A tensionable cable bolt assembly

摘要

A TENSIONABLE CABLE BOLT ASSEMBLY A tensionable cable bolt assembly (100) has a cable (110) longitudinally extending between a cable leading end (111) and a cable trailing end (112). A tensioning member (120) is mounted on the cable (110) toward the cable trailing end (112). The tensioning member (120) comprises an externally threaded, leading tubular element (121) and a trailing drive head (122) fixed in relation to the tubular element (121). The tensioning member (120) has a cable aperture (123) extending through the tubular element (121) and the drive head (122). The cable (110) extends through the cable aperture (123). An external member (130) is mounted on the tubular element (121). The external member (130) has an external member trailing face (132) and an external member leading face (131) adapted to engage a rim of a mine plate through which the cable (110) extends in use. The external member (130) has an internally threaded external member aperture (133) threadingly engaging the tubular element (121). A barrel and wedge assembly (150) is mounted on the cable (110) between the drive head (122) and the cable trailing end (112). The cable (110) is freely rotatable relative to the external member (130) and freely rotatable relative to the tensioning member (120), at least upon application of a predetermined torque.
