Features

         Hydrostatic Drive System

• The upgraded hydrostatic system not only leverages Cater automatic, dual path, hydro-static drive with electronic control technology of the third generation TTT but also increases efficiency and reliability
• Adopt Rexroth German new generation drive pump to combine control valve, track motor, simplified hose line design, continue to increase the reliability
• High-pressure hose provides reliability and durability. Cater ontrol technology provides accurate control and high transmission efficiency
• Integrated the hydrostatic oil tank and implement a hydraulic oil tank to improve filtrated precision and cooling capability of the hydraulic system, increasing reliability and reducing maintenance cost
• Maintenance costs are reduced by 60% when compared to competitors with torque converters 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

• The 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 disc brakes provide reliability, reduce system heat and extend the 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 heat dissipation, easy access or maintenance

  Maintenance

• Electronic Control Module (ECM) fault diagnosis system, automatic diagnosis of eight key parameters
• The monitoring system provides three levels of alarm, to indicate fault diagnosis
• The hydrostatic system has a longer service interval (2000 hrs), reduces maintenance time by 50%
• Implement valve mounted outside of hydraulic tank provides easy access to check and service
