CABLE ANCHOR WITH ANTI-SPIN COUPLER

[0001] A grouted rock anchor assembly is provided by the invention which includes an elongate anchor which extends between a distal end and a proximal end and which comprises a flexible element and a rigid connector element which is engaged to one end of the cable element and which has a locking formation; a load bearing barrel which has a bore through which the connector element is received in engagement; a tensioning element engaged with the connector element between the proximal end and the barrel; a mechanical anchor engaged with the cable anchor towards the distal end; a faceplate on the body; and a locking tube which has a leading end and a trailing end and which encloses a length of the body, wherein the trailing end is adapted to pass between the barrel and the faceplate; and wherein the locking tube includes a locking element which is adapted to engage the locking formation to prevent the cable element from twisting when the mechanical anchor is engaged with a rock hole, in which the grouted rock anchor assembly is inserted, and when torque is applied to the tensioning element to force the faceplate against the rock face in load support and to clamp the trailing end between the barrel and the faceplate.
