Vacuum lifter The rolls are handled by means of a vacuum lifter that is suspended from ropes led off the hoist unit and stabilized in the highest lifting position by means of pins or frame below the crab frame. The vacuum lifting unit is fixed and guided free from vibrations in a mechanical arresting mechanism in the highest lifting position. This ensures that lowering can be started from a fixed position immediately after reaching the destination. This has a positive influence on the cycle times. The arresting mechanism consists of 4 mechanically operated guide arms. The vacuum lifting unit is equipped with the corresponding guide rails. 2.
