Product details


Dual path hydrostatic drive with electronic control technology



• Leverage Caterpillar technology and experience on TTT designing and production



• Single lever for speed changes, direction control, counter rotation, power-steering operation delivers higher efficiency.



• Counter-rotation and power-steering feature delivers excellent maneuverability on job sites.



• Counter rotation—Tracks counter rotate to provide best in class maneuverability.



• Power-steering —Machine maintains full power through steering to increase productivity.



Comfortable Operation



• Multi-function joystick allows for counter-rotation, powered turn and cruise control reduce operator’s working loading and improve the productivity.



• Pilot joystick control provides comfortable precise blade operation.



• Fuel level indicator is standard so that operator can know the instant fuel volume and charge it in time. 



Blade and implementation system



• SU blade combines the excellent penetration of the S blade and the high production capacity of the U blade.



• 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.



Undercarriageand brake system



• 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 efficiency 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.



Cooling system



• Standard cooling system meets -43°C ambient temperatures heat exchange requirementand +50°C high ambient cooling package is optional.



• Modular designed radiator, avoid the interaction easy to disassemble and reassemble.



•Hinged radiator louvered guard allows easy accessfor daily maintenance.



Maintenance



• Electronic Control Module (ECM) fault diagnosis system,automatic diagnosis of eight key parameters.



• Monitoring system provides three levels alarming for signals from different system,easily indicate the location or system the failures or defects from



• Small volume transmission oil requirement for hydrostatic system (40L only) with longer service interval (2000 hrs),reduces maintenance cost by 60%.



• Implement valve mounted outside of hydraulic tank provides easy access to check and service.
