ABSTRACT:
Pipe-gripping heads are movable along a pipe-spanning frame to grip opposite ends of a pipe. The length of the pipe-spanning frame extends transversely of the length of a boom which is carried and movable elevationally by a lift truck. The pipe-spanning frame is carried by and can be moved longitudinally of the boom or swung about an upright axis relative to the boom or tilted by swiveling the boom. The boom can be shortened by swinging upward an outboard draw section.
