ABSTRACT:
A spreader device for handling containers is provided with a substantially flat bottom surface in its non-operative condition. A swingable arm mechanism is provided at each end of the spreader, and when the spreader is properly located on top of a container the swingable arm mechanism is moved to extend twistlocks out from the interior of the spreader and insert said twistlocks into the top holes of the upper corner castings of the container. Power means are provided for the operation of the swingable arm and for turning the twistlocks into an inter-connecting position when located within the corner casting.
