A hoist rope connector for a rope shovel includes a link extending between a first end and a second end. A rope attachment member is positioned adjacent the first end and configured to engage a hoist rope. A spherical coupling is positioned adjacent the second end and configured to be coupled to a dipper. The spherical coupling permits rotational movement between the second end and the dipper in multiple directions.

Digging attachment support for shovel

A rope guide that includes an arm, a rope-contacting element, and a spring damper. The rope guide is pivotably coupled to the boom of a mining shovel. The combination of the arm, spring damper, and rope-contacting element maintains a nominal tension in the rope, thereby reducing the likelihood of wear and fatigue on the rope.
