Abstract: A material press includes a base portion defining a generally horizontal bed upon which a vehicle (or other material) to be crushed may be placed. Material placed on the bed is crushed by a lid portion which is slidably movable relative to the base along a pair of vertical guide mechanisms by a pair of hydraulic cylinders. Each vertical guide mechanism includes two guide posts. Guide sleeves which slide along the posts are pivotally connected to the four corners of the lid by pivot linkages. The casings of the hydraulic cylinders are movable between a raised position for performing crushing operations and a lowered position to reduce the overall height of the crusher during transportation between job sites. A locking mechanism is provided for quickly locking and unlocking the cylinder casings in their raised position. The base of the material press may be form of a semi-trailer to permit the press to readily be moved between job sites.

Abstract: A shear baler is disclosed which is designed to efficiently process large volumes of desparate scrap metals into discrete, high intensity, compact bundles and includes novel structure for the facile mounting of shear blades in the movable shear ram and for preventing damage to the side mount ram due to scrap metal working around the ram head.
