SEM 520F Compactor

Higher Efficiency

• The Shangchai engine meets China's National Stage IV emission requirements, offering lower fuel consumption, more powerful performance, energy savings, and environmental friendliness.

• Caterpillar pod-type vibration system achieves amplitude adjustment by altering the position of the center of gravity of sealed movable steel balls. With no impact vibration structure, it provides smooth start-up, gentle amplitude switching, and flexible vibration initiation, resulting in a smoother compacted surface.

• The dual-amplitude, dual-frequency vibration system has been comprehensively optimized and upgraded, with increased frequency and centrifugal force for more outstanding compaction efficiency.

• The full series adopts hydrostatic transmission with infinitely variable speeds, delivering smooth and steady power transfer and jerk-free starting. Combined with the pod-type vibration structure, it enhances compaction results.

• Optional density gauges, air intake preheating, and sheep's foot rollers are available to adapt to various working conditions and improve construction efficiency.

Greater Comfort

• A three-stage vibration isolation system, a spacious cab with a suspended knitted seat, and an optimized air conditioning layout with multi-directional vents maximize operator comfort.

• The front-to-back adjustable instrument panel and multi-function dashboard with three-level alarms meet ergonomic requirements, enhancing the driving experience.

• Standard LED lights improve visibility and safety during night operations, with better adaptability to various conditions.

• The new joystick integrates direction control and vibration start/stop functions for simple operation.

Enhanced Reliability

• The closed-loop hydraulic system uses world-renowned brand hydraulic components, effectively improving hydraulic transmission efficiency and easily handling various working conditions.

• The modular cooling system dissipates heat from coolant, hydraulic oil, and the intercooler simultaneously. The entire assembly uses floating vibration-damping pads to ensure stability under rough conditions.

• Additional wheel-end brakes prevent brake failure in the central braking system during single-wheel slippage or axle shaft faults, enhancing safety in harsh conditions.

Easy Maintenance

• The new Stage IV family-style exterior features a molded engine hood with a rear-opening design that opens at a wide angle, making all service points easily accessible.

• With hydrostatic transmission and no gearbox, maintenance of the gearbox and clutch is eliminated, making servicing more convenient.

• The engine oil pan drain is independently routed for easy oil changes.

• The fully sealed eccentric weights and flexible vibration technology effectively reduce impact loads, extend the life of bearings and hydraulic components, and require no maintenance within 1,000 hours, lowering user maintenance and operating costs.

• The standard CAT® (Caterpillar) VisionLink® system provides remote machine location and operating hours access, facilitating unified fleet management for customers. Reference values: 1000.
