difference to the speed of a job, as well at the amount of diesel used.

Any bucket needs to be the correct one for the job. In any application, the bucket must be able to stand up to the huge break-out forces involved in it.

Buckets come in a wide variety of sized and shapes, but generally they can be put in to two categories: the smaller type for earthmoving, as seen on construction sites and larger buckets found in the quarrying industry. With extreme earthmoving projects ongoing, such as the anticipated Arabian Canal, these large rock buckets have fount their way onto construction sites. “For the canal, they need huge buckets” said Menon, gesturing towards a scoop roughly the size of a studio flat in Sharjah. “We have an even bigger one, too,” he added, as a giant 50-tonne Hyundai RC-500LC trundles into the yard with an even larger bucket.

However, bigger isn’t always better. When digging specific areas such as tight city workspaces, or narrow gulleys, it is obviously

better to have the correct bucket for the job as the amount of fuel saved by not having to double-handle work would be substantial.

DRUM CUTTERThe first device to catch our eye is a spiky-looking wheel attached to a machine that had just come back from hire. This is an Erkat drum cutter, and has been developed to eliminate the need for traditional rock breakers when trenching in hard stone. Users recon that the cutters nearly double

the output compared to traditional methods. Menon explained; “There are areas where the soil is too hard and the bucket just scratches, for this you need the drum cutter. It is very fast and safe.”

While drum cutting is only used on a handful of UAE sites at the moment, in other parts of the region it is very popular. “In Oman and Doha is very popular” he said. “We were the first company to use it here, and on several sites including The Waterfront where there is something not totally rock, not

totally limestone,” Apparently, the drum cutter ‘simply crunches through’ this type of high-carbide stone.

PILE CUTTERThe old method of demolishing unwant-ed foundation piles involved jackhammers, saws, and a whole lot of labour. Clearly, this would very quickly become a drain on resources should more than one pile need removing. “One of my specialities is pile cut-ting. We have cut over a million piles now” Memon said,

“We have a longitude cutter working in Dubai. This one cuts from the inside, outwards. Any pile over 1.4 metres we can’t crush with our machine. For that we use this and auger it from the inside, out. At the moment it is working at the Schumacher Tower in Business Bay.” Larger piles are necessary as buildings get heavier and taller. “At the moment, the standard here is piles 1.8 metres tall, but 2 metres will be common soon” he explained.

RIDDLE BUCKETSNot common in the UAE yet, these buckets with a meshed rear are invaluable for any application where soil or sand needs to be sorted from stone or rubble. They allow

brick, concrete, stone, vegetation or any other debris to be separated from soil, and the heavier duty, ribbed back models are suitable for sorting rock or concrete, prior to crushing or screening. While these buckets are not often seen here, a company new to the region, Fleco Attachments have brought these and others to the region. Andrew Morrison, a regional manager at the company said; “Riddle buckets are ideal for any applications where you want to move the debris, rather than the soil itself.” The gap between the riddle bars, known as ‘tines’ will depend on the nature of the stone and soil you wish to separate.” He added these were popular in the demolition industry in the ‘States, as well as closely related attachments such as skeletal rock buckets

GRAPPLESFor moving large boulders, or handling rub-ble on a demolition project, the tool of choice is a grapple, sometimes known as a grabber. Menon said; “This is for stone placing. We have a project coming up, where this grap-ple will be put on the end of a fifteen metre boom.” Used for placing stones, the grap-ple can also be found in the scrap handling

and demolition industries. A close relative of the grapple is the pulveriser, which is an evil looking jaw used in demolition, which can lit-erally ‘chew’ its way through brick. Modern developments now allow this attachment to also be used as a rebar cutter.

So now you’ve read the scoop, go and choose a bucket.

Whatever the application, the chances are that there will be an attachment to suit. ‘Riddle’ buckets are becoming increasingly popular.

PILE BREAKINGThe most basic method of breaking down piles is to either use hand held breakers or plant-mounted pneumatic breakers. While this method is perhaps the easiest to specify and takes no initial planning, it can produce unacceptable heath and safety risks and causes unnecessary damage particularly to small diameter piles if not very carefully controlled.

Specially designed pile breakers are available in a range of sizes and capability. Hydraulic pile breakers are both available for cast in situ and precast piles.

Skid-steer loadersThese small machines are evolving from simple mini-loaders into multi-function ‘tool carriers’ as modern compact engines and hydraulic drive systems become evermore efficient

Today, there are a multitude of skid-steers on building sites throughout the world. PMV managers are drawn to the usefulness of the compact machines on building sites. Although there is a choice regarding, size power, brand, and single or double arm lift, the most funda-mental decision for the plant manger to make is whether to buy wheeled or tracked model.

