SEM Track Type Tractor

Dual path hydrostatic drive with electronic control technology • Leverage Caterpillar technology and experience on TTT designing and production • Single lever for speed changes,Website:, 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.
