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.
