If overhead bridge crane wheel occurre eating rail, must carefully check the situation, measuring the components size to determine the reasons for eating rail, develop a repair program. At the same time, should take the correct measures to prevent the eating rail.
1. Adjust the overhead bridge crane rail in accordance with the technical requirements, ensure elevation, span, linearity, etc. meet requirements, regularly check the bolts are tightened.
2. Overhead bridge cranes are driven by separate driving, if the crane deflect, may cause the front driving wheel diameter reduce or the back driving wheel diameter to be larger, which requires adjust the bridge frame automatic correction.
3. The bridge frame may appear deformation caused by the gnawing rail, should adopt flame correction method to repair, adjust the wheel position to reduce the wheel span, the diagonal span error cause by deformation of the bridge frame.
4. Adjust the overhead bridge crane transmission. Operating mechanism transmission parts will appear errors due to components wear and tear, can adjust connection part. If necessary, should repair or replace new parts.
