A plate compactor is a very basic machine in construction machinery. It is used to compact soil, granite, and other materials, especially in roadway building, foundation establishing and other construction projects. It is a machine or mechanism used to reduce the size of material such as waste material or biomass through compaction. The plate compactor (vibratory rammer) has a large vibrating base plate and is suited for creating a level grade. It is working in such way that the machine transmission power from the engine to the base plate via a continuously vibrating hammer, a stress forced into the soil and extrude inside air and waste materials to compact soil.
