The rock bolting drill rig can place bolts 5 to 8 feet long in spots with roof heights of 9 to 25 feet.

It features Atlas Copco’s Rig Control System (RCS), giving it precision and efficiency while drilling, bolting and positioning. Drillers have a choice of controlling operations using a COP 1132 or a COP 1435 hydraulic rock drill. The operating panel includes two multi-functional levers.

A new resin injection steering system, controlled from the operator panel, can load resin or cement grout cartridges into a pre-drilled hole without having to move the entire bolting unit.

Atlas Copco claims that, with a feed dead length of 3 feet 7 inches and a low cabin, the rock bolting drill has the best operating height in its class for restricted working areas in tunnels and mines.

Mounted on a four-wheel drive carrier, the Boltec S is powered by a 4-cylinder EPA Tier 3-approved diesel engine. It has single tripod suspension using the BUT 32 heavy-duty hydraulic boom and the rated capacity of its compressor at 5,400 rpm is 42 cfm at 101 psi.
