Wheel Loader - Kelly Tractor

Hydraulic SystemNew modular system provides improved efficiency, low-effort controls and easy operation.Modular hydraulic system designed by ■ exceptional backdrag performance■ very fast loader cycle times; preserves your initial investment andCaterpillar provides low-effortoperation and greater control:due to a large tilt cylinder and newcheck valves;■ separate steering and implementpumps improve machine response;■ hydraulic system is virtually driftfree.■ load-sensing steering gives priority tothe steering system on demand,making more power available forrimpull, breakout and lift forces;Modular hydraulic control valves add anew dimension of versatility that greatlysimplifies and lowers overall cost of■ system is designed to manage use ofengine power and lower fuelconsumption;reconfiguring the machine for additionalfunctions.■ load-sensing implement hydraulicsprovide exceptional second gearhydraulic-to-rimpull match for betterperformance in tough materials;The standard 924Gz with pin-onimplement comes equipped with a twosectioncontrol valve for lift and tiltfunctions. If new applications place■ simultaneous lift and tilt functionshelp improve productivity;additional hydraulic requirements on themachine, such as adding a Quick■ velocity modulation of lift and tiltfunctions ... the further you pull orpush the lever, the faster the function;Coupler or powered attachments, youcan simply stack additional valvesections (totalling up to four) on the■ low-effort, single-lever implementcontrol;existing ones. There is no need to scrapvalves or change hydraulic lines. Thislowers the cost of machine upgrades.The control valves now featureconvenient ground-level access foreasier modifications to the system.Ride Control Option provides acomfortable ride at all speeds. Thesystem operates automatically or can beturned off with a switch at the operatorstation. The system uses a nitrogen oilaccumulator in the hydraulic lift circuitthat acts like a shock absorber for theloader linkage and bucket. The reactionto movement over rough ground isdampened, reducing fore and aft pitch.Other features include:■ compatibility with Cat biodegradablehydraulic oil;■ pressure taps allow quick diagnosis ofthe whole hydraulic system;■ Caterpillar XT hose & couplingsprovide rugged, reliable performancewith significantly reduced risk ofleaks and blown lines.6
