Wheel Loader

  • Caterpillar has its own U-shaped arms and U-shaped buckets. The  link rod goes deep into the bucket, which moves back the center of gravity of the machine, making the whole machine more stable.
  • SEM wheel loaders can use second gear directly, which make e bucket insert materials easier and faster.
  • Performances series bucket can load 10%-15% more in the same condition which improves productivity 
  • A shorter hydraulic cycle time which leads  higher efficiency.
  • Caterpillar owned counter-shaft power shift transmission, a reliable axle and an separated , double-row bearing block, enable easy replacement and high reliability
  • Central main hinge design  with a large spread hitch, enable convenient maintenance, and excellent torsion resistance.
  • The front tires and rear tires make the same track when turning, which reduces tire wears and makes fuel consumption lower.

Track Type Tractor

  • High Productivity: Inherited from the mature hydrostatic transmission technology of Caterpillar track type tractors, the operating efficiency is as high as 30% year on year. 
  • Comfortable Operation: More comfortable operation with a large space canopy and good maneuverability in addition to a multi-functional electrical lever.
  • High Reliability: More reliable core components with world class pump and motor. Reinforced structures checked by FEA.
  • Low Operation Cost: Good serviceability and low maintenance cost without converter, transmission
