The technical parameters are directly related to the service life of the crane

Bridge crane is widely used in processing workshop, assembly workshop, metal machinery workshop, maintenance workshop, various warehouses and other occasions. It can also be used for auxiliary lifting in metallurgical casting workshop. After considering the requirements of weather protection and improved design, it can be used in open air.

The camber of the main beam of the bridge crane is strictly required. It can be seen from the figure that there are multiple cambers of the main beam on the crane. Similarly, the camber value of the upper beam of the bridge crane is also an important technical parameter of the bridge crane, which directly affects the service life of the bridge crane. Therefore, it is very important to detect the camber of the main beam.

The camber of the main beam in the bridge structural steel also has a certain impact. According to the manufacturing process of the bridge crane bridge, the main beam, end beam, platform, trolley track and end beam connecting plate are combined into the bridge. Through many years of production practice, it is found that when the bridge crane is used for bridge structure construction, the dead weight of the main beam will inevitably cause low deflection. Due to the different support positions, The measured camber value of the main beam is also different due to the different downward deflection caused by the self weight of the main beam. Only when the bearing is placed below the mid span axis at both ends of the bridge can the measured camber value of the main beam be obtained. It is accurate and does not need to be modified. When the support is located at the broken beam of the bridge structure, two supports are often placed on the main beam in order to facilitate the insertion of the main beam end beam according to the assembly and welding process requirements of the main beam and end beam.
