Abstract
The invention comprises an accessory for use with a driver for forceably inserting friction rock stabilizers into bores formed in earth structures (such as mine roofs). In the depicted embodiments, the Accessory comprises an elongate body having a driver element with a pin or boss at one, lower, 'driven' end of the body for engaging and supporting an end of a stabilizer, and a second driver element with a socket, at the opposite, upper, 'driving' end of the body for receiving an insertion tool. The latter driver element can be pivotably offset, to accommodate an angled, unobstructed address of the insertion tool to the upper end of the body, and to enable a linear insertion of a stabilizer, supported on the lower end of the body, into a bore. In accommodating a driver at the upper end of the body, to forceably insert a stabilizer which has its termination supported on the lower end of the body (the insertion force, therefore, being applied through the body), the Accessory facilitates bore insertion of lengthy stabilizers, by means of conventional tools, in low headroom, subterranean openings.
