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
