How to prevent overhead bridge crane wheel gnawing rail
time:Oct 19,2016
Overhead bridge crane wheel occur gnawing rail, should carefully check the situation of eating rail, measure the components size, comprehensive analysis to determine the reasons for gnawing rail, develop a repair program. At the same time, should take the correct measures to prevent the occurrence of gnawing rail.
1. In accordance with the technical requirements, adjust overhead bridge crane rail to ensure elevation, span, linearity, etc. are in line with the requirements, regularly check the bolts are tightened.
2. Separate drive overhead bridge cranes, if crane body skew, will make the front drive wheel diameter reduce, or the back drive wheel diameter becomes larger, which requires the correct the walk bridge frame.
3. The bridge frame may deform because of the overhead bridge crane gnawing rail, need repair. Flame correction method is relatively laborious, it is appropriate to adjust the wheel position to reduce the wheel span, the diagonal span error caused by bridge frame deformation.
4. Adjust the crane traveling transmission. In the transmission part of the traveling mechanism, the wear and tear parts may cause error, should adjust the connection part, repair or replace parts if necessary.
