Crane Knowledge: Overhead Crane Anti-swinging Systems

 During overhead crane operation, swing-and-sway will be produced to the loads lifted, due to the overhead crane and hoist staring, speeding up, and braking, which is called pendulum effect. When the overhead crane manufacturer 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.

Every overhead crane has the problem of load swing, and the problem of machine damping is a big topic that has been studied for decades, even hundreds of years.
During the operation of the overhead crane, the load will appear an annoying swing phenomenon because of the acceleration and deceleration of the trolley. This kind of load swing phenomenon limits the improvement of overhead crane working efficiency. The rocking of the load also causes hidden danger to the load itself, the surrounding goods, and the personal safety of the field operators. Load swing is the inherent phenomenon of overhead crane moving materials. Since the invention of overhead cranes, preventing and eliminating the swaying of overhead crane loads has always been a major technical problem that people are eager to solve. The progress of modern electrical control technology, especially the progress of the application of advanced programmable controller and variable frequency speed control technology, provides a historical opportunity to solve the problem of overhead crane load swing.

Benefits of installing anti-swing control systems

  • a. It can greatly improve the production efficiency of overhead crane use, improve the safety of overhead crane use, and reduce the risk of damage to cargo and injury to personnel.
  • b. It’s possible to make a high degree of automation of various production processes requiring overhead crane equipment.
  • c. Reduce the point operation of the overhead crane and prolong the service life of the overhead crane.
  • d. Improve the safe running Speed of Overhead crane and further improve the production efficiency.
  • e. Easy to master and operate, reduce the training time for the operation staff, reduce the labor intensity of the operation staff
