ABSTRACT OF THE DISCLOSURE An apparatus for transferring tubulars between pipe racks and a drilling rig floor including a stationary trough located below and extending towards the drilling rig and a movable trough aligned with the stationary trough having one end supported on the drilling rig floor and the other end powered to move between a lower position for transferring pipe to and from the stationary trough and on upper position for transferring pipe to and from the drilling rig floor. A carriage driven by an endless chain pushes and guides the pipe along the stationary trough. Two pair of legs extending between pipe racks and the stationary trough are provided. A portion of the stationary trough in the loading location is caused to tilt between a tilted position for accepting pipe from the loading legs and a level position flush with the rest of the stationary trough whereby pipe may easily slide to and from the movable trough. The lower end of the movable trough is lifted and lowered by a drive system associated with a pair of masts connected to the stationary trough.
