ABSTRACT:
A workpiece handling assembly for gripping, manipulating and releasing a fixtured workpiece assembly for transport to and from and positioning in a workpiece welding station and the like by a hoist to minimize contamination of the welds comprising an inverted generally "U" shaped gripping and manipulating gripping device including a telescopically extensible horizontal crossbeam structure having depending support arms extending downwardly from opposite ends thereof. The lowermost ends of said arms have pivoted gripper jaw members journaled therein for rotary movement about a common horizontal axis, including foot formations shaped to interfit and grip convergent grip edges of triangular protrusions projecting from the workpiece. The gripper jaw members are movable to and from gripping relation with the triangular protrusions, and the gripper jaw members can be latched at diametrically opposite angular positions to support the workpiece in either of two relatively inverted positions. A mounting plate is provided for the workpiece having cantilevered and eccentrically mounted latching pins associated with locating pins to latch the workpiece on the mounting plate.
