摘要

The vacuum suction unit (1), to lift and carry a cut stone block (2) and the like, has a base body (3) with a holder opening shaped to pass partially around the load, with a gas extraction opening (5). One wall (6) of the holder opening is pliable, to compensate for position and/or shape tolerances. The body incorporates a rubber elastic polymer, gel and/or liquid-filled cushions at least in zones.
