Hydrostatic Drive System:
Upgraded hydrostatic system not only leverages Caterpillar automatic, dual path,hydrostatic drive with electronic control technology of the third generation TTT, but also increases efficiency and reliability.
■ Adopt Rexroth German new generation one case drive pump to combine control valve, track motor, simplified hose line design, continue to increase the reliability.
■ Caterpillar high pressure hose provides reliability and durability. Caterpillar control technology provides accurate control and high transmission efficiency.
■ Integrated the hydrostatic oil tank and implement hydraulic oil tank to improve filtrated precision and cooling capability of hydraulic system, increasing reliability and reducing maintenance cost.
■ Maintenance costs are reduced by 60% when compared competitors with torque converter and transmission and rear axle.
■ Counter rotation, power turn and infinitely variable speed save lots of time, increasing working efficiency.
Comfortable Operation:
■ Counter rotation—Tracks counter rotate to provide best in class maneuverability.
■ Powered turn—Machine maintains full power through turns to increase productivity.
■ Cruise control—Operators can retain previous speed settings which makes operation easily.
■ Multi-function joystick allows for counter-rotation, powered turn and cruise control.
■ Pilot joystick control provides comfortable precise blade operation.
Modular Radiator:
■ New advanced cooling system designed to meet -40°C to +50°C ambient temperatures capability.
■ Modular designed radiator, easy to maintain remove and repair.
■ Radiator grill provides better heat dissipation, easy access for maintenance.
