The present disclosure relates to an extendable apparatus, such as an extendable apparatus for a drill head, a drill head including an extendable apparatus, and a method of operating a drill head. The extendable apparatus includes a base section, a drive section, an extension section, and a functional section. The base section and the drive section are moveable with respect to the extension section and the functional section along a longitudinal axis. The drive section and the functional section are rotationally rigidly coupled to each other. The base section and the extension section are rotationally rigid coupled to each other, and the drive section and the functional section are rotationally moveably coupled to the extension section.

Extendable apparatus, drill head and method

A mesh handler for a mining machine includes a generally U-shaped frame arranged for receiving and positioning at least one mesh against a roof portion of an underground tunnel. The frame includes at least one generally U-shaped rail and a guide mechanism arranged for guiding the mesh along the rail in a direction substantially perpendicular to a longitudinal direction of the mining machine. Moreover, a mining machine including the mesh handler is provided.

Mesh handling device for mining or tunnelling equipment

A manipulator for providing drilling expendables to a drill head of an underground drill rig includes a gripper that is arranged to selectively grip and release the drilling expendables and to move the gripper between a first position facing a supply magazine and a second position facing the drill head. The manipulator is also arranged to automatically take and return expendables to and from the magazine and drill head. A supply device provides the expendables to a drill head of an underground drill rig having the supply magazine, and to an underground drill rig, as well as an underground mining vehicle.
