Abstract: A throat formed between jaws of a rigid bifurcate gripper can be moved horizontally to receive an edge portion of sheet structure. The gripper is freely tiltable so that application of a lifting force to it will effect tilting of the gripper relative to the sheet structure to bind such structure between the jaws. Normally the gripper is positioned by a counterweight with its elongated throat horizontal. The lower jaw is of reflex angle shape and is positioned relative to the upper jaw so that downward tilting of the jaws will cause them to bind the sheet structure in the gripper throat.

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.
