How to stop overhead crane from swinging?

In industrial workshops, Складишта, и градилишта, мостне дизалице are indispensable heavy-duty equipment, shouldering the important task of lifting and transporting materials. Међутим, a common and troublesome problem has always plagued operators—load swinging during crane operation. This swinging not only reduces the efficiency of material handling, extends the operation time, but also poses a serious threat to the safety of on-site personnel, опреме, and goods. Тако, how to effectively stop overhead crane from swinging? Today, we will explore the solutions to this problem, with a focus on the crane anti-swing system developed by Weihua, a leader in the crane industry.

Why Do Overhead Cranes Swing?

Before exploring the solutions, it is necessary to understand the root cause of overhead crane swinging. In essence, the swinging of the crane load is a kind of pendulum motion. When the crane starts, престани, accelerates, or decelerates, the load will generate inertial force due to the change of motion state. Under the action of this inertial force, the load hanging on the кука за кран will swing back and forth around the hook point. In addition, factors such as uneven track, wind load (especially for outdoor cranes), and improper operation of the operator will also exacerbate the swinging of the load. The heavier the load and the longer the lifting height, the more obvious the swinging phenomenon, and the greater the potential safety hazard.

Traditional Methods to Reduce Crane Swinging

In the early days, the industry mainly relied on two methods to reduce overhead crane swinging. The first is to improve the operator’s skill level. By requiring the operator to master the precise operation skills of starting, stopping, and moving at a constant speed, the impact of motion state changes on the load is minimized. Међутим, this method has high requirements for the operator’s experience and concentration, and it is difficult to avoid swinging completely, especially in the case of complex working conditions. The second is to install mechanical buffering devices, such as shock absorbers and limiters. These devices can play a certain role in buffering when the crane starts and stops, but they can only passively reduce the swinging amplitude, and the effect is limited for the swinging caused by inertial force during movement.

Core Solution: Weihua’s Developed Crane Anti-Swing System

With the development of automation and intelligent technology, the active crane anti-swing system has become the most effective way to solve the problem of crane swinging. Among them, the anti-swing system independently developed by Weihua Group has won wide recognition in the industry due to its advanced technology, stable performance, and wide applicability.

Working Principle of Weihua Crane Anti-Swing System

Weihua’s crane anti-swing system is based on advanced intelligent control algorithms and high-precision sensing technology, realizing real-time monitoring and active control of load swinging. The system is mainly composed of three core parts: сензори, controllers, and execution mechanisms.

Прво, the high-precision sensors installed on the crane’s trolley and hook real-time collect data such as the position, speed, acceleration of the trolley, and the swinging angle of the load. These data are transmitted to the intelligent controller at high speed. Then, the controller uses the self-developed anti-swing algorithm to analyze and calculate the collected data in real time, predict the swinging trajectory of the load, and generate the optimal control signal. Finally, the execution mechanism (such as the frequency converter of the crane’s driving motor) receives the control signal and adjusts the running speed and acceleration of the trolley and bridge in real time, offsetting the inertial force generated by the load through reverse control, thereby realizing the purpose of quickly suppressing swinging.

It is worth mentioning that Weihua’s anti-swing algorithm has strong adaptability. It can automatically adjust the control parameters according to different working conditions such as load weight, висина подизања, and running speed, ensuring the anti-swing effect under various complex scenarios. Whether it is the rapid start and stop of the crane or the long-distance movement of the load, the system can keep the load in a stable state.

Advantages of Crane Anti-Swing System

Compared with traditional crane anti-swing methods and other similar products on the market, Weihua’s crane anti-swing system has obvious advantages:

• 1. High anti-swing efficiency: The system can quickly suppress the load swinging within 2-3 cycles, even in the case of sudden start and stop, the swinging amplitude can be controlled within 5%, which greatly improves the handling efficiency.
• 2. Strong stability and reliability: The system uses high-quality sensors and controllers, and has undergone strict environmental adaptability tests (висока температура, low temperature, влажност, dust, итд.), ensuring stable operation in harsh industrial environments. At the same time, the redundant design of the system ensures that even if a single component fails, it will not affect the basic operation of the crane.
• 3. Easy to operate and low maintenance cost: The system is integrated with the crane’s control system, and the operator only needs to operate the crane according to the normal process, and the anti-swing function can be automatically activated without additional complicated operations. In addition, the system has a self-diagnosis function, which can timely detect potential faults and remind maintenance personnel, reducing maintenance costs and downtime.
• 4. Wide applicability: The system can be applied to various types of overhead cranes, порталне дизалице, jib cranes, итд., and can be customized according to the specific parameters and working conditions of the crane, meeting the needs of different industries such as machinery manufacturing, automobile production, port terminals, and warehousing and logistics.

Application Effects of Weihua Anti-Swing System

Up to now, Weihua’s crane anti-swing system has been widely used in thousands of enterprises at home and abroad. Taking a large automobile manufacturing plant as an example, after installing Weihua’s crane anti-swing system on the overhead cranes in the stamping workshop, the load swinging during the transportation of stamping parts was completely controlled. The handling time of a single batch of parts was shortened by 30%, and the occurrence of safety accidents caused by swinging was reduced to zero. The relevant person in charge of the enterprise said that the application of Weihua’s anti-swing system not only improved the production efficiency, but also reduced the loss of goods and equipment, bringing significant economic benefits.
