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

1. Programmable controller for automatic control. The operation of various mechanisms in cranes relies on program control devices, and nowadays cranes often use programmable controllers for control.

2. Automatic positioning device control. The automatic positioning of a crane is generally determined based on the usage environment and accuracy requirements of the controlled object to determine the mechanism form of the device. The automatic positioning device usually uses various detection components to cooperate with relays, contactors, or programmable controllers to achieve the goal of automatic positioning.

3. Ground operation, wired and wireless remote control of the hoist crane adopts ground control, and its key component is the manual button switch. Wired remote control is a method that uses dedicated cables or power lines as carriers to transmit signals through modems, achieving control with only a small number of channels. Wireless remote control utilizes contemporary electronic technology to transmit information in the form of radio waves or light waves as channels, achieving the purpose of control.

4. Correction and electrical synchronization of the large vehicle operating mechanism. Correction can be divided into manual correction and automatic correction. Manual correction is when the correction exceeds a certain value, the correction signal generator sends a signal, and the driver disconnects the motor on the leading leg side and connects the motor on the lagging leg side for adjustment. Automatic correction is when the deviation exceeds a certain value, the correction instruction generator issues instructions, and the system performs automatic correction. Electrical synchronization is commonly achieved in AC transmission using an electric shaft system with a balanced motor.

5. Crane electromagnet and its control circuit. Mainly providing DC power supply for electromagnets and fulfilling control requirements for suction and discharge. Its working mode is divided into two control forms: fixed voltage and adjustable voltage.
