Abstract: A pipe, beam or other work piece is detachably secured to a handling device affixed to the extremity of a conventional telescoping crane boom, the handling device including a main frame, a sub-frame, and a work piece support frame. Respective hydraulic actuators selectively position the sub-frame relative to the main frame and the support frame relative to the sub-frame. One actuator rotates the sub-frame about a transverse axis and the other actuator rotates the support frame about a longitudinal axis. The work piece supporting frame includes means for detachably holding a work piece during handling periods, permitting the work piece to be positioned at any desired attitude, orientation and elevation by appropriate actuation of the hydraulic system.
