Abstract: Apparatus for lifting an open top container, such as a drum, comprises a plurality of clamps each having shaped outer and inner jaws for frictionally gripping therebetween a corresponding sidewall portion of the container. A lifting mechanism closes the clamps and then lifts the container with the container suspended from the clamps. The apparatus is constructed so that the weight of the container increases the clamping pressure as the container is lifted. Other loads having an upright tubular sidewall can also be lifted. In one embodiment, the lifting mechanism employs wedges for closing the clamps, and in another embodiment the lifting mechanism employs linkages for closing the clamps.
