The wheels of each pair are resiliently biased into contact with the cable and at least one of each pair of wheels is driven by its own motor. A mechanical coupling is provided constraining one wheel of one pair to rotate conjointly with one wheel of another pair. In one embodiment the apparatus includes two pairs of traction wheels, each wheel being driven by a respective motor. The wheels on each side of the cable are mounted on a respective bogie. The bogies are carried on supports to move the wheels towards and away from the cable path and the wheels are resiliently biased into contact with the cable by an hydraulic jack connected from one support to the other.
