In the process of using a single girder bridge crane, some friends will find that they will appear to peak. Which fators may cause single girder crane to hit roof? Today, Nucleon crane engineer provides a detailed introduction for everyone. For details, please read the following:
1. The negligence of the staff leads
Because the single-girder bridge crane's hook operation is pulled by the controller's handle pull, therefore, in the course of the work, if the staff does not operate properly, there is no correct traction controller handle, for example did not pull it to zero Bit, this will cause the hook to continue to rise, resulting in the peak phenomenon, and sometimes even cause safety accidents.
2. Not do check the limiter work
The main function of the stopper of the single beam bridge crane is to control the hook during lifting and lowering of the hook. If you do not perform a careful inspection of the stopper during work, the connector is prone to sticking. Once blocking occurs, the limiter is inactive, causing the main hook to rise. In the process of ascent, the steel wire rope could not withstand the pressure collision, resulting in a fracture phenomenon, which eventually caused the cargo to fall. The consequences were unimaginable. Therefore, in the process of using a single-girder bridge crane, we must pay attention to whether the stopper is intact. If there is a failure, it should be promptly excluded so as to avoid a safety incident.
3. There is no regular inspection and maintenance
For older single-girder bridge cranes, we should do inspection and maintenance work. Regularly check and troubleshoot, so as to avoid failure during use and cause safety accidents.
In short, when using single-girder bridge cranes, the staff must read their operating instructions carefully, be familiar with the characteristics of single-beam bridge cranes, have a certain ability to respond to unexpected situations, and operate strictly in accordance with operational requirements.
