Application of anti sway technologies in bridge crane

When the overhead crane is in normal operation, the acceleration and deceleration caused by the starting and braking of the crane and the trolley will cause a certain swing of the flexible suspension load, which will directly affect the production efficiency of the crane. For the bridge crane with frequent operation, it is urgent to reduce the swing time of the load and improve the working efficiency. In addition, the swing of the load will also cause great safety risks to the staff, equipment and crane itself. In order to ensure the safety of overhead crane, anti sway technology is usually used. 

The commonly used anti-sway methods for bridge cranes mainly include manual, mechanical and electrical. Among them, electrical anti-sway and inverted eight character anti-sway of mechanical anti-sway are better solutions.

The electric anti swing system has the following advantages: reduce the swing amplitude by more than 90%, improve the production efficiency by more than 30%; be able to accurately locate in a short time, reduce the working intensity of the operator; easy to operate, reduce the impact, prolong the service life of the crane; improve the use safety. The biggest advantage of the inverted eight shape anti sway system is that it can prevent two-way swing in the operation of crane and trolley, and the center of the tension wire rope is close to the load center. In practical application, the superiority of the anti swing function is also proved. 

A good anti-sway system can have a good anti-sway effect, which can improve the production efficiency of the overhead crane and reduce potential safety hazards in the production process. Manufacturers should determine the selection scheme according to their own needs.
