Electrical Maintenance of Single Girder Overhead Crane

In order to ensure the reliable and safe operation of single girder overhead crane. It is necessary to formulate an electrical equipment maintenance system that meets the requirements of "GB6067-85". And be familiar with the causes of various failures of the equipment and the methods to eliminate them.

The maintenance of the main electrical equipment is described below.

In order to increase the service life of crane electrical equipment, the contactors in the electrical equipment control box should be kept clean to prevent leakage breakdown and short circuit (current does not pass through the electrical appliances, directly connected to the power supply poles) and other phenomena.

When the electrical cable is used to conduct electricity. The corner rust and dirt on the slide rail of the trolley should be removed at any time to keep the traction pulley running normally.

Track inspection: mainly observe whether the track is straight, whether the pressing plate is firm. And whether there is any looseness. If you find that the track is stuck when the trolley is walking, you should try to correct the track or adjust the wheels.

Safety operating rules for single-beam cranes: Hanging objects are not allowed to stay in the air for a long time. When hoisting objects, staff are not allowed to leave their jobs.

It is strictly forbidden to operate after drinking, and to chat while working. After the work is completed, the single girder overhead crane should be moved back to the left side of the gate and parked. And the operation button switch should be hung at the designated position.

When the operation button switch is hung, pay attention to this. How to hang it before taking it down, and how to hang it when putting it back. This is to prevent rainwater from flowing into the button.