APPLICATIONIn certain cases, you have to go in to a tight area and the width and weight of the machine makes a difference, but that doesn’t often apply here (in the UAE) It is more about the payload and bucket capacity.

“Skid-steer loaders are a combination of workhorse and gopher at most jobsites,” says Jim Hughes, of Case CE. “In fact, they’re often the most productive and versatile machines on a jobsite. Throw in the fact a skid-steer loader is less expensive than other construction equipment and you’ve got a winning combination for many contractors.”

Hughes says he most often sees skid steers in these size classes used in material handling, digging, grading, clean up, site prep, scrap removal, truck loading and unloading. “Include an attachment such as a broom, power box rake, pallet forks, hammer or specialty bucket,” he adds, “and the applications are pretty much limitless.”

REQUIREMENTS Machine selection depends on many fac-tors, but the main concern is to define what the machine is going to be used for, and what sort of power is required. “The application is number one, what kind of payload capacity is the primary driver” said one expert. “Also if

Power is critical when considering the right skid-steer for any application. Bobcat still dominate the market here.

you are going to use it for work tools, depend-ing what kind of hydro-mechanical or hydro-electrical attachments you have, what kind of power they need, and will the machine be able to supply that?”

He added that working on tight sites can be a factor when choosing a machine. “In certain cases, you have to go in to a tight area and the width and weight of the machine makes a difference, but that doesn’t often apply here (in the UAE) It is more about the payload and bucket capacity.”

TRANSMISSION ”You may want to ask about a two-speed trans-mission if you need to drive long distances when the machine is unloaded from a trail-er,” says Gaby Rhayem, a regional manager

for Bobcat. “Using two-speed transmissions allow our skid-steer loaders to travel up to 12 mph in high speed, saving contractors valua-ble time.”

In addition, Rhayem says, Bobcat pioneered the development of four-wheel-steer skid steers, with independently articulating wheels. “

They’re excellent machines for applications where turf damage is a concern because the skidding motion is eliminated during turns, saving damage to the ground” he explained.

More skid-steer manufacturers are now placing a greater emphasis on cab ergonomics and offering a slate of cab comfort options. If you feel increased comfort levels equate to greater productivity, you can take your pick from deluxe, fully enclosed cabs with heat and air conditioning, stereo systems, ride control, suspension seats and low-effort servo controls.

CITY PROFILE

MANAMA, BAHRAINFor the most part, the tiny island of Bahrain is empty, but for a few square kilometers, the place is packed with peo-ple, machinery and extrava-gant building projects. Like the other GCC countries the tiny island spent much of the twen-tieth century diversifying away from pearling, fishing and the yolk of British rule, and into an oil-based economy.

Today sees the nation chang-ing again, as tax incentives make the country a haven for the off-shore banking industry, as well as having a developed con-struction industry and attrac-tions such as a fully-fledged F1 track. In fact, the importance of taking advantage of all revenue streams was underlined in the National Economic Vision 2030 plan, which was launched with great fanfare this time last year, just as the recession was start-ing to bite.

Unfortunately the downturn did hit Bahrain very hard, with one report putting the number of shelved projects since last Octo-ber at around 30%. This obvious-ly has had a drasic effect on both contractors and investors alike – most of whom are waiting for their money.

From our perspective as fleet managers, perhaps the most interesting industry in Bah-rainis the transport sector. While the other countries still moot the idea of 100% foreign ownership of companies, Bah-rain already does it, which has lead to the recent opening of a new industrial area, as well as a new seaport capable of handling the largest ships.

Steen Davidsen, manager of APM Terminals Bahrain said “Bahrain itself offers benefits for businesses, including a number of free trade agreements, a liber-al tax eegime and the allowance of forign ownership. Operating from the port makes clear eco-nomic sense and being 40% clos-er to the upper Gulf ports saves money for shipping lines.”

“Bahrain has invested billions of dollars to develop the best transport links in the region,

incorporating road, sea and air.”He added: “Our strategic loca-

tion can provide companies with road access to the booming economies in the Gulf, support-ed by the 25km causeway to Sau-di Arabia and the forthcoming Friendship Causeway to Qatar, which is scheduled for comple-tion in 2013.”

There is no railway on or near the island, so the freight needs to be moved by road, usually on

the back of a trailer pulled by a middle-aged truck head. There is evidence that the industry is modernising though, as the recently-formed Bahrain Logis-tics Zone, with large fleet oper-ators such as Danzas and CEVA starting operations.

TRAFFICCurrently, the only roadway on or off the island is the causeway into Saudi Arabia. This is often busy, as Saudi customs are noto-riously slow and most truck driv-ers will have horror stories about being stuck for many, many hours. Steven Gomes from Bon-aventure in Dharan noted that: “Trucks lined across the Saudi-Bahrain Causeway on both sides of the border present logistical nightmares for business, cus-tom authorities, not forgetting the endless waiting times for the trucking crew to get across.”

