Application & Product Usage



Caterpillar makes different models of SEM wheel loaders and track type tractors to be used for coal mining, grading, as well as construction of power plant and their production. During the construction process, operations such as flattening, backfilling, and compaction are involved. During the production phase, SEM machines are mainly used for coal processing, such as stock piling , paving and transportation.

SEM Product Advantage


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
