Cat ® Product Link TM

• 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, 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

• ■ 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.

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.
