Abstract: A bit changer assembly includes a bit basket actuator assembly configured to be coupled to a drill rig. The bit basket actuator assembly includes an actuator, a guiderail, and a bit basket that is movably coupled to the guiderail via actuation of the actuator. The bit changer assembly also includes a bit carousel configured to be coupled to the drill rig, such that the bit carousel is rotatably and vertically moveable relative to the drill rig.

Abstract: A breakout wrench assembly for a drill rig includes two support shafts. Each of the two support shafts is configured to extend in a direction relative to a drill pipe on a drill rig. The breakout wrench assembly also includes a carrier coupled to the two support shafts. The carrier is movable linearly along the two support shafts. The breakout wrench assembly also includes a breakout wrench pivotally coupled to the carrier or to one of the two support shafts. The breakout wrench includes a first end coupled to the carrier or to one of the two support shafts, and a second, opposite end configured to engage the drill pipe.

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.
