Abstract
Abstract A self aligning latching mechanism on a cargo container spreader, the mechanism mounted so as to surround a post of the spreader and including biasing means to normally keep the post substantially vertical whilst allowing the post limited movement upwardly against the action of the biasing means to a position where its longitudinal axis can be displaced to a slight angle to the vertical. The mechanism serves to allow the spreader to be connected to a container which has one or more of its recesses out of alignment.
