SEM Product Usage
- Earth Moving
- Site Leveling
- Site Compacting
SEM Product Advantage
Wheel Loader
- The traction force of the whole machine is large, and the bucket is easy to shovel materials into, saving fuel consumption and improving production efficiency.
- Faster Hydraulic cycle time and larger breakout force means high productivity.
- The unique fixed-shaft gearbox and heavy-duty bridges are reliable and durable, while independent , double-row bearing shaft supports implies easy installation and high reliability.
- High maximum speed, comfortable operation.
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.
