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.

Cable Bolt Feeder
The Joy cable bolt feeder top plate eliminates manual handling of large cable bolts, which can weigh in excess of 40kg, mechanizing the cable bolt feeding process. The Joy cable bolt feeder can reduce operator injuries commonly associated with continuous manual feeding. The easily serviceable, removable drive wheel segments and easy access single location lubrication points reduce downtime for scheduled maintenance. The cable feeder can be purchased individually and is retrofit-able underground to Joy HFX feed frames.
Performance and productivity
- Forward and reverse cable feed function.
- No Increase in top plate operational footprint to standard Joy top plate.
- Reduces the number of operators required to feed a cable bolt from two to one operator.
- Cable bolt feed time: ~8 seconds for an 8m cable bolt, significantly quicker than
manual feeding.
- Cable grip pressure control, providing enhanced compatibility for different cable bolt types.
Ease of maintenance
- Easily accessible lubrication points for pivot points on front of top plate.
- Replaceable drive wheel segments for ease of service on consumable components.
- No additional hoses inside top plate cable bolt feeder to maintain.
Safety
- No exposed pinch points and hazards clearly labeled.
- Counterbalance valves for pinch cylinder & feed motor integrated in top plate allows external hoses to be de-energized while not in use. This also provides cable bolt emergency support in event of power outage or hose failure.
- The Joy cable bolt feeder has been designed to MGD 35.1 and 41.
- Two hand control of cable feed function, with safety latch on cable grip function.
