ABSTRACT:
A device for attaching a lifting mechanism to a container provided with an aperture through its end wall comprises a probe member secured to the lifting mechanism and including a head portion for location through the aperture in the end wall of the container, and having a surface for abutting a region of the inner face of the end wall bounding the aperture. The probe member further includes a body portion projecting from the container and provided with a surface which abuts a substantially diametrically opposed region of the outer face of the end wall bounding the aperture. On raising the lifting mechanism, the probe member engages the underside of the upper bounding wall of the aperture and is retained in this operative position by co-operation between the surfaces on the head and body portions with the surfaces on the inner and outer faces of the end wall of the container respectively.
