2 Harvesting heads - Log Max

LOG MAX, OVER 30 YEARS OF SERVINGTHE GLOBAL FORESTRY INDUSTRY

Over the years Log Max has become one of the most significant manufacturers of single grip harvesting heads. The Swedish forest industry is on the cutting edge of technology and equipment, this resulting in our product being sold around the world.The aim of everybody involved at Log Max, from the staff through to our partners and distributors, is to ensure that the professional loggers’ choice of Log Max is based on satisfaction and quality.

Therefore state-of-the-art quality and competence to induce high productivity combined with a concern for a long term environmental awareness is our mission statement.

The Log Max way to success

• Aproductoftechnicalexcellenceandperformance.• Thecompanyiswell-knownandwell-reputedinthe industry.• Well-experiencedtechnicalsupportandcustomercare.• ConcentratedworkwithISO/qualityassuranceinevery ongoing process.• Continuousstaffeducationregardingcommitmentand understandingofeachcustomer’sworkandrequirement for profitability.

Alltogether, this has made Log Max an established brand world wide.

Log Max - Harvesting heads 3


LOG MAX HEADS ARE DESIGNED FOR HEAVY USAGE AND DEPENDABILITY. WITH HIGH AND RELIABLE PERFORMANCE, LOG MAX WILL BOOST PRODUCTION UNDER ANY CONDITIONS.

Balanceandlowimpactfeeding

To facilitate harvesting, Log Max heads are designed to hang vertically when in “Tilt-Up”position,whichmakespositioningtostanding trees easier.

The roller arm and roller arm cylinder geometry increases leverage with increasing trunkdiameter.Thisgiveshigherrollerpressureonlargertrunks,whentractionisneeded, and promotes minimal crushing of fiber leading to higher quality timber.Thefeedrollersalwaysworkperpendicularto the tree, as opposed to using angled rollerarmstohelpcarrythetrunk.This limits frictionlossesandbarkscraping.

LogMaxpatentedknifecontrolwhichminimizes friction combined with the feed roller geometry and unique compound curve delimbingknifeprofileprovidesoutstandingstem coverage and increased log quality.

Durability and dependability

Insteadofcomplicatedsolutions,LogMaxharvesting heads use reliable standard machine components with long-term lubrication intervals, for example on bushings.

Allshaftsandpinsaremadeofnitrogenhardened steel and all bearing fittings are made of high tensile Swedish steel.

The frame design with short stress flows makesaLogMaxHeadlesssusceptibletometal fatigue. These features provide an extremely durable harvesting head with low weight, long life expectancy and low maintenance costs.

Productivity and profitability.

Sinceallmarketshavedifferentdesignrequirements, our product development and ability to adapt has given Log Max a significant advantage in many corners of the world.

LogMaxalwaysworkscloselywiththecustomers to provide the best possible solutions for every contractor’s needs.

Log Max lets you run your rubber tired or trackedmachinewiththebestandmostdependable headonthemarket.

Log Max heads are designed for installation on various types of carriers. Low weight is essential for the CTL-method using wheeled harvesters. This has resulted in Log Max being top of the range when comparing pulling force to weight ratio.

WHY ARE LOG MAX HEADS SO GOOD?A SIMPLE DESIGN CONSTANTLY IMPROVED


Weusetwotypesoffellinglinks,afullywelded Swedish steel closed box integrating two forged steel elements, the rotator fixture forthebestlinkagetothecraneandthebottom hinge connecting the frame.

Hydraulic System

The Log Max hydraulic system is engineered with simplicity and serviceability in mind, from the placement of the hydraulic components to the hose routing.

The hydraulic system is easily accessed for service through a tilt open cover, which requires no tools to open. Powerful feed roller motors provide high efficiency and low hydraulic losses.

Acaststeellinkisalsoavailableforthethoughestconditions.Thecastlinkismounted on all XT series heads, 6000 Twin and also on the latest eucalyptus head, the Log Max E6.

Measuring

The length measuring wheel is placed in the center of the frame between the rollers for accurate length measuring and high timber quality. The geometry of the roller arms is designed to increase the pressing force againstthetrunkwithincreasingoffsetfromthe center, i.e. the rollers always strive to center the tree over the measuring wheel.

Diameter measuring is calculated using sensors in both feed roller arms, which records diameter every 10 cm.

Cutting System

High performance saw hydraulics provide full flow to the fully enclosed saw motor for fast cutting,reducingtheriskofcrackformation.

Accumulation Kit

LogMaxhasdevelopedaAccumulationKitthat can be fitted as an option to Log Max heads. This allows the head to be used as a combination head - both as a conventional harvester as well as a multi-stemming head for thinning smallwood or in late brush cuttings.

The accumulation unit opens wider than the maximum head opening between rollers, whichallowstroublefreecollectingoftrunksevenwhenworkingwithcrookedtrees.

LOG MAX ACTIVE FRICTION CONTROLThenewgenerationfloatingtopknifefeaturingActiveFrictionControlactivelycontrols and adjusts the amount of friction between the log and the harvesting head’s frame. There is no need to go out and change the settings by adjusting the unit, everything is now set automatically. Low

friction is desired as it leads to lower fuel consumption and heat generation. There is the exception of when delimbing heavily branched trees with small diameter limbs a higherfrictionminimizestheriskofsimplybending them flat.

The harvester’s computer is the brain of theActiveFrictionControlandbasedonyour settings, the Log Max head behaves optimally depending on tree species and diameter. For example, a thinning of pine and birch can behave quite differently based on tree species.
