METHOD FOR RAISING AND/OR LOWERING A LOAD-HANDLING ELEMENT OF A LIFTING DEVICE, IN PARTICULAR OF A CRANE, AND LIFTING DEVICE THEREFOR

The invention relates to a method for raising and/or lowering a load-handling element (9) of a lifting device (6), in particular of a crane (1), wherein the lifting device (6) can be operated at leastwith a first velocity (v1) or with a second velocity (v2) by means of a control unit (15, 15a) in or...

Zusammenfassung:The invention relates to a method for raising and/or lowering a load-handling element (9) of a lifting device (6), in particular of a crane (1), wherein the lifting device (6) can be operated at leastwith a first velocity (v1) or with a second velocity (v2) by means of a control unit (15, 15a) in order to raise and/or lower the load-handling element (9), the first velocity (v1) being less than the second velocity (v2). In order to achieve a reduction in impulses during the raising of the load-handling element (9) and in particular an extended service life of the supporting means (8) in a corresponding method, it is proposed that an inclination angle (N) of the load-handling element (9) is determined by means of an inclination sensor (11a) and/or, as a state of the load-handling element (9), it is determined by means of a state sensor (11b) whether the load-handling element (9) is free or occupied, and that an evaluating unit (12) interacts with the control unit (15, 15a) in such a waythat, depending on the de
