During crane operation, swing-and-sway will be produced to the loads lifted, due to the crane machine (https://www.craneskit.com/) and hoist staring, speeding up, and braking, which is called pendulum effect. When the crane reaches the desired place, the lifted loads swings and sways, making the unloading impossible at the moment, lengthening the working cycle, and eventually lowering the production capability. In order to lower the swings and sways, the following anti-swinging system is recommended for your reference.
Manual anti-sway system
The manual anti-sway methodology is mainly relied on the operation of crane operator. When the trolley reaches the desired place, the crane operator immediately conduct the operation reversely which make the lifting devices moving reversely to reduce the impact of the swings caused by braking.
Advantages: Reduce swing immediately, improving crane working efficiency.
Disadvantages: Server impact will be produced to the electric components, and lower the working life, therefore, it is not recommended for long term use.
Rigid guide pillar anti-sway system
The use of rigid guide pillar instead of steel wire rope is the most effect way to prevent swings and sways, which can improve the crane performance effectively.
Advantages: Effective to reduce swing, improving crane working efficiency.
Disadvantages: Rigid guide pillar is designed completely, and the crane weight will be increased due to the weight of rigid guide pillar, the lifting height will be reduced.

Hydraulic cylinder-driven anti-sway system
The hydraulic cylinder-driven anti-sway methodology is used to control and reduce the impact of the swings and sways produced which cannot prevent the happening of the swings and sways. The system is usually used in the shore crane, with complicated structures and high required to maintenance.
