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.
