Russo Power Equipment carries the best selection of compactors and rammers to help reduce the size of waste material through compaction. Not sure which compactor best suits you? There are three main compactors in the construction industry: the plate, the road roller and the "jumping jack". Rollers are mainly used to compact crushed rock as a base layer under concrete or stone foundations. The plate compactor is used for creating a level grade by using a vibrating base plate. Lastly, the "jumping jack" compactor functions the same as the plate, only using a smaller foot which allows it to compact the backfill in narrow trenches.
