Abstract
A support system is provided for a gear case of a rope shovel. The gear case supports a gear drive configured to drive rotation of a hoist drum, and the gear case includes a first end, a second end, and a longitudinal axis extending between the first end and the second end. The support system includes: a coupling for securing the gear case against translational movement relative to a rotating frame, the coupling oriented orthogonally to the longitudinal axis and configured to engage the rotating frame and a portion of the gear case; and a support member configured to be coupled to the rotating frame of the rope shovel and supporting the gear case, the support member permitting translational movement of the gear case relative to the rotating frame to accommodate flexing of the rotating frame.
