Abstract
An apparatus for installing cables or pipes in tunnels comprises a motorised vehicle. A cable/pipe positioning arm is at each end of the vehicle, which is controllable to move a cable/pipe from a temporary installation position to a final installation position. One or more cable/pipe sagging arms are spaced from the positioning arm at the other end of the vehicle which are controllable to apply a desired amount of sagging to a length of cable/pipe between adjacent final installation positions. The apparatus can be driven along the cable/pipe performing the positioning and sagging in a single sequence and in either direction.
