With the development of related industries, the current crane is widely used in the way of wireless remote control. The use of remote control operation has the characteristics of improving working conditions and convenient operation. Especially in some slate production enterprises, wireless remote control has been widely used. It can avoid personal accidents caused by crane derailment or heavy objects falling, but when using wireless remote control, it is different from the traditional cable manual controller in safety use. Andit includes single speed crane control and dual speed crane control. Then, will you operate the crane wireless control unit safely? Now, we have a brief introduction to this, hoping to help you better understand the wireless crane control system.
The main points are as follows:
✉ How the wireless crane control unit works
✉ Requirements for operating the wireless crane control unit
✉ How to operate the wireless crane control unit correctly
After digital coding and encryption, the wireless remote controller of crane sends the operation instructions of personnel to the remote receiving system through wireless transmitter. The receiving system recovers the control command after decoding and conversion to realize the wireless control of driving. At the same time, it can realize driving wireless control in the environment of strong magnetic field, strong electric field and complex radio signal. 100% anti-interference capability. The wireless remote controller of crane can replace the handle or cam controller to carry out wireless remote control of traveling crane.
1. The crane with wireless remote control shall have various protection functions of the original crane, such as zero position, overcurrent, stroke and other protection functions.
(1) When the remote control adopts the non automatic reset control lever, all the control levers shall be set to the zero position before operation, and then the control command shall be issued.
(2) When the main controller and contactor are under control, the remote controller can be connected to the main power grid of the crane only when the main controller is at zero position.
(3) When the crane is cut off accidentally, the remote control shall stop working.
(4) After the power supply is restored, the remote control must be connected to the main power circuit of the crane through the correct starting procedure.
(5) When the power supply voltage of the remote controller is insufficient, it shall be able to send the stop command through the white control function.
2. The crane with wireless remote control shall be equipped with main contactor or air circuit breaker with voltage loss trip to cut off the main power supply of the crane. The power supply of all mechanisms must be led out from the output terminal of the main power contactor. The main power contactor or circuit breaker with voltage loss trip line shall be able to cut off the main power supply of all mechanisms and stop the operation of all mechanisms.
3. For the crane with wireless remote control, the crane shall be equipped with obvious remote control indicator light to indicate that the crane is operated by remote control.
4. When the crane is operated by remote control and cab at the same time, interlock between them shall be realized. The change-over switch must be set above the cab.
How can we operate it correctly and safely in our daily work?
1. The operator of the crane shall enter the main parts and safety devices of the crane before operation.
2. When the trolley or trolley of the crane is moving, when the grab is lifted, and there are people on the running line, a warning signal must be sent out.
3. Except for parking inspection, no one shall walk on the bridge or track.
4. When the crane needs to be overturned, the driver must drive at the lowest speed.
5. The driver should concentrate on his work. Eating, smoking, reading, magazines, chatting, sleeping and drinking after driving are forbidden in taxis.
It can be seen from the above introduction that the wireless crane control system can meet various production environments. This method can reduce labor force, save time, improve production efficiency and avoid personal injury and equipment loss due to misoperation to a certain extent. If you have any questions about the operation of wireless crane control system, please consult us in time, and we will be happy to answer them for you.
