Abstract
A pipe handling device for transporting pipe, drill collars, or like tubular members between the elevated drilling floor of a well derrick and a lower storage area has a pair of support cables extending between the rig floor and the storage area. A pipe trolley means rides the support cables and is movable along the support cables by a third cable to transport pipe from the storage area to the rig or to lay pipe down from the rig to storage. A cable draw works, typically in the vicinity of the storage area, anchors one end of the support cables and is provided with a take-up mechanism for the support cables to enable them to be slackened to enable a pipe to be loaded into or unloaded from the pipe trolley means in the storage area and thence tensioned to facilitate the travel of the trolley to the elevated rig floor.
