TENSIONING DEVICE

摘要

A tensioning assembly for a cable bolt having a shaft, the tensioning assembly comprising: a base member securable to the shaft so as to be fixed with respect to the shaft; a bearer member moveable with respect to the base member in the direction of a longitudinal axis of the shaft but inhibited from rotating relative to the shaft about that axis; and an actuator engageable with the bearer member and the base member so that a predetermined movement of the actuator effects longitudinal movement of the bearer member with respect to the base member which in use allows for tensioning of the cable bolt.
