Abstract
A method and apparatus for removing a closure from a center-fill drum opening. The apparatus includes a clamping mechanism and a load transfer assembly coupled to the clamping mechanism and including a drive element engageable with the closure and movable relative to the clamping mechanism to force the closure inwardly of the drum. The assembly is arranged so that the element is eccentric with respect to the opening.
Claims8
An apparatus for removing a closure from an opening in a drum, comprising:
- a clamping mechanism for securing the apparatus to the drum;
- and
- a load transfer assembly coupled to the clamping mechanism and including a drive element engagable with the closure and movable relative to the clamping mechanism to force the closure inwardly of the drum, wherein the clamping mechanism is adapted to fit about the periphery of the opening, and the assembly is arranged so that the drive element is eccentric with respect to the opening.
A method for removing a closure from an opening in a drum, comprising the steps of;
- fitting a clamping mechanism to the drum;
- exerting a compressive force between the mechanism and the closure, eccentrically of the opening, so as to deform the closure inwardly of the drum;
- and
- lifting the closure clear of the opening thereby removing the closure from the opening in the drum.
