How to adjust the deformation of the track of the bridge crane trolley

The lifting mechanism of the double girder bridge crane is installed on the trolley above the two main girders, and the trolley runs left and right along the track above the main girder to complete the movement of heavy objects in the space parallel to the main girder. If the crane is used for a long time, it may encounter the problem of deformation of the trolley track. How should the deformed trolley track be adjusted?

For severely deformed trolley tracks, we recommend replacing the tracks directly. If the deformation is not serious, you can cut off the track pressure plate with oxygen cutting, lay out the span of the trolley with a ruler, then use a jack to correct the track, and fix it with the pressure plate welding.

The trolley track of the double-beam bridge crane is generally welded and installed on two parallel main beams, so the deformation of the track is basically rare. If there is deformation, the company's best to check the lower deflection and side camber of the main girder Whether it meets the standard. Because the track deformation is likely to be caused by the deformation of the main beam.

After the trolley track is deformed, it must be adjusted in time to avoid more serious problems such as the trolley gnawing and climbing the track.

In addition, the crane track cannot be corrected with flames. When dealing with the problem of track deformation, you must abide by the relevant standards and regulations.
