Abstract

A cargo container handling implement, i.e., a grappler spreader, having the customary four grappling arms for the bottom lifting of piggy-back trailers and four latch units for interlocking with the top latch receptacles of cargo containers, and, in addition, a mechanism by which the latch units are adjustable with respect to the remainder of the grappler spreader in its lateral direction to enable the implement to support a container with the vertical plane of its outwardly offset side beyond the lateral extremities of the adjacent pair of upwardly stored grappling arms.
