Maintenance mode of main beam and end beam in the steel structure of bridge crane

the steel structure of bridge crane is mainly composed of main beam, end beam, handrail, walking platform, track, cab and other components

I. main beam. The general bridge crane is composed of two main beams, two end beams and some parts. The bridge has a truss real-time data collection and testing system. During the experiment, the friction force is transmitted to the pressure sensor main beam and box main beam through the lever

the main beam bears the weight and external load of the trolley. Therefore, it must have sufficient strength, static stiffness and dynamic stiffness to ensure that the main beam will not deform within the allowable range of elastic deflection under the specified load

through the mechanical drum

II. End beam. The end beam of the bridge crane is the main load-bearing member. In the main detection mechanism, the temperature requirements of the mechanics room are not considered. The beams are connected by welding or bolts, and the end beam is mostly welded into a box structure with steel plates. The wheel set of the crane is installed under the end beam to bear all the vertical loads of the crane

on the old bridge crane, the wheel set of the crane is directly supported under the end beam by sliding bearings, while on the new bridge crane, the wheel set of the crane is bolted to the end beam by angular bearings, which is designed to facilitate maintenance

parameter value and operation of universal testing machine
