Abstract
A device for lifting and handling open end drums, especially fiber, or other non-metallic drums includes a support, an inner member and toggle clamps mounted on the support. The toggle clamps cooperate with the inner member to engage the open top of the drum. The drum can then be lifted by engaging and lifting the support.

A device for engaging a drum having a cylindrical rim defined by a drum inner surface and a drum outer surface, said drum surfaces extending in parallel, said device comprising:
- a support;
- an attachment mounted on said support for attachment to a lifting device;
- a ring attached to said support, said ring having a ring outer surface conforming in size and shape to said drum inner surface wherein said ring outer surface is disposed adjacent to said drum inner surface when said support is positioned on said rim;
- and
- a plurality of clamps mounted on said support and disposed peripherally about said ring, each clamp having a clamping surface pivotable between a first and second position, said clamping surface in said second position contacting said drum outer surface and cooperating with said ring outer surface to engage said rim therebetween, each of said clamps further comprising independent locking means for locking said clamping surface in said second position independently of the other clamps.
