SEM 522F Compactor

More Efficient

• Shangchai engine meets China Non-Road Stage IV emission requirements, delivering lower fuel consumption, more powerful performance, energy saving and environmental protection.

• Caterpillar pod-type vibration system adjusts vibration amplitude by changing the center of gravity of the sealed movable steel balls. With no impact vibration structure, it starts vibration smoothly, switches amplitude gently, and provides flexible vibration start for smoother pavement compaction.

• Dual amplitude and dual frequency vibration system has been fully optimized and upgraded with increased frequency and exciting force for more outstanding compaction efficiency.

• Full series adopts hydrostatic transmission with infinitely variable speed, providing smooth and stable transmission and shock-free starting. Combined with the pod-type vibration structure, it enhances compaction quality.

• Optional density gauge, intake air preheater, and sheep's foot roller configurations are available to suit a wider range of working conditions and improve construction efficiency.

More Comfortable

• Three-stage vibration damping system, spacious cab with suspended knitted seat, optimally arranged air conditioning and multi-directional vents maximize operator comfort.

• Front-to-back adjustable instrument console with multi-function dashboard featuring three-level alarm meets ergonomic requirements and enhances the driving experience.

• Standard LED lights improve visibility and safety for nighttime operations, with better adaptability to working conditions.

• New control lever integrates direction change and vibration start/stop functions for simple operation.

More Reliable

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

• Modular cooling system cools coolant, hydraulic oil, and intercooler simultaneously. The overall installation uses floating vibration-damping pads to ensure stability under rough working conditions.

• Additional wheel-end brakes prevent brake failure of the central braking system in case of single-side wheel slip or axle shaft failure, providing greater safety in harsh working conditions.

Easy Maintenance

· New Stage IV family-style exterior with molded engine hood featuring rear-opening design that opens at a wide angle, making all service points easily accessible.

· Hydrostatic transmission without gearbox eliminates maintenance of the gearbox and clutch, making servicing more convenient.

· Engine oil pan drain is separately routed for easy oil changes.

· Fully sealed eccentric block with flexible vibration start technology effectively reduces impact loads, extends the life of bearings and hydraulic components, and requires no maintenance within 1,000 hours, reducing user maintenance and usage costs.

· Standard CAT® (Caterpillar) Vision Link telematics system enables remote machine location tracking and operational hours checking, facilitating unified fleet management for customers. Reference values: 1000.
