Mobile bolting products are designed to increase the safety and efficiency of place change mining methods. These products range from compact pneumatic cable bolters to electro-hydraulic dual and multi-head bolters.
Mobile bolting products range from pneumatic, single head cable bolters to automated, multi-head roof and rib-bolters. Joy offers a wide variety of mobile products available with either percussive or rotary drilling units.
The multi-head bolters are known for their speed and reliability as well as their durability. The smaller bolters are known for their use of advanced materials, compact design and their cost-effective solutions to roof and rib-bolting.
JOY Cablebolters are available in various configurations. The compact designs allow quick and efficient bolting in numerous applications. The electro-hydraulic cablebolters have the ability to install bolts up to 49 feet (15 m) long.
In addition to bolters, Joy offers a broad range of gas drainage equipment. This includes machines for gas drainage (in-seam and cross measure), exploration, instrumentation, face proving, resin injection, core drilling and water infusion.
The JOY quadbolter is a high capacity “place change” roofbolter. It features four HFX bolting units. The HFX is a patented, semi-automatic, wear resistant bolter that minimizes maintenance and downtime. The quadbolter is available in either wet or drydrill models and capable of operating in heights from 7.5 to 14.7 feet (2.3 to 4.5 metres).
The quadbolter features a proven track system similar to the systems used by JOY continuous miners. This provides excellent tractive effort, low ground pressure and a robust base even in difficult floor conditions. To improve safety, the quadbolter is equipped with a temporary roof support system and a protective canopy for its operators.
