Innovation of electric bridge crane control components

Mar 06, 2019
The positioning accuracy of electric bridge crane is an important requirement, most of them adopt the corner code disc, the gear chain, the laser head and the key hole to ensure. The positioning accuracy is usually 3mm, accuracy higher than 1mm requires an additional positioning system. 
In the improvement of electric bridge crane lifting speed and brake, the crane hook with low speed operation is accurately positioned, and the brake system of electric bridge crane is also controlled and monitored by micro processing.
The remote control system is used for electric bridge cranes and other electric hoist cranes, which is not only saves manpower, improves work efficiency, but also improves the operator's working conditions.
The distance detection and anti-collision device adopts a radio signal type anti-collision device. The anti-collision device is composed of a three-phase system for monitoring the driving distance of the front end of electric bridge crane. Generally, a signal warning is first issued, and then the vehicle speed is reduced to 50%. Finally, cut off the motor power and brake the crane.
