Description

Technical Field

[0002] The beam lifting machine is a gantry crane specially designed for bridge construction. The beam lifting machine is mainly composed of a main beam, a leg, etc. The components are connected by pins and high-strength bolts, which are easy to disassemble and transport. It is suitable for road and bridge construction units that often move. The existing beam lifting machine generally directly lifts heavy objects through steel wires and hooks, which has poor stability, is prone to shaking, and has poor fixing effect on the plate, which is troublesome to use. The patent publication number is CN209740508U, and the patent name is a patent disclosure of a high-stability beam lifting machine. The technical solution is convenient for fixing plates of different specifications. The lifting plate is connected with the steel wire rope, which is conducive to improving the stability during lifting. During transportation, two symmetrical steel wire ropes are fixed on the top of the lifting plate, which improves the stability to a certain extent. However, when the wind is strong, the steel wire rope is still prone to swinging to a large extent, affecting the stability of the lifting. Therefore, it is necessary to design a high-stability beam lifting machine that is convenient for fixing the plate and can lift and transport the plate more stably. Utility Model Content
