An industrial machine includes a frame having a base and a boom, an arm movably coupled to the boom, an attachment, a conduit, a first member, and a second member. The boom has a first end coupled to the base and a second end opposite the first end. The arm includes a first end and a second end. The attachment is coupled to the first end of the arm. The conduit extends from the frame to the arm. The first member is pivotably coupled to the frame and supports a first portion of the conduit as the arm moves relative to the boom. The second member is pivotably coupled between the first member and the arm, and supports a second portion of the conduit as the arm moves relative to the boom.

A rope shovel has a boom and a hoist rope. The boom has a first end and a second end. The hoist rope extends over the second end of the boom. A digging assembly for the rope shovel includes a shaft, an elongated member supported for movement relative to the boom, an attachment, and a drive link. The shaft is positioned between the first end and the second end of the boom and transverse to the boom, and the shaft includes at least one pinion gear. The elongated member includes a first end and a second end. The attachment is coupled to the first end of the elongated member and is configured to be coupled to the hoist rope. The drive link includes a rack engaging the pinion gear of the transverse shaft such that rotation of the pinion gear moves the drive link and actuates the attachment.
