Abstract (en)

[origin: WO2022073680A1] The invention relates to a method for controlling a hoist, such as a crane (1) or a cable excavator, wherein a load handling means (8) is mounted to a boom (3) in the manner of a pendulum, via a hoist cable (7), and the boom (3) and/or a trolley (9) which can travel on the boom (3) is moved by means of at least one drive device (6; 10), wherein, in order to move the load handling means (8), a target speed signal (v_target) is specified for the at least one drive device (6; 10), the natural frequency of the pendulum being filtered out of the specified target speed signal (v_target) by means of a filter (14) and the filtered target speed signal (v_target_transl) being used to control the at least one drive device (6; 10).
