Principle of anti-sway control of European-style cranes
- Apr 05, 2015 -

The objects hanging under the industrial cranes will be swayed by the operation of the car (or the cart), and only very experienced operators will be able to control the stop without swinging without the crane swinging system. Because there is no need to wait for the material to stop swinging, and can be accurate positioning, so the industrial crane's swing-proof system can obviously improve the work efficiency.

Anti-sway control is the use of pendulum principle, through the modification of the electrical control system to the speed command signal and continuously limit the swing. The swing angle is calculated by checking the lifting height of the hook, and then the pendulum angle is offset by a given acceleration and deceleration. When the object reaches the set speed or stops swinging very little or basically does not swing.
