Cable bolting rigs

Cable bolting rigs are specialized machines designed to drill deep clean holes and install long, flexible cable bolts to reinforce and stabilize large rock masses in underground mining and civil tunneling projects.

Quality controlled cable bolting with high productivity

The unique two-boom concept of Epiroc's cable bolting rigs makes it possible for a single operator to drill and install cable simultaneously. The rig is capable of installing cable bolts with lengths up to 25 meters. Its computerized Rig Control System, RCS, includes functions such as one-hole automatics for high productivity and fully adjustable drill parameters for optimal drill quality and drill steel economy.

Safety

The cable bolting rigs from Epiroc offers excellent operator safety and ergonomics thanks to the FOPS certified protection roof or optional cabin, with full mechanization of the drilling, grouting and cable pushing processes. All operations are performed from within the operator station. Therefore, exposure of the operator to heavy lifting, unsafe ground, and other hazards are significantly reduced.

Quality

With cable bolting rigs from Epiroc, both drilling and grout mixing quality are assured. Single hole automatic drilling with precise positioning sensors will ensure that the hole is drilled where it was planned and to the depth required. Load cells and programmable mixing ratios will guarantee the correct grout consistency that is required to achieve the necessary load transfer from the rock mass to the bolting cable.
