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.

A flexible conduit dispenser case is disclosed. An outer body defines an inner chamber where flexible conduit can be coiled. The flexible conduit is coiled around a rotating hub, which makes the flexible conduit easier to dispense. The flexible conduit dispenser case can be locked to help to retain the flexible conduit. The flexible conduit emerges from an exit port on the handle of the flexible conduit dispenser case for ease of access and control. Also disclosed is a planar base which holds the flexible conduit dispenser case in position for increased ease of dispensing the flexible conduit and engagement members on the rotating hub increase the retention of the flexible conduit.

Techniques for implementing and/or operating a pipe deployment system that includes pipe deployment equipment, in which a pipe drum having spooled thereon a pipe segment is to be loaded on the pipe deployment equipment, and a pulling device to be secured to an unspooled section of the pipe segment. The pulling device includes a device body having a first body arm and a second body arm, in which the device body is to be disposed around the unspooled section of the pipe segment, the first body arm is to be secured to a first cable branch, and the second body arm is to be secured to a second cable branch. The pulling device includes a first pipe grabber secured to the first body arm and a second pipe grabber secured to the second body arm such that the second pipe grabber and the first pipe grabber open towards one another.

A device for imparting a torsional force onto a wire has a base and a support mounted so as to be rotatable with respect to the base around an axis of rotation. The axis of rotation coincides with a wire path extending through the base and the support. Further, a wire clutching device is mounted on the support and adapted to engage at a wire guided along the wire path, and a rotation mechanism is provided which is adapted for rotating the support with respect to the base.

The present disclosure relates to a device for unstowing an electrical supply cable from a storage chamber disposed within an underground service pit. The cable is configured to electrically connect to an electrical power supply at a first end and to connect to an external power socket of an aircraft at a second end for supplying electrical power to the aircraft. The device includes a cable guiding wheel that is disposed at ground level above the underground service pit and configured to receive the cable. The device also includes a motor coupled to the cable guiding wheel that is configured to drive the cable guiding wheel. Upon activation, the motor rotates the cable guiding wheel to generate a pulling force on the cable to at least partially lift the cable out of the storage chamber.
