Application of Industrial Wireless Remote Control System on Bridge Crane

With the development of related industries, bridge crane has been widely used in metallurgical industry, and the bridge crane pendant controls have also been widely used. This method belongs to the pedant crane control. Due to the characteristics of the industry, the operating conditions of the operator in the cab of the bridge crane are very poor, so in some aspects, it can not effectively guarantee the personal safety of the driver. However, with the development of wireless remote control technology, especially the use of advanced digital processing technology and radio communication technology, the remote control system has been improved in security, reliability and other aspects. Using wireless remote control to operate the suspension control of bridge crane has gradually become the standard process of crane equipment design and manufacturing. Now, we will give you a brief introduction of this process, hoping to help you better understand the wireless remote control of the bridge crane pendant controls.

 

The main points are as follows:

✉ Type of bridge crane pendant controls wireless remote control

✉ Wireless remote control mode for bridge crane pendant controls

✉ Selection of radio remote control

✉ Conclusion

 

Type of bridge crane pendant controls wireless remote control

According to the national standard of China's mechanical industry, the wireless remote control device is mainly divided into infrared remote control and radio remote control. The infrared remote control is mainly used in the work place where the visibility between transmitter and receiver is good and the distance is relatively close, so the application of infrared remote control is limited; the radio remote control is the main form of crane remote control and the leading product in practical application.


Wireless remote control mode for bridge crane pendant controls

The basic control mode of industrial wireless remote control system is mainly divided into one to one mode, many to one mode and many to many modes.

 

(1) One to one mode, that is, a transmitter corresponds to a receiver. According to different applications, there can also be many to one and one to many control modes.

 

(2) Many to one control means that multiple transmitters correspond to one receiver, that is, multiple transmitters control one crane in time. For example, when the installation position of the crane is high, in order to improve the operation accuracy, several working platforms should be divided in the vertical direction. When the lifted object reaches a working platform, the transmitter bracket of the working platform is controlled by the conversion of the main transmitter. Control the crane.

 

(3) Many to many control mode refers to that one transmitter corresponds to multiple receivers, that is, one receiver controls multiple cranes at the same time. This control mode is very useful when handling, assembling or servicing large or special objects, such as using a transmitter to synchronously control two cranes to handle rails.

 

Selection of radio remote control

In addition to the difference between the control mode and the output mode, there are many kinds of radio remote control, and the control points of the remote control itself are also very important. Generally speaking, one button on the transmitter occupies one control point; two switch buttons (self reset or not) occupy one control point; one pair of two-way two speed buttons occupy three control points; for the remote control (corresponding to the main controller or cam controller of analog multi gear), the control point is the original control gear plus one control point; emergency stop switch and change The key that the feeder closes does not occupy the control point. According to the above basic principles, and referring to the actual operation requirements of the crane for remote control transformation, we can determine the specific model of transmitter and receiver.


Conclusion

Because of the use of wireless remote control to the bridge crane pendant controls, the operator only needs to carry a light transmission system, walk freely and select the best visual position to operate, thus eliminating the accident hidden danger caused by blurred vision, the past bad environment or improper command and coordination to ensure safe operation; because of operation, mooring and hook, it can be operated by It can save human resources greatly by one person alone without other people's command; moreover, in this daily operation, the operator can judge independently, which can significantly improve the accuracy and consistency of the operation compared with the previous, thus greatly improving the production efficiency. If you have any questions about the bridge crane pendant controls , please consult us in time.
