Abstract

An energy absorber is controlled in an overload event to absorb potentially damaging energy. The energy absorber acts between a receiving unit for receiving objects for transporting and a carrier device that connects to a transporter. An absorber force can be influenced by an electrically controlled magnetic field unit. Measurement values of loads acting on the loading unit are captured sequentially and an overload event is determined if a measure derived from the measurement values exceeds a predetermined threshold value. After the onset of an overload event a prognosticated load curve of the loading unit is assessed from a multitude of measurement values captured from the onset of the overload event. A planned power flow curve for the magnetic field unit is determined and the load curve is damped time-dependent so that a planned load curve ensues which remains beneath a predetermined load limit.
