SEM Product Advantage

Wheel Loader

  • The traction force of the whole machine is large, and the bucket is easy to penetrate into materials, saving fuel and improvingproductivity.
  • Faster Hydraulic cycle time and larger breakout force means high productivity.
  • The counter-shaft gearbox and heavy-duty axel are reliable and durable, while separated double-row bearing block implies easy replacement and high reliability.
  • High maximum speed delivers high productivity, comfortable operation with great features.
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.
 

Motor Grader

  • High Performance: Load sensing variable piston pump and specially designed PPPC valves provide superior control and better machine performance.
  • High Reliability: Specially designed SEM tandem axle, flanged large box section front frame, A-shape drawbar frame with box section, are designed to handle heavy duty applications providing excellent reliability and durability.
  • Easy Operation: Specially designed operating levers matching specially designed hydraulic system give operators outstanding "feel" .

Soil Compactor

  • High Reliability: The proven Caterpillar pod type vibration system matches the hydraulic components of world-renowned brands and the industry standard supporting power and transmission systems. This ensures the  reliability and durability of the whole machine.
  • High Performance: Highly-pressurized closed hydraulic system drives the pod-style vibratory system to create a smooth operational norm., The travel speed matches the vibratory frequency to provide excellent compaction performance and efficiency.
  • Easy Operation: Powershift gearing, hand throttle, and automatic engine speed adjustment for gearing controlled by the clutch pedal.
