Abstract (en)
[origin: DE102005045681A1] The suction lifter, e.g. for large metal or glass sheets, has at least one sucker (4) with a switched underpressure and at least one motor lifting drive (2). A monitor (8) registers the weight of the load (3) being lifted by the lifting structure (5). If the monitor registers an excessive weight or that there is insufficient underpressure at the suckers a safety signal is generated which deactivates the lifting system and/or prevents any further lifting movement.
