Crane anti-swing and anti-swing automatic positioning control system

Every crane has the problem of load swing, and crane load swing of machine damping is a big topic that has been studied for decades, even hundreds of years.

During the operation of the 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 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. Crane load swing is the inherent phenomenon of crane moving materials.

Since the invention of cranes, preventing and eliminating the swaying of 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 crane load swing.

Benefits of installing anti-swing control systems

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

Anti-swing Control Scheme of Crane

Close loop control: Measuring load swing angle, complex feedback control, high price.

Open loop control: Only need to control the speed of the crane and trolley, simple and effective, low price.

Crane with anti-swing control function can be widely used in various industrial fields, including mechanical manufacturing workshop, assembly workshop, garbage disposal plant, steel plant, power plant, shipbuilding plant, construction site, railway, container terminal, paper industry and metallurgical industry.

Based on the realization of electric anti-swing control, the electric anti-swing automatic positioning control technology is further developed, which can transform the crane into a lifting robot and make the crane like a robot. The load is accurately and periodically transported to any designated position at a specified point along the specified line, and during and after arrival at the specified position, the load does not produce any sway, thus overcoming all necessary for the automation of the material handling height, It is also a major technical difficulty. The successful development and wide application of crane electrical anti-swing control technology will change people cognition of crane load swing problem all the time. It will be an important milestone in the history of technology progress in material handling field.
