MBW R422 Trench Rammer

MBW R422 Trench Rammer Petrol Engine

The R422 Rammer is ideally suited for the compaction of granular, mixed and cohesive soils in confined areas. Popular with both contractors and hire companies, the R422 offers a highly productive percussion rammer at 66KG (145 lbs). The contoured fuel tank provides the largest fuel capacity in its class and effectively baffles engine noise. Power is supplied by a Honda GX100 engine.

Features

– Elevated bellows placement for trench applications – Patented polyethylene slide bearings provide minimal internal wear – 11” ductile cast iron tamping shoe – 4” and 6” trench shoe options available – 5 YEAR WARRANTY ON BELLOWS AND PERCUSSION SYSTEM BEARINGS

THE SECRET TO OUR SUCCESS…

MBW achieves unmatched durability by using patented UHMW polyethylene slide bearings and spring separators on all rammers. These components last up to 6 times longer than their metal counterparts, create less friction and heat, preserve lubricant integrity, and produce less internal load for the engine to overcome. Compression springs made of stress relieved, chrome-silicon alloy steel and a percussion housing of lightweight, durable aluminum alloy provide the strength for all MBW rammers.

HAND/ARM VIBRATION

MBW is committed to reducing hand/arm vibration on its entire range of rammers. We have made significant progress without cutting back on rammer compaction performance. Hand/arm vibration levels have decreased between 25 & 60% across the range.

SMART RAMMER

The integral tachometer/hour meter ensures that the rammer is operating at maximum capacity. It also informs service personnel of proper maintenance intervals. Optional on the R422 and R442, standard on the R482.
