PIPE HANDLING APPARATUS WITH CLAMPING MEANS FOR TROUGH OF PIPE HANDLING APPARATUS Abstract of the Disclosure 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 provided for clamping a length of pipe to the trough of a pipe handling apparatus. The clamps comprise two arms pivotally coupled to the trough on opposite sides thereof. The arms are movable to open and closed positions by two piston rods pivotally coupled to the arms and which are actuated by two cylinders pivotally coupled to the trough on opposite sides.
