The important load-bearing components of bridge cranes mainly include the following aspects:

Main beam: The main beam is the main supporting structure of a bridge crane, usually a large steel structure or welded steel plate. It is responsible for supporting and carrying the self weight of the bridge crane, the weight of the lifting object, and various motion loads. The design of the main beam needs to have sufficient strength and stiffness to ensure the stability and safety of the crane. In bridge cranes, the weight of the main beam often accounts for a large proportion of the entire lifting machinery, so the optimized design of its structure is crucial for improving the overall performance of the crane.

Large and small wheels: Large and small wheels are important moving parts of bridge cranes. The large wheels are operated by the crane operator to carry the weight of the lifted object and some of their own weight; The small wheels are responsible for massive translational motion. These two components require regular maintenance and inspection to ensure that they can operate normally and withstand the corresponding loads.

Rack and gear: Rack and gear are key components used in bridge cranes to drive the operation of large and small wheels. They achieve smooth movement of the crane through precise meshing and transmission. These components require regular inspection and maintenance to ensure their accuracy and normal operation, avoiding malfunctions and unexpected situations.

Walking mechanism: The walking mechanism is an important component of the bridge crane, responsible for supporting and maintaining the smooth operation of the crane. It includes components such as gear reducers, electric motors, walking wheels, and racks. The performance of the walking mechanism directly affects the operational stability and safety of the crane, therefore regular inspection and maintenance are required.

Hook and other lifting equipment: Hook is the main lifting equipment of bridge crane, used for hanging and moving goods. It is usually connected to the main trolley or end trolley through a sling or chain. In addition to the hook, it may also include other lifting equipment such as electromagnetic suction cups, grab buckets, etc. These devices also bear important loads and require regular inspection and maintenance.

Electrical system: Although the electrical system itself is not a direct load-bearing component, it plays a crucial role in the operation of the crane. The electrical system includes control cabinets, cables, switch buttons, limit switches, and other electrical equipment used to control various actions and functions of the crane. The stability and reliability of the electrical system directly affect the operational efficiency and safety of the crane.
