A drill rod handler provides rods to be used to form a drill string in on-shore drilling operations. The drill rod handler includes side arms which are moveable to encourage drill rods to roll towards or away from a centre line of the drill rod handler. A working arm is arranged to grasp a centrally located drill rod, and to raise it from a horizontal to a vertical configuration. The working arm may then slew to correctly position the drill rod at the correct location for use. |
