A compactor is a machine or mechanism used to reduce the size of waste material or soil through compaction.
Normally powered by hydraulics, compactors take many shapes and sizes. In landfill sites for example, a large bulldozer with spiked wheels is used to drive over waste deposited by waste collection vehicles (WCVs).
Different compactors are used in scrap metal processing, the most familiar being the car crusher. Such devices can either be of the "pancake" type, where a scrap automobile is flattened by a huge descending hydraulically-powered plate. The other type is the baling press, where the automobile is compressed from several directions until it resembles a large cube.
These compactors are almost exclusively of welded steel construction for two reasons: durability under pressure and exposure to the elements, as compactors are installed either completely outdoors or sometimes under a covered loading dock.
