Description

Technical Field

[0001] The utility model relates to the technical field of hoisting equipment, in particular to an anti-fool device which can prevent a large hook of a crane from rotating. Background Art

[0002] Double-bridge crane is a kind of lifting equipment composed of two independent booms, which is widely used in industries, ships and other fields. This structural design makes the double-bridge crane have higher flexibility and load bearing capacity, and can achieve efficient and stable operation in complex working environments. Each boom of the double-bridge crane is equipped with an independent power system and control mechanism, so that it can be lifted and rotated independently. At the same time, data exchange and communication can be carried out between the two systems, thus ensuring the stability and reliability of the entire system. In addition, since the boom length of the double-bridge crane can be adjusted as needed, it can also play a good role in space-constrained environments. However, the double-bridge crane also has some limitations, such as its large size and heavy weight, so the installation and transportation costs are relatively high. In addition, its control system is also relatively complex, requiring a large amount of technical support and maintenance costs. Therefore, it is necessary to pay attention to reasonable planning and scheduling when using it to avoid unnecessary cost waste.

[0003] The factory design of the crane hook is 360° rotation. When lifting aluminum bars, the crane hook will rotate naturally, which can easily cause the aluminum bars to collide and there is a problem of the aluminum bars tipping over and falling. When used in deep wells, the hook cannot be guided to rise and fall, which will cause the hook to shake when lifting goods, affecting the lifting stability.

[0004] Therefore, it is necessary to provide a new anti-fool device that can prevent the crane hook from rotating to solve the above-mentioned technical problems. Utility Model Content
