ABSTRACT:
Pipe handling apparatus for picking up and laying down tubular goods used in land and offshore drilling operations. The apparatus includes a longitudinally extending main support frame; a longitudinally extending movable member including a trough for receiving and retaining therein tubular goods and having an end portion pivotally connected to the support frame; a lift mechanism for moving the movable member between a lowered, substantially horizontal, first position and an elevated, second position. The base member has a portion thereof defining a horizontal support surface extending parallel to and spaced from one or both sides of the movable member when the latter is in the first position; stack mechanism is provided for transferring tubular goods to and from the movable member when the movable member is in the first position. A dump mechanism is operatively associated with the movable member for transferring tubular goods from the movable member to the stack mechanism. A buggy or pusher is positioned in the trough to move tubular goods longitudinally along the trough. The invention also provides a brake for controlling movement of tubular goods from a derrick or other elevated surface to the movable member.
