METHOD AND SYSTEM FOR CONTROLLING CRANE ROTATION

摘要

Disclosed are a method and a system for controlling crane rotation. The method and the system comprise: determining the rotational acceleration or resultant rotational force of the pendant ballast when the crane is rotating (S31); when the rotational acceleration is greater than a preset value thereof, or when the resultant rotational force is greater than a preset value thereof (S33), reducing the rotary speed of the rotational motor within a determined time period so as to reduce the rotational acceleration of the crane (S35). Using the method and the system aids in preventing the destructive influence of the kinetic energy of the pendant ballast on the overall or partial stability of the crane.
