Vertical Rammer

MBW Rammer

Our Vertical Rammers are made by MBW. The R-422 vertical rammer compactor features an 11" by 13" shoe and puts out 3,400 lbs of compaction force at up to 720 blows per minute. It is powered by a 4 cycle Honda engine so you do not need any mixed fuel with two stroke engine oil. The rammer features an excellent weight balance to minimize operator fatigue. It is capable at traveling up to 55 feet per minute, dependant upon soil conditions. These units are great for compacting cohesive soil like clay or for compacting larger lifts than possible with a vibratory plate compactor. Vibratory plate compactors are great for flat work with lifts up to 4" but our vertical rammer can be used on lifts up to 18". Actual compaction depth will vary as to soil condition and they tend to bury themselves in deep loose soil to the point where it gets much harder to maneuver. It's "foot stomping" compaction action will leave a rough finish when you are done. If you will be laying concrete flatwork over the top we recommend finishing up with a vibratory plate compactor. The vertical rammer will excel in trench work or deeper work holes. For more info on the vibratory plate compactors please Click Here to access that page.

The vertical rammers are reasonably heavy so it will take 2 men to lift them. They fit well in the back of vans, pickup trucks, SUVs, or small trailers but do not go into car trunks.
