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.
