Onboard bolting products include roofbolters and rib-bolters. These machines use automation, advanced materials and a patented carrier system to increase speed, minimize wear and reduce maintenance costs. Joy’s design engineers continuously analyze and optimize space, performance, productivity, safety, ergonomics and maintainability. This ensures the extraction and roof support components complement each other to the maximum extent possible.
Onboard bolting products are designed to maximize the advance rate of continuous miners and roadheaders through faster bolting cycle times. The hydraulic roof and rib-bolters are compact modular designs and are made virtually wear resistant.
Joy’s onboard products outdate the “steel on steel”, “wear-out and replace” designs of the past. The patented carrier system eliminates the unnecessary maintenance and replacement of slides and bushings. Onboard bolting products use advanced materials, automation and patented designs to lower costs and improve bolting cycle times.
HFX and HMX Drill Units
The JOY HFX telescopic roofbolter is designed to be a key component in automated roofbolting systems. Mounted on continuous miners, roadheaders, or other mobile equipment, it provides fast reliable roofbolting. The highly reliable semi-automation system provides for either single lever auto-drilling or manual operation. The HFX is available seven different sizes with a choice of top plates.
The JOY HMX is a heavy duty, low maintenance drill feed for mast style roof bolting machines. It offers high value though reliability and durability. The patented HMX roofbolter features a set of hardened, corrosion resistant slide rods and sealed, automatically lubricated slide blocks which eliminates wear, reduces maintenance and increases productivity.
