  • Seven models available, with single-pass roof bolt lengths ranging from 1.8 to 3.5 meters
  • Auto drilling or manual operations
  • Available in a rib bolter version
  • Chrome cylinder feed mechanism eliminates wear

The HFX roofbolter can be mounted on continuous miners, roadheaders, entry drivers, miner bolters, or other mobile equipment. Seven models are available with a full range of retracted and extended lengths, and a choice of top plates and rotation units, to meet virtually all roofbolting needs.

Designed for speed, safety, and reliability

The semi-automatic HFX can run in either auto-drill or manual modes. The mast-mounted integrated control module (ICM2 or ICM 3) handles the auto-drill and return cycles. In addition, the HFX features auto water on/off and mast extend/retract functionality during the drilling cycle.

A critical safety feature is the ability to disable the auto-drill function by simply pressing a single button.

The completely sealed carrier unit eliminates wear to the hardened chrome slide bars. In addition, the carrier/slide bar integration provides outstanding structural stiffness.
