ABSTRACT:
The apparatus is employed for transferring pipe to and from the floor of a drilling rig. It comprises a stationary trough located below the rig floor and a movable trough aligned with the stationary trough. The movable trough has a vertically movable rear end supported to be moved between lower and upper positions and an opposite front end slidably supported by structure at the rig floor. In the lower position the vertically movable front end of the movable trough is next to the stationary trough and in the upper position, it is above the stationary trough. The movable trough is employed for lifting and lowering pipe between the stationary trough and the rig floor. Clamps are employed for clamping the pipe to the movable trough when it is lifting or lowering pipe.
