Abstract
A guide shoe for a mining machine includes a shoe body, a through hole, and a support. The shoe body is configured to engage a rack. The through hole extends between a first wall of the shoe body and a second wall of the shoe body, and the through hole extends along a central axis. The support is coupled to the first wall, and the support is configured to engage a shaft coupled to a drive sprocket engaging the rack. At least one of the shaft and the support is movable between a first configuration and a second configuration. The rotation axis is spaced apart from the rack by a first sprocket distance in the first configuration, and the rotation axis is spaced apart from the rack by a second sprocket distance in the second configuration.
