  • Feature

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


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


Semi-Universal Blade

  • SU blade combines the excellent penetration of the S blade and the high production capacity of the U blade
  • Designed for superior load retention and penetration in tightly packed materials
  • L-shaped push arms bring the blade closer to the machine, providing excellent maneuverability, balance and blade penetration
  • Blades feature a strong box section design, made from high tensile strength steel to stand up to the most severe applications



  •  Undercarriage is provided by China industry expert ensures high reliability and resistance to wear
  • Carrier rollers track rollers and idle rollers are all maintenance free
  • Planetary final drive design delivers increased torque ratio for higher transmission efficiency and lower maintenance cost
  • Durable final drive bearings and multiple wet discbrakes provide reliability, reduce system heat and extend overall life



  • Machine structures are analyzed using Finite Element Analysis (FEA) and On Machine Stress Analysis (OMSA) to identify and protect high stress areas
  • Advanced structure welding technique, relieving welding stress.


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



  • 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
