Single beam crane is a small machine. If an accident occurs at high altitude, it will lose a lot. The operation of single beam crane is controlled by various controllers. Once the controller fails, it will not only damage the equipment, but also endanger personal safety.
Therefore, we should calmly solve the fault of the crane controller to avoid major accidents. The fault of the crane controller is usually caused by the failure of the contactor core in the electrical control circuit, which also reminds us that no matter how busy the operation is, we must pay attention to the operation of the equipment and stop the operation immediately in case of abnormalities. If the controller of the crane fails, the lifting mechanism must be started repeatedly to control the hook so that the hook cannot fall freely.
The operator shall also immediately press the emergency switch to cut off the power supply to avoid safety accidents. Meanwhile, the maintenance personnel shall find out the cause of the fault as soon as possible and replace the damaged parts to restore the normal operation of the crane.
