Abstract: A mining shovel includes a base for supporting the shovel on a support surface, a boom, an elongated member movably coupled to the boom, and a support member. The boom includes a first end pivotably coupled to the base and a second end positioned away from the base, the boom being pivotable about a boom pivot axis extending transversely to the boom proximate the first end. The elongated member is pivotable about a shaft positioned between the first end and the second end of the boom. The support member biases the boom against pivoting movement about the boom pivot axis, and the support member extends between the base and the boom.

Abstract: A mining shovel includes a digging assembly having a generally V-shaped boom including a lower connection point for attachment to the mining shovel. A first portion of the boom extends generally upwardly from the lower connection point, and a second portion of the boom is angled with respect to and extends upwardly and forwardly from the first portion. The second portion includes a distal end defining a sheave support, and a pivot element is positioned generally at a connection area between the first portion and the second portion. The digging assembly also includes a boom attachment having a first end that is pivotally supported by the pivot element and a second end that is supported by the sheave support.
