Background

Railway freight cars sometimes need to be hoisted, such as loading the railway freight cars into ships, resetting derailed vehicles, and the like. The lifting lug is welded on the wagon body and is used for hoisting the railway wagon. The body of a railway wagon is connected to the bogie via a bolster, which is the main load-bearing part of the vehicle. The force transmission route of the weight of the cargos on the vehicle is as follows: other vehicle body components-bolster-bogie-track. To ensure the safety and stability of the lifting, the lifting lugs are usually arranged on the sleeper beam.

For a vehicle with a floor, the lifting lugs are typically provided on the side rails outside the bolster. Vehicle design is typically performed with a vehicle width that must be less than the vehicle clearance dimension of the user. When the vehicle has a floor and the vehicle width is very close to the vehicle limit, no lifting lug can be arranged on the outer side of the sleeper beam. In the case where the vehicle width cannot be shortened, the shackle may be provided only at the end of the vehicle. However, the weight of the railway freight car is heavy, and if the lifting lug is arranged at the end part of the car, particularly when the car with goods is lifted, the bending moment in the middle of the car is large, and the stress of the structure in the middle of the car may exceed the allowable stress of the car material, thereby causing damage to the car body. Therefore, in the prior art, due to the blocking of the floor, the arrangement of the lifting lug of the railway wagon with the floor is limited, and a plurality of troubles are caused.
