A method for controlling of a vacuum - hoists and load-securing device for the partial vacuum - hoisting equipment as well as their use

摘要

Method for the operation of a vacuum - lifting gear (1) having at least one elastic, for generating a displacement under pressure resistant under pressure during the lifting jacks (4) and with switchable negative pressure, as well as with at least a motorized lifting unit (2), with the use of a load detection means (8) for detecting the weight of a of the hoisting machine (1) load taken up (3), characterized in that the load detecting means (8) according to the detection of a a predetermined tare weight (t) of the hoisting device (1) in the case of not the negative pressure or an inadequate vacuum (v) exceeding a load (3) a security signal is generated, which the lifting unit (2) by means of a system (2s) directly or indirectly deactivated and / or a further lifting of the load is prevented if, in the case of a detected load and of the resulting stroke, no or no sufficient pressure difference is applied.
