The Importance and Influence of the Main Beam Convex of Bridge Crane

Bridge cranes are widely used in metalworking workshops, assembly workshops, metal workshops, maintenance workshops, various warehouses and other occasions. They can also be used in metallurgy and foundry workshops for auxiliary lifting. After considering the requirements of wind and rain protection and improving the design, it can be used in the open air.

The arching degree of the main girder of the bridge crane is strictly required. It can be seen how heavy the main girder camber is for the bridge crane. The same value of the girder value of the girder crane is an important technical parameter of the bridge crane. The service life of the bridge crane. Therefore, the detection of the main beam crown is very important work.

In the bridge structure steel, the main beam self-weight multi-main beam arch degree also has a certain influence. According to the bridge crane bridge manufacturing process, the main beam, the end beam, the walking platform, the trolley track and the end beam link plate components are combined into a bridge frame. Through years of production practice, it is found that when the bridge crane is in the bridge structure, the self-weight of the main beam will inevitably cause the lower deflection, and the lower deflection value caused by the self-weight of the main beam is different due to the difference of the position of the bracket. The degree of camber on the beam is also different. Only when the bracket is placed under the centerline of the span of the bridge, the measured camber value of the main beam is accurate and does not need to be corrected. When the bracket is located in the bridge structure diagram in the broken beam and the bridge structure is actually carried out, according to the requirements of the assembly process of the main beam and the end beam assembly, in order to facilitate the insertion of the end beam of the main beam, the two brackets are often placed on the main beam.
