Cat ® Product Link™

  • Cat ® Product Link™ will support your business, and accurately convey information of the equipment to relevant personnel in a timely and effective manner for your better equipment management

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

  • 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

Structures

  • 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

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
