Abstract
A mining shovel including a base, a boom, a first member moveably coupled to the boom, a bucket, and a pivot actuator. The base includes a hoist drum for paying out and reeling in a hoist rope. The boom includes a first end coupled to the base and a second end opposite the first end. The hoist rope extends over the second end of the boom. The first member includes a first end and a second end. The bucket is pivotably coupled to the second end of the first member. The pivot actuator moves the bucket relative to the second end of the first member, and the pivot actuator includes a first end coupled to the first member.

A digging assembly for a rope shovel, the rope shovel including a boom having an end, the rope shovel further including a hoist rope extending along the boom and passing over the end of the boom, the digging assembly comprising:
- a handle including a first end and a second end, the handle configured to be supported for rotational movement and translational movement relative to the boom;
- at least one actuator including a first end and a second end, the first end coupled to the handle;
- a bucket including a wall and a body, the wall having a first side and a second side, the first side pivotably coupled to the second end of the handle at a wrist joint and coupled to the second end of the actuator, the body including a material receiving opening, a material discharging opening, and a digging edge extending along at least a portion of the material receiving opening, the body pivotable relative to the second side of the wall to selectively close the material discharging opening, the wall configured to be supported by the hoist rope at a bail joint, the bail joint positioned proximate the second side of the wall and offset from the second side.
A digging attachment for a rope shovel, the rope shovel including a boom, a hoist rope, and a handle, the boom having an end, the hoist rope passing over the end of the boom, the handle supported for movement relative to the boom, the digging attachment comprising:
- a wall defining a first side and a second side opposite the first side, the first side including a wrist joint configured to be pivotably coupled to an end of the handle;
- a body pivotably coupled to the wall, the body including a material receiving opening, a material discharging opening, and a digging edge extending along at least a portion of the material receiving opening;
- and
- a bail pivotably coupled to the wall at a bail joint, the bail configured to be secured to the hoist rope, the bail joint positioned proximate the second side of the wall and offset from the second side of the wall.
