Abstract
A surface mining shovel having a frame, a boom extending upward from and pivotally mounted on the frame, a handle pivotally mounted on the boom, and a dipper mounted on the handle at a position enabling engagement of the dipper with earth material as the handle pivots. A
hoist is connected to the handle for pivoting it to engage the dipper with the earth material and lift the dipper. A crowd mechanism is connected between the frame and the boom for pivoting the boom and moving the dipper on the handle into the earth material whereby the earth material enters the dipper and can be lifted with the dipper as the handle is pivoted by the hoist. The crowd mechanism is positioned between the frame and the boom such jacking movement of the boom is prevented during crowd operation. The crowd mechanism is preferably of a hydraulic type having a cylinder and a piston which is hydraulically extended from and retracted into the cylinder. The frame may include a gantry support extending upward and the crowd mechanism, in such case, is connected to the gantry support. The hoist means may be connected to the handle at a location generally above the boom and preferably comprises a wire rope hoist for pivoting the handle on the boom. The handle may include an upper section normally extending a distance above the boom and the hoist is connected at or adjacent to the outward end of the upper section of the handle.
