Trelleborg presents a new step in Solid Tire Technology

CDM Technology

Elite XP: comparison between unloaded and loaded conditions

The rapid evolution of modern material handling equipment, the increase in lifting capacity, the use of powerful engines resulting in higher torques and stress is creating a major wind of change in the requirements for solid tires. This has led the industry to develop new sizes and solutions.

Trelleborg, a leader in the field of design and production of rubber resilients and press-on solid tires, has decided to take action and respond to this market trend through the technological leadership of its R&D and Technical centers. The result of new design concepts (named C.D.M.) is a new range of resilient tires called ELITE XP, born under the hystorical Bergougnan brand. Elite XP is a premium quality 3-stage tire designed to meet requirements of all applications, up to the heaviest duty.

The new range fully complies with ETRTO standards and is of course an OEM approved product through extensive field testing on various types of handling equipment, industrial trailers, excavators, etc.Elite XP comes in standard and in LOC mounting versions, for the best productivity of people committed to deliver reliable on time service to the industry.

An important step for Trelleborg, a Total Evolution for Solid Tire technology... Join us in this galaxy ofinnovation.

The Trelleborg Wheel Systems R&D department, an excellence center for the development of new tire solutions used in Agriculture and Industrial/Material handling sectors, has developed the new Elite XP with state of the art technology. In close cooperation with important laboratories and universities, new solutions have also been developed and applied.

The concept of controlling the internal deformation of tires both under load and in variable speed and acceleration conditions is one of the keys to success for the next generation of tires.

Trelleborg’s Controlled Deformation Matrix technology links the results of finite elements analysis applied on rubber based products with the XP Design System for crown and sidewall area definition.

A number of parameters have been selected, field-acquired, analysed and then correlated with Tire Design and Indoor tests allowing for controlled tuning of tire performances.

Elite XP Total Evolution

Efforts of Trelleborg’s R&D department have been strongly focused on how to optimize energy consumption linked to the use of Fork-lift trucks. In modern industry, reducing fuelling needs means both a saving in terms of money (fuel) and increased availability time of equipment.

Availability is a measure of efficiency for any investment in equipment: it can be defined as the number of hours worked by the machine divided by the total number of working hours.Especially for electrical Forklift trucks, where battery recharching time is a loss of productivity, reducing energy consumption brings great benefit and grants intensive usage of your investment.It’s not without reason that FLT manufacturers are continuosly investing in technology to reduce more and more the causes for (internal) energy loss (combustion, rotating parts, friction, batteries etc).

Up to 15% more life 13% higher energy efficiencyToday material handling equipment represents an investment for any company producing or trading goods. The perceived value of this investment can be greatly affected by the choice of tires fitted on these machines.Tires are made of rubber, a material that naturally shows a certain degree of wear during operations.

Trelleborg has managed to reduce this wear through construction design and new rubber compound recipes: ELITE XP today brings up to 15% more lifetime to your investment.Today ELITE XP standard black compound, a totally new development in the field of Polymer technology, has more wear and chemical resistance than ever.

20% More rubber- Elite XP tread pattern ensures the maxi-mum contact area (FOOTPRINT) between the tire and the ground - picture 1

- Elite XP shows the highest NET AREA, i.e. amount of rubber permanently in contact with soil - chart 1

- The higher the contact area, the lower is the specific pressure, this means:

1. less stress on the tire (preventing uneven wear phenomenons and possible early failure)

2. less aggressiveness on pavements of modern logistics sites

- Last but not least the squarer footprint ensures better stability

10% More tread depth - More tread depth allowing tire consump-tion to its maximum ensuring a longer lifetime

- Careful design of void area between lugs in order to minimize distortion of blocks and increase overall stiffness of tire and tread

- Special wear indicators show at any time the level of consumption and give an esti-mation of remaining tire life - picture 2

15% Less heat build up- Deformation control under any working condition cuts down heat build-up by up to 15% - chart 2 - This reduces the well known risk of tire failures and the need for careful driving.

