Abstract

Abstract The disclosed machines and method are utilized to expeditiously remove the engines, and the transmissions connected thereto, from junked vehicles, such as automobiles, trucks, and the like and are particularly adapted to remove engines-transmissions that are mounted in engine compartments, in which one end of the enginestransmissions extends beyond one end of the engine compartments. The machines include a pair of hydraulically actuated tongs which are adapted to grip the sides of the engine to be removed while the engine is mounted in the engine compartment of the vehicle. The tongs are constructed so as to permit limited, relative pivotal movement between the engine and tongs. The tongs are pivotally mounted on one end of a vertically movable boom structure which, in turn, is mounted on a portable frame adapted to be positioned adjacent to the engine compartment of the vehicle while the engine is being pulled from the engine compartment. The machines also include hold-down members which are used to restrain vertical movement of the vehicle while the engine is being removed and control means for permitting one person to control the entire operation of the machines. During the operation of the improved machines in accordance with the improved method, the engine to be removed is gripped by the tongs and is moved vertically so that the other end of the engine is pulled from its engine mounts. The engine is then pulled, at an angle with respect to the vertical, so that the one end of the engine, and the transmission, are removed from the engine compartment along a substantially straight path. In one of the disclosed machines, the one end of the boom structure is extendable, with respect to the rest of the boom structure, and a pair of forks are mounted on the extendible end of the boom structure adjacent to the tongs so that the machine may also be utilized as a fork lift. In this machine, the tongs and hold-down members are both movable to positions where they do not interfere with the operation of the machine as a fork lift. In the other disclosed machine, the frame may be permanently mounted on a chassis or may be selectively carried by a fork lift truck or the like.
