It is a double steel wheel vibratory roller produced by Ammann Company, which is suitable for small and medium-sized asphalt operation sites. Known for its excellent mobility and flexibility, it can perform compaction operations in different applications close to walls and curbs. It has a rigid frame and two smooth steel vibrating drums, both statically driven by hydraulic pressure and equipped with vibration function. The working principle is to increase the compaction effect through vibration, which is suitable for the construction of local roads, bicycle lanes, parking lots and garage lanes. The design allows the machine to work in a compact space. Its compact size and good mobility make it an ideal choice for small construction sites.
