Importance and Influence of Main Girder Camber of Overhead Crane

Views:0     Author:Site Editor     Publish Time: 11-10-2021      Origin:Site

Overhead cranes are widely used in metalworking workshops, assembly workshops, metal mechanism workshops, maintenance workshops, various warehouses and other occasions. At the same time, the bridge crane can also be used for auxiliary lifting in metallurgy and foundry workshops. After considering the requirements of wind and rain and improving the design, it can be used in open air.

The camber of the main girder of the overhead crane is strictly required. It can be seen that the camber of the main girder is very important for overhead cranes. The camber of the upper beam of the overhead crane is an important technical parameter of the overhead crane, which is directly related to the service life of the overhead crane. Therefore, the detection of the main beam's camber is a very important work.

The self-weight of the main girder in the bridge structure steel also has a certain influence on the camber of the main girder. According to the overhead crane manufacturing process, the main girder, end girder, walking platform, trolley track, main and end girder and other components are combined into the bridge. Through many years of production practice, it is found that the weight of the main girder will inevitably cause downward deflection when the bridge crane is in the bridge structure. Due to the different positions of the brackets, the downward deflection caused by the weight of the main girder is different, and the upper camber of the main girder measured from this is also different. Only when the bracket is placed under the centerline of the span at both ends of the bridge, the measured upper camber of the main girder at this time is accurate.
