Crane control system

The crane control system is very important, so our Shandong single beam crane manufacturer will introduce the crane control system to you, hoping to help you.

1. PLC automatic control. The operation of each mechanism of the crane depends on the program control device. Now the crane is mostly controlled by the programmable controller.

2. Automatic positioning device control. The automatic positioning of crane generally determines the mechanism form of the device according to the use environment and accuracy requirements of the controlled object. The automatic positioning device usually uses various detection elements to cooperate with relays, contactors or programmable controllers to achieve the purpose of automatic positioning.

3. Ground operation, wired and wireless remote control hoist crane adopts ground control, and its key component is manual button switch. Wired remote control is a method that uses a special cable or power line as the carrier to transmit signals with a modem, so that control can be achieved with only a few channels. Wireless remote control uses modern electronic technology to transmit information in the form of radio waves or light waves, so as to achieve the purpose of control.

4. Rectification and electrical synchronization of crane operating mechanism. Deviation correction is divided into manual deviation correction and automatic deviation correction. Manual deviation correction refers to that when the deviation correction exceeds a certain value, the deviation correction signal generator sends a signal, and the driver disconnects the motor at the leading outrigger side and connects the motor at the lagging outrigger side for adjustment. Automatic deviation correction is that when the deviation exceeds a certain value, the deviation correction instruction generator sends instructions, and the system automatically corrects the deviation. In AC drive, electrical synchronization is usually realized by electric shaft system with equalizing motor.

5. Crane electromagnet and its control circuit. It mainly provides the DC power supply of electromagnet and completes the control requirements (suction and discharge). Its working mode is divided into two control forms: constant voltage and adjustable voltage.
