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 stacking, paving and transportation.

SEM Product Usage

  • Truck Loading
  • Stacking
  • Feeding
  • Mixing
  • Paving

SEM Product Advantage

Wheel Loader

  • Caterpillar has its own U-shaped arms and U-shaped buckets. The pull 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 be operated in second gear  making it easy to insert materials and faster.
  • A large bucket capacity enables a high load, leading to shorter hydraulic cycle time and higher efficiency.
  • A shorter hydraulic cycle time equals higher efficiency.
  • Caterpillar owned fixed-shaft power shift transmission, a reliable drive axleand an independent, double-row bearing shaft support, enable easy installment and high reliability
  • Central hinge design and a large distance between the pull plates, enable convenient maintenance, and excellent torsion resistance.
  • The front tires and rear tires make the same rut when turning, which reduces tire wear and fuel consumption

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