Gomes also observed that waiting in the stifling heat (tem-peratures have been known to hit 52 degrees) was having a bad effect on the heath of the truck

crews – something newcomers to the island should consider.

Of course, there is very lit-tle that can be done about there

being only one way out of the country, but is does make mov-ing trucks, machinery and peo-ple somewhat harder. It should be noted though, that the lot of the Bahrani-based trucker is generally better than that of his Saudi counterpart in terms of wage, living conditions and workers’ rights in general.

OIL AND GASIt would be churlish to write about Bahrain without mention-ing the rebounding energy sec-tor. Recently Dr Abdulhussain Mirza, the oil and gas affairs minister for Bahrain has said that the kingdom is planning to invest US$20 billion in the devel-opment of its hydrocarbons sec-tor. As US$5bn of this will be used to bring existing facilities up to date, it is likely that there will be work for heavy lift sub-contractors, as well as work for regular cranes and equipment.

“We have started in earnest the modernisation process in Bahrain over the last few years after Noga came into existence in 2005,” Dr Mirza is reported as saying in a recent interview.

“The process is now well and truly under way with offshore drilling for oil set to begin by the oil giant Occidental, in the very near future,” he added.

INFRASTRUCTUREBesides the road network, Bah-rain has reasonable infrastruc-ture, but it is clear that it is struggling with what the island’s ambitious plans demand. The power grid, for example could just barely cope with the load put on it over the summer. Works Minister Fahmi Al Jow-der recently that efforts were underway to limit the problem.

“People shouldn’t be blam-ing us for the cuts because the weather then reached 52C and I don’t believe any machine can withstand it,” he said, adding:

“Yes, we are trying to limit cuts, but it is impossible to stop them because anything may go wrong with the machines or the network.”

There were ambitious plans to develop the Tubli power plant, but the economic crisis has put this on hold for the time being at least.

OPERATORSThough the country prides itself on it’s human rights record, and that employees are allowed to unionise and are not sponsored by their employers, it must be noted that Bahrain lags behind the UAE in terms of employ-ee protection. Workers are still routinely carted about in open trucks, despite a ban on the practice. More seriously, cramped, overcrowded living quarters, with no proper cook-ing facilities have resulted in a number of horrific fires recently. Apart from this, some contrac-tors have been caught doing the most shocking HSE violations. One was found to be using work-ers as counterweights when proof loading an elevator. Lead contractors are advised to watch subcontractors carefully for this kind of practice.

The big, smoky traction engines provided a link to the future through the Industrial RevolutionATTRACTION OF TRACTION

Y ou can call them trac-tor heads or prime movers, but the main power unit for haul-ing heavy loads has

just one ancestor – and it had four legs. Slightly more recent-ly though, the Industrial Revolu-tion and its steamy glory meant that it was now possible to drive heavy loads over hill and dale.

In Great Britain, the term steam tractor is more usually applied to the smallest models of traction engine – typically those weighing seven tons or less – used for hauling small loads on public roads. Although known as light steam tractors, these engines are generally just smaller versions of the road locomotive.

They were popular in the timber trade in the UK, although variations were also designed for general light road haulage and showman’s use.

The most popular of these designs was probably the Garrett 4CD, which claimed to have four ‘compound horsepower’.

Designed for haulage of heavy loads on public highways, it was not uncommon for two or even three to be coupled together to allow heavier loads to be handled.

The characteristic features of these engines are very large rear driving wheels fitted with solid rubber tyres; three-speed gearing (most traction engine types have only two gears); rear suspension; and belly tanks to provide a

greater range between the stops needed to replenish water. All these features are to improve the ride and performance of the engine, which used to be used for journeys of hundreds of miles. Most road locomotives are fitted with a winch drum on the back axle. This can be used by removing the driving pins that secure the rear wheels, allowing the drive train to power the winch drum instead of the wheels.

A number of road locomotives are fitted with a crane boom on the front. The boom pivot is mounted on the front axle assembly, and a small winch is mounted on an extension to the smokebox in front of the chimney; the cable passing over a sheave at the top

of the boom arm. The winch is powered by bevel gears on a shaft driven directly from the engine, with some form of clutch providing control. These road locomotives can be used to load a trailer as well as to haul it to a new location. They are often referred to as ‘crane engines’.

A particularly distinctive form of road locomotive was the Showman’s engine. These were operated by travelling showmen both to tow fairground equipment and to power it when set up; either directly or by running a generator. These could be highly decorated and formed part of the spectacle of the fair. Some were fitted with a small crane that could be used when assembling the ride.

STEAMY These giant, self propelled

boilers put the industrial world on

wheels for the first time.
