[0002] As we all know, cranes are needed in railway construction. When cranes are lifting large equipment, they must maintain balance and prevent the equipment from being scratched by the lifting ropes. In addition, they must minimize the deformation of the equipment during the lifting and handling process. Therefore, a balanced lifting beam is needed during the lifting process.

[0003] As the prior art of the balanced hanging beam, the Chinese patent publication (publication number: CN203903772U) discloses a multifunctional crane balanced hanging beam, wherein a hanging ring is fixed on the main body of the balanced hanging beam, and three moving units are installed on the main body of the balanced hanging beam, and each moving unit is connected to a hook, and the moving unit is positioned by a positioning block on the main body of the balanced hanging beam, and bracket blocks are fixed on both sides of the main body of the balanced hanging beam, and the bracket is flexibly connected to the main body of the balanced hanging beam through pins, and the main body of the balanced hanging beam is marked with scales in the horizontal direction, and the hook is provided with a buckle for clamping the positioning block. Compared with the original technology, it has multi-gear adjustment, overcomes the defect that it can only be used on fixed-size components, realizes the function of one device for multiple uses, and reduces material costs. Secondly, through the use of the moving unit, the hanging point can be quickly changed without disassembling the buckle, which is convenient for operators to use and improves the efficiency of hoisting;

[0004] However, when the crane balance beam in the prior art is in use, the support blocks used to support the beam body placed on the ground lack a buffering structure, which causes the support blocks to collide with the concrete floor when the beam body falls, and easily causes damage to the concrete floor. Therefore, a balance beam for a railway crane is proposed. Summary of the invention
