Description

Technical Field

[0002] Crane refers to a multi-action lifting machine that can lift and carry heavy objects vertically and horizontally within a certain range. It is also called overhead crane, overhead crane, and crane. Some lifting equipment has the working characteristic of intermittent movement, that is, the corresponding mechanisms of taking materials, moving, unloading, etc. work alternately in one working cycle. The development and use of cranes in the market are becoming more and more extensive.

[0003] The crane mainly includes the lifting mechanism, operating mechanism, luffing mechanism, slewing mechanism and metal structure. The lifting mechanism is the basic working mechanism of the crane, which is mostly composed of a hanging system and a winch, and there are also hydraulic systems to lift heavy objects. The operating mechanism is used to move heavy objects longitudinally and horizontally or adjust the working position of the crane. It is generally composed of a motor, a reducer, a brake and wheels. The luffing mechanism is only equipped on the boom type crane. The amplitude decreases when the boom is raised and increases when it is bent down. It is divided into balanced luffing and unbalanced luffing. The slewing mechanism is used to rotate the boom, which is composed of a drive device and a slewing support device. The metal structure is the skeleton of the crane. The main load-bearing parts such as the bridge, boom and gantry can be box-shaped structures or truss structures, or web structures. Some can use steel as supporting beams.

[0004] When existing cranes are lifting heavy cargo, the crane columns may not have enough lateral support, resulting in unbalanced force on the entire crane, reduced braking force on the boom, and even tipping of the crane, which affects the crane's lifting operation. Utility Model Content
