Abstract

Abstract A device and system for picking up pipe, which is arranged horizontally on a rack, putting the pipe in position to be run into the bore hole of a well, removing the pipe from the bore hole of the well and conveying it to a position to be returned to a horizontally racked position. The device utilizes a hydraulic elevating mechanism to move the pipe into position, to be moved by a cable supported and cable actuated power conveyor, to be picked up while horizontally arranged on a rack, and conveyed semi-automatically to a position adjacent the drilling rig to enable pipe elevators to be attached to the pipe for suspending the pipe in a derrick to be attached to the length of the pipe therebelow to be run into the bore hole of the well, and to be removed from the bore hole of the well, whereupon the pipe is directed onto a trolley for movement down a cable supported and cable actuated power conveyor, to be discharged horizontally from the conveyor onto a pipe rack. A modified form of the invention, for use with a wheeled carrier on a track, enables the pipe to be moved the length of the supporting trackway.
