Machine specifications

 

Hydrostatic Drive System

  • Upgraded hydrostatic system not only leverages Caterpillar automatic, dual path, hydro-static drive with electronic control technology of the third generation TTT, but also increas-es efficiency and reliability
  • Adopt Rexroth German new generation drive pump to combine control valve, trackmotor, 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 filtratedprecision and cooling capability of hydraulic system, increasing reliability and reducingmaintenance 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

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 heatdissipation, easy access or maintenance

Maintenance

  • Electronic Control Module (ECM) fault diagnosis system,automatic diagnosis of eight key parameters
  • Monitoring system provides three levels of alarm,to indicate fault diagnosis
  • Hydrostatic system has longer service interval (2000 hrs),reduces maintenance time by 50%
  • Implement valve mounted outside of hydraulic tank provides easy access to check and service
