Abstract
A wedge device is movable to alternatively engage and disengage the upper portion of the bowl liner of a crusher. The wedge device comprises a wedge having a forward portion and a cavity configured to receive a cylinder. At the rearward portion of the wedge device is a bolt. A threaded end of the bolt is configured to mate with a like-threaded nut. The wedge device is positioned such that the head of the bolt contacts an outer surface of the crusher. A cylinder is placed within the cavity. When the cylinder is pressurized, the wedge nose engages the bowl liner. The nut is then easily rotated and moved into a “holding” position behind the rearward portion of the wedge. The cylinder can then be removed from the wedge cavity and moved for use with another wedge device. A lock plate can be used to prevent rotation of the nut.
