R422 Rammer Compactor with Honda GX100 Motor
The 422 Rammer is ideally suited for the compaction of granular, mixed and cohesive soils in confined areas. A mainstay in contractor and municipal fleets, the 422 offers highly a productive percussion rammer at less than 145 lbs. The contoured fuel tank provides the largest fuel capacity in its class and effectively baffles engine noise. Power is supplied by Honda engines.
- Elevated bellows placement for trench applications
- Patented polyethylene slide bearings provide minimal internal wear
- 11” ductile cast iron tamping shoe
- 4” and 6” trench shoes available for the 422

- Compaction Depth* – Up to 18 in.
- * Clean sand, optimum moisture. MBW recommends that lifts not exceed 12″ of granular soil, 9″ of cohesive soil.

MBW percussion systems are designed to fail a single slide bearing, locking up the system and preventing damage to other bearing surfaces, as well as bearings and seals in the rammer's gearbox. Because MBW percussion systems generate less internal friction, rammers operate more efficiently, consume less fuel, and deliver more compaction force for the purpose intended. When replacement is eventually called for, MBW slide bearings are replaced at low cost, returning percussion systems to original specification.
