ABSTRACT:
A container handling assembly for lifting one or two containers. The assembly comprises a first and second jaw captively connected for cooperative movement whereby the jaws close when a load is applied. If a single container is lifted on the first jaw, the second jaw pivots to clamp the container on the first jaw. If two containers are lifted the jaws close to safely clamp both containers. In the unloaded position the second jaw projects beyond the first jaw thereby facilitating insertion of the jaws into coupling pieces of containers to be lifted. A number of safety features are incorporated to prevent lifting unless the containers are correctly loaded and to prevent unloading unless a release is activated.
