METHOD FOR CONTROLLING THE SKEW OF AN OVERHEAD OR GANTRY CRANE Russian patent published in 2022 - IPC B66C9/16 

FIELD: overhead cranes.

SUBSTANCE: invention relates to overhead cranes. When determining the skew of the crane, the determination of the skew of the crane is used as a function of the delay time for the occurrence of the event of passing the reference point from one side and the other from the right and left rails. Moreover, the reference points are located on an axis perpendicular to the axis of the rails, and the distance between these generating axes can be either different or the same. When detecting and fixing the amount of skew in the form of the value of the delay in passing the reference points by the right and left sides of the crane bogie, in the event of receiving commands to increase the speed, it is relatively easy to reduce the skew of the crane by delaying the execution of the sequence of commands to increase the speed by the drive device of the advanced side by the amount of delay in passing the reference points right and left sides of the crane trolley.

EFFECT: improved quality of crane skew control with simultaneous reduction of the complexity of its implementation.
