Abstract
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.
