The R422 & R442 Series Rammers are ideally suited for the compaction of granular, mixed and cohesive soils in confined areas. A mainstay in contractor and municipal fleets, the R422 & R442 offer highly productive percussion rammers at less than 145 or 150 lbs. respectively. The contoured fuel tank provides the largest fuel capacity in its class and effectively baffles engine noise. Power is supplied by Honda engines.

SMART RAMMER SERIES The Smartest Rammers in the industry, this MBW line is equipped with integral tachometers and hour meters that indicate when maximum operational performance is being reached and when maintenance intervals are needed. The result is higher productivity and increased service life. Weighs between 158-177 lbs. (72-80 kg). Models R482R and R483R are recommended for altitude above 4000 ft. RAMMER SPECIFICATIONS Published lift capacity reflects ideal conditions (clean sand, optimum moisture). Good compaction practice restricts lift depth to a maximum of 12 inches for granular soils,...

RAMMER PERFORMANCE HIGH PERFORMANCE PERCUSSION RAMMERS MBW approaches rammer development aggressively. We attack high maintenance issues usually associated with this product type. The MBW delivery system is the lowest friction, heat, and maintenance percussion unit in the industry. Less friction, heat, and wear in the delivery system translates into lower continuous horsepower demands to keep the rammer running. That means fewer engine problems and longer engine life. Bellows failures are reduced by as much as 90% with MBW’s 4-ply, steel reinforced, vulcanized rubber bellows. MBW addresses maintenance...
