<p>The present invention relates broadly to a tensioning device through which a strata support cable 12 or tendon passes. The cable 12 is installed into an elongate cavity drilled into a geological strata (not shown). The tensioning device 10 includes a tensioning member 14 which has a central elongate bore 16. The elongate bore 16 is adapted to receive the strata support cable 12. The tensioning member 14 has a threaded portion 18 for threaded engagement with an actuator member or relatively large nut 20. The tensioning member 14 also includes a wedge assembly 22 for securing the table 12 or tendon to the tensioning member 14 to prevent the cable 12 or tendon pulling through the elongate bore 16.</p> |
