Opting for the secondhand SEM 522 Road Roller means getting high - performance equipment at a fraction of the cost of a new one. Its advanced propel system reduces heat buildup during operation, extending the lifespan of internal components and reducing maintenance costs.
Safety features are integrated throughout the design. The 3 - stage alarm monitoring system on the dashboard promptly warns operators of potential mechanical failures, overheating, or abnormal vibrations. The automatic parking brake engages immediately when the engine stops, preventing accidental movement on slopes. The roller's reliability is further enhanced by its sealed vibration system housing, which keeps out dust and moisture, and the high - quality piston pumps and motors that ensure stable hydraulic performance.

The used SEM 522 Compaction Equipment is widely applicable across multiple construction fields. In highway construction, it compacts the roadbed, stabilizes the crushed stone base layer, and conducts the final compaction of the asphalt pavement, ensuring that the road has excellent load-bearing capacity and durability. For the construction of industrial parks, it can efficiently compact large areas of land, laying a solid foundation for the construction of factory buildings and infrastructure. In municipal engineering projects, such as the construction of bicycle lanes and the renovation of old streets, its compact and flexible features enable it to play a crucial role in limited spaces and ensure the quality of the project.
