The scraper (box) is usually associated with the rapid, low-cost excavation of earth works or unconsolidated overburden, soils and sands and gravels. It comprises a box or bowl mounted on four wheels fitted with pneumatic fires which is either towed by a tractor or articulated and motorized. The front of the box is open and the leading edge is fitted with a blade which scrapes the surface of the mineral when the edge is lowered. To facilitate movement of material into the box (and reduce compaction of soils) the box may be equipped with a scraper elevator. It is not suitable for excavation of 'hard' rock, blasted rock or gravels containing boulders. The box is discharged by a ram acting upon a pusher plate.
