What caused the single girder overhead crane to hit the top?

With the continuous development of the times, the manufacturing industry and the loading and unloading industry have developed more and more rapidly. At the same time, they have gradually shifted from outdoor to indoor, thus increasing the number of single-girder bridge cranes used.

The single girder overhead crane has its unique advantages. It can not occupy the main ground in the building, but this does not affect its operation with less materials and undecided forms. In addition, the price of single-girder bridge cranes is relatively cheap, and the operation is relatively simple and convenient. It can be said that in indoor cranes, single girder overhead crane account for 90%.

The bridge crane relies on the combination of the crane operating mechanism and the trolley operating mechanism to carry objects. For bridge cranes, the driving crane is the operating mechanism, and the lifting mechanism is used to lift the goods. In order that the crane can be used normally, pay more attention when placing the crane mechanism to ensure that it has sufficient strength and rigidity to ensure that its quality is guaranteed.

Maybe in the process of using the bridge crane, some friends will find that it will rise to the top. What caused this? Today we will give you a detailed introduction to the specific situation.

1. The negligence of the staff caused

Because the hook of the single girder overhead crane is pulled by the handle of the controller to pull, therefore, in the process of work, if the staff does not operate properly, there is no correct traction controller handle, for example, it is not pulled to zero. This will cause the hook to continue to rise, leading to a topping phenomenon, and sometimes even a safety accident.

2. Failure to check the stopper

The main function of the stopper of the single girder overhead crane is to control the hook during the lifting and lowering process of the hook. If the stopper is not carefully inspected during work, the joints are prone to adhesion. once adhesion occurs, the stopper is in a failed state, which causes the main hook to rise continuously. In the process of ascending, the steel wire rope could not withstand the impact of pressure, and the phenomenon of breaking occurred, which eventually caused the goods to fall. The consequences were unimaginable. Therefore, in the process of using single-beam bridge cranes, we must pay attention to whether the stopper is intact. If a malfunction occurs, it must be eliminated in time to avoid a safety accident.

3. No regular inspection and maintenance

For the older single-girder bridge cranes, we should do a good job of inspection and maintenance. Regularly check and troubleshoot, so as to avoid failures during use and cause safety accidents.

In short, when using a single girder bridge crane, the staff must carefully read its operating instructions, be familiar with the characteristics of the single girder bridge crane, have a certain ability to respond to emergencies, and operate strictly in accordance with the operating requirements to avoid The occurrence of the summit phenomenon.
