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 dry drill models and capable of operating in heights from 7.5 to 14.7 feet (2.3 to 4.5 meters).

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.
