Method for determining at least one pendulum angle and/or angle of rotation of a load attached to a crane with at least one rope-based fastening and method for damping the pendular movements and/or rotary movements of the load

摘要

The invention relates to a method for determining at least one pendulum angle and / or angle of rotation of a load received on a crane via at least one cable-like fastening means, the crane having a boom and a trolley, to which the load is attached via the at least one cable-like fastening means, and on the crane at least one optical detection device for detecting a pendulum angle and / or angle of rotation of the load is provided, wherein by means of the at least one optical detection means a pendulum angle and / or rotation angle of the load is detected, it being assumed that the detected pendulum angle and / or Angle of rotation is associated with a conditional by the at least one optical detection device systematic error, and the value of the systematic error, with which the detected pendulum angle and / or angle of rotation is afflicted, is determined. Moreover, the invention relates to a method for damping pendulum movements and / or rotational movements of the load and a crane.
