ABSTRACT:
Method and apparatus for transporting pipe between spaced locations comprising a cable disposed in proximity of the two locations which supports a pipe receiving trough so that the trough can be moved by the cable to enable a pipe supported therein to be transported between the two locations. The tension in the cable is adjusted to enable the trough to be moved in a vertical plane. In one of the embodiments, the trough is directly attached to and moved with the cable. Longitudinal motion imparted into the cable causes the trough to move from one location to the other carrying the pipe therewith. The cable is slackened to vertically move the trough so as to enable the pipe to be placed within or removed from the trough. In another of the embodiments, the trough is attached to spaced carriages which are slidably supported from the cable. A pilot cable attached to the trough enables the trough to be moved longitudinally of the cable to enable transportation of the pipe between the spaced locations.
