ABSTRACT:
A drum clamping unit for plastics material drums with peripheral "L'8 chime rings below the drum head is adapted to be mounted on suitable lifting and transporting devices such as lift trucks, overhead cranes, and the like to automatically engage, latch onto, and discharge one or more of the molded plastics material drums without damaging the drums. The unit has a plurality of clamping jaws automatically triggered to clamping positions by the drum heads as the unit is lowered alongside the drums. These clamping jaws are positioned to engage only with the bottom and inner face of the "L" chime ring of each drum and remain clear of the drum head and drum periphery thereby avoiding any damage to the drums especially as they are raised to clamp onto the "L" rings. Then, when the raised clamped drums are conveyed to and lowered on a desired location, the jaws are released, retracted automatically and held in a retracted position until the unit is again lowered to engage a drum head in a subsequent operation. A preferred unit handles up to four upright drums positioned in a ring cluster or nest.
