ABSTRACT:
Disclosed herein is a cargo container spreader arranged as an articulated assembly of which a main frame or spreader portions supporting a cargo container may be shifted in substantially universal angular movements relative to a spreader supporting facility, such as a crane, through suspension of the main frame on a pair of spaced upright subframes with respect to which the main frame is horizontally movable in its transverse direction. Skewing of the main frame occurs when it is shifted relative to the subframes in opposite transverse directions.
