Abstract
Disclosed is a rock bolt installation tool for installation of a rock bolt assembly into a predrilled rock hole. The tool includes a drive shaft having a proximal end, which is adapted to engage with a drill rig, and a distal end. A socket in the distal end includes a first containment portion, of a first diameter, which has a base and a second containment portion, of a second diameter, between the first containment portion and the second end. The first containment portion is adapted to receive a nut of the rock bolt assembly. The second containment portion is adapted to receive a load-indicator of the rock bolt assembly. The base and the second end are adapted to provide surfaces against which the nut and a spherical seat of the rock bolt assembly respectively engage to be driven into the rock hole.
