A drilling and bolting rig includes a carousel rotatable about a carousel axis and including a plurality of stations configured to support a plurality of consumables, one or more actuators, and a position sensor coupled to the carousel. The one or more actuators are configured to rotate the carousel about the carousel axis. The drilling and bolting rig further includes an electronic processor coupled to the one or more actuators and the position sensor. The electronic processor is configured to detect, using the position sensor, a rotational position of the carousel, and rotate, using the one or more actuators, the carousel based on the rotational position of the carousel.

Bolter

A drilling and bolting rig for performing drilling and bolting operations. The drilling and bolting rig includes a magazine for storing a consumable, a feed supporting a drill head for movement relative to a work surface, and a loader configured to retrieve the consumable from the magazine and load the consumable into the drill head. The loader includes an arm operable to engage the consumable. The arm is supported for both rotational and translational movement.

A cable feed tool includes a first support, a second support coupled to the first support, a first roller supported on the first support for rotation and configured to drive a cable, and a second roller supported on the second support for rotation and configured to drive the cable. The first roller is also supported for pivoting movement relative to the second support about a pivot axis. The second roller is also supported for translational movement relative to the first support.

Cable feeder and drill rig

A drilling rig includes a base and a rotation unit for drilling a hole in a mine surface. The rotation unit is moveably coupled to the base. The drilling rig further includes a cable feed device for feeding a cable bolt into the hole created by the rotation unit. The cable feed device is moveably coupled to the base and includes a pair of wheels and a transmission. The cable bolt is received between the pair of wheels. The transmission is coupled between the rotation unit and at least one of the wheels to transmit power from the rotation unit to at least one of the wheels.

Roof bolting cable bolt feeding device

A cable bolt lifting and feeding device that is a lightweight unit that mounts into a drill rig rotation unit. The device uses the mechanical power provided in the rotation unit to drive a set of wheels that engage with the cable bolt, causing the cable bolt to be pushed through the device and into a pre-drilled hole.
