First, the basic principle of folding arm crane

Folding crane is a special lifting equipment, mainly used for lifting heavy objects. Its basic principle is to use the hydraulic system of the boom to control the expansion and lifting of the folding arm, so as to achieve the functions of lifting, lifting and suspension of heavy objects. The boom of the folding arm crane is usually composed of more than two supporting arms, which can be telescoped between the supporting arms, so that it can adapt to different lifting heights and spans.

Second, the advantages of folding arm crane

1. High reliability: The crane adopts high-quality hydraulic system, which can operate normally in various environments and working conditions and has strong reliability.

2. Good stability: the folding arm crane has good balance performance, and the heavy objects are not easy to shake or tilt during the lifting process, which is more stable and reliable.

3. Long service life: Due to the use of high quality materials and advanced manufacturing technology, the crane has a long service life.

4. Wide range of application: folding arm crane is suitable for hoisting on various occasions, not only can be used indoors, but also can be used outdoors, very flexible and convenient.

Three, the shortcomings of the folding arm crane

1. High installation cost: The use of folding arm crane needs to be installed, which will have a higher installation cost compared with other lifting equipment.

2. High maintenance cost: the folding arm crane needs regular maintenance and maintenance during use, and there will be a certain maintenance cost compared with other lifting equipment.

3. The operation is difficult: the folding arm crane requires professional personnel to operate, so the operation is relatively difficult. Knowledge and skills are required to perform the operation.

【 Conclusion 】

In summary, as a lifting equipment, the folding arm crane has the advantages of high reliability, good stability and long service life when hoisting heavy objects, but it needs to consider the shortcomings of high installation cost, high maintenance cost and difficult operation when using. Therefore, when choosing a folding crane as a lifting equipment, it is necessary to weigh it according to actual needs and conditions.
