      Cat ® Product Link™

      Cat ® Product Link™ will support your business, and accurately convey information of the equipment to relevant personnel in a timely and effective manner for your better equipment management

      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

       

      Advantages

       

       

      Efficient: The electronically controlled hydrostatic drive system and multi functional joystick provide high levels of performance and maneuverability

       

      Comfortable Operation: The cabin is ergonomically designed for increased operator comfort and visibility. The advanced monitoring system tracks machine operating conditions and keeps the operator informed of all vital machines functions

       

      Reliable: The proven hydrostat design along with world class pump and motors provide a highly reliable tractor. The undercarriage components are designed for longer life versus the leading competitor

       

      Serviceability: The SEM tractors are designed for easy access to reduce overall maintenance time. The machines electronic control module allows for quick troubleshooting
