Suction lifting apparatus for use with horizontally disposed paper rolls has a frame (18) from which depend suspension members (19) supporting suction grippers (7), the suspension members being supported by carriages (3, 4) which are movable along the frame to vary the distance therebetween by power cylinders (10, 12, 13). The cylinders may be movable individually or together and the apparatus can be retained in equilibrium by movement of a suspension carriage (1) along a surface (20) by a cylinder (11). The grippers are both curved and pivotally mounted to enable them to intimately contact the surfaces of the rolls. <IMAGE> |
