Method and loading unit for damping loads which act in the case of overload

摘要

The invention relates to a method for controlling an energy absorber (2) on a loading unit (100) in the case of an overload event (63), and to a loading unit (100), wherein the energy absorber (2) of the loading unit (100) absorbs energy in the case of a one-time overload event. The energy absorber (2) acts between an accommodating unit (101) for accommodating objects (103) to be transported and a carrier device (102) for connecting to a means of transportation (50). An absorber force of the energy absorber (2) can be influenced by means of an electrically controllable magnetic field unit (16). Measured values (17-20) are recorded in succession over a loading process (80) of the loading unit (100) by means of a sensor device (61). An overload event (63) is determined if a measure (24) derived from the measured values (17-20) exceeds a predetermined threshold value (65). After an overload event (63) has started, a predicted load progression (70) of the loading unit (100) is estimated from a plurality of measured values (19-20) recorded substantially from the start of the overload event. A planed current-flow progression (71) for the magnetic field unit (16) is determined, by means of which planned current-flow progression the predicted load progression (70) is damped in dependence on time in such a way that a planned load progression that remains below a specified load limit (66) results. The current flow through the magnetic field unit (16) is controlled in dependence on time in accordance with the planned current-flow progression (71).
