  • Patent number: 8308210
    Abstract: A lifting grab for grabbing and lifting drums and/or other objects includes: a lifting point having two or more lifting arms radiating therefrom, the arms each having rim engaging elements, at least one arm is an articulated arm movable between engaging and non-engaging positions. A drum can be grabbed by initially attaching the engaging elements of the non-articulated arms to the rim, the at least one articulated arm then brought into the rim engaging position for attachment to the object or rim. Applying an upward or lifting force to the lifting point causes the rim engaging elements of all lifting arms to forcibly grab the object or rim of the drum, and whereby on releasing the lifting force, the at least one articulated arm is first disengaged from the rim thereby also relaxing the grip of the non-articulated arms wherein the drum or object can be released from the grab.
