  • Feature

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.


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 effi ciency and lower maintenance cost.
  • Durable final drive bearings and multiple wet disc brakes 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.
