The Second - hand SEM 522 Road Compaction Roller offers a winning combination of performance, safety, and reliability. Its optimized travel speed, synchronized with the vibration frequency, ensures efficient compaction while minimizing the number of passes required, saving both time and resources. The rear axle, equipped with a Limited Slip Differential, provides superior traction and maneuverability, allowing the roller to navigate challenging terrains with ease.
Safety features on the roller are top - notch. The new dashboard's 3 - stage alarm monitoring system provides real - time alerts for potential malfunctions or safety hazards. Automatic parking brakes engage promptly, preventing accidental movement, and the neutral start protection feature ensures the machine can only start in a safe gear position. The roller's reliability is further enhanced by its advanced vibration system with a sealed housing, protecting critical components from dust and debris, and the use of world - class piston pumps and motors in the hydraulic systems, which are known for their durability and long - term performance.

Applications of Used SEM 522 Compactor Roller
This versatile roller finds applications in numerous construction scenarios. In road building projects, it plays a crucial role in the initial soil compaction phase, laying a solid foundation for the road. It then moves on to compacting asphalt layers, ensuring a smooth and even surface finish. For industrial construction, such as the development of factories, warehouses, and logistics centers, the SEM 522 Compactor Roller compacts the ground to meet the load - bearing requirements of the structures.
In the realm of civil engineering, it's used for projects like canal banks, embankments, and dam construction, where proper compaction is vital for structural integrity. Urban development projects also rely on this roller for tasks like parking lot construction, sidewalk paving, and small - scale road repairs. Its ability to operate efficiently in confined spaces makes it an ideal choice for urban environments.
