A lifting attachment comprises a columnar body (10) having anchorage means (12) at its top to be connected to a lifting apparatus. First and second mounting means (14, 16) are provided on the body (10) in vertical spaced relation. One of said mounting means (14 or 16) is adapted to be moved towards and away from the other of said mounting means (16 or 14) which is stationary. A series of gripping mechanisms each includes a radiating arm (18) pivotally attached at its inner end to a respective mounting on one of said mounting means (14 or 16). The arms (18) are similarly shaped at their outer ends each as a gripping finger (22). Each arm (18) is in a pivotal relationship with a corresponding mounting on the other of said mounting means (16 or 14). Movement of one of said mounting means relative to the other of said mounting means causes the arms (18) to splay apart from the body (10) into a gripping position. Means is provided to move one of the mounting means. An assembly is provided to support a plurality of lifting attachments. |