- With Elite XP operating speed and carrying hauls are higher

- Thermo-camera analysis in field testing - picture 3 - proves that Elite XP is really cool!The best result against any competitor’s tire.

Energy efficient- Elite XP shows up to 13% better energy efficiency compared to competition tires in terms of Rolling Resistance coefficient (the typical index used for resilient tires) - chart 3

- This can result in savings of electrical energy (for ITA class 1 equipment), gas and diesel (for ITA class 4&5 machines)

Better equipment performancesElite XP also offers following improved machine performances :

- higher maximum speed- higher acceleration- benefit from reduced tire deformation

and lower friction

Total qualityEnergy Efficiency is obtained through the combination of new rubber compounds plus tire construction optimization

- Elite XP rubber compound is of the highest quality degree to cut down effect of hysteresis and plastic deformations, avoiding loss of energy when the tire is deforming - chart 4

- Elite XP raw materials are sourced directly from manufacturers and supplies are under the control of the Trelleborg Group to ensure production consistency

- the 3 stage structure of Elite XP, the distribution of the different layers and the shape of the tire are optimized by means of CDM technology for controlled deformation.

Elite XP Total Evolution

The main target for a resilient tire fitted on industrial equipment is to run problem free as long as possible and ensure safe operations.

Especially in sharp turns, hard braking or sudden change of direction, it is vital to keep the Fork-Lift truck as stable as possible in order to avoid displacement or, even worse, loss of the carried load.

This both to preserve goods and not to cause accidents involving human operators.

One of the main Elite XP features is that it benefits from a change in design approach. Together with standard criteria applied in the sector of Resilient tires for many years, Trelleborg R&D has introduced new concepts derived from parallel sectors such as Truck, Light Industrial Vehicles and MPT (Multi Purpose Tires).

Elite XP is not only the perfect tire for the end-user but also for people providing service to the industry: Elite XP is conceived as an «assembly unit», meaning it’s compatible with rims and wheels of any manufacturer respecting the ETRTO recommendations. Furthermore Elite XP is anticipating the most severe prescriptions in terms of Environmental Protection coming from the European Union Legislation.

That’s why Elite XP offers all the following features.

20% better stability under any working condition

New design concepts

76

Optimal lateral stability- During extensive lab and field tests, TWS has measured all parameters related to LATERAL STIFFNESS and road holding after unexpected steering (LANE CHANGE)

- In every condition both steering and load tires have been analysed

- Results show up to 20% better performance compared to the current market offer chart 5 and 6

Why take any risk then?

Extra load stability- Elite XP large footprint and higher contact area is a further guarantee for good stability

- Whenever sudden events such as hard braking, hits or skidding endanger the stability of the transported load, it is proven that a large support area is the best way to prevent drop of goods and increase people’s safety

- Elite XP features a high rim compression factor for firm fitment on wheels

Higher damping capacity- Elite XP extra stability is also related to its damping capacity

- Trelleborg’s new range offers better absorption (up to 10% over competition) of hits and vibrations caused by impact with bumps and holes - chart 7

- Elite XP’s control of deformations means also less time required to come back to normal running

Total tread traction- high traction both in indoor and outdoor applications due to its aggressive lug design

- maximum grip both on dry and wet surfaces with self-draining grooves

Noise control- Elite XP integrates a truck technology solution to reduce noise normally generated by the impact of the tread surface on the ground

- Elite XP tires can reduce tire related noise generation by up to 8% - chart 8

- Better compliance with health and safety standards for indoor working environments

Easy to work with- Mounting and Dismounting of the XP range is tested and approved by Trelleborg partners worldwide

- maximum compatibility with rims of the main wheel manufacturers

- high rim compression factor for firm fitment on wheels

Care for environmentThe new Elite XP is made of rubber compounds which are “Oil Free”.

This anticipates the prescriptions of EU Directive 2005/43/EC article 3 (2) coming from the European Commission. In this document it is decided that starting 01.01.2010 all polycyclic aromatic oils (plastifizers) have to be eliminated from industrial processes while Benzo[a]pyrene has to be used with a maximum of 1 ppm.

Elite XP: more attention to people, more attention to our future!
