Product Feature

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

  • Hydrostatic drive with electronic control technology

  •  Maintenance costs are reduced by 60% when compared competitors with torque converter and transmission design.

  •  Counter-rotation and power turn feature delivers exc maneuverability on job sites.

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 a world class supplier 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.

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 -43°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.

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.
