At least one attachment point is proximal one end of the top wall, and at least one attachment point is proximal an opposing end of the top wall, wherein the girder is fixable to a mining shovel frame at each of the attachment points. Preferably, each attachment point is fixed to the mining shovel frame with at least one bolt. Most preferably, the swing girder is mounted to the frame, and hangs below the frame to engage the ring gear.
