Matters Needing Attention
In the operation process of bridge crane, its control system plays a crucial role, in addition to the common CAM controller control and master command controller control these two control forms, bridge crane also successfully realized automatic control, thus improving the performance of each action.
The automatic control system of bridge crane includes the automatic control of programmable logic controller, the control of automatic positioning device, the rectification and electrical synchronization of vehicle operating mechanism, the electromagnet and its control circuit, and the ground control.
The operation of each mechanism of bridge crane depends on the program control device. While its automatic positioning is generally determined according to the operating environment and accuracy requirements of the controlled object. The automatic positioning device usually USES various detection components to cooperate with relays, contactors or programmable controllers to achieve the purpose of automatic positioning.
The deviation correction and electrical synchronization of the operating mechanism of the truck in the bridge crane are divided into artificial deviation correction and automatic deviation correction. When the deviation correction exceeds a certain value, the signal generator will send a signal, and the driver will disconnect the motor on the side of the leading leg and connect the motor on the side of the lagging leg for adjustment. When the deviation exceeds a certain value, the deviation correction instruction generator will issue an instruction and the system will automatically correct the deviation. Electrical synchronization is in the ac drive, usually with a balanced motor shaft system to achieve electrical synchronization.
Some cranes use ground control, the key component is the manual button switch, the cable remote control is through a special cable or power line as the carrier body, the signal with a modem transmission mode, to achieve only a few channels can achieve control method. Wireless remote control USES modern electronic technology to transmit information in the form of radio waves or light waves to achieve the purpose of control.
