Tower Crane Characteristics
Compared to other company's construction machinery, our construction machinery has the following features:
1. The using steel is 16M and Q235B which the manufacture is Shanghai Baosteel. After test for qualified, then can use.
2. Painting Process. After shot-blast cleaning, spraying anti-rust paint, then spray paint.
3. Welding process use high-strength wire. Main joints use special steel and special process. Mingwei company is the first company to adopt mast sections and main chord robot automatic welding system in China. The system is reliable in performance and high efficiency with high degree of automation, so that one worker can observe several welding systems. The quality and efficiency of welding are greatly improved. In terms of the welding quality of main load structure, the products reach the advanced international standard.
4. Electric device. Use international well-known manufacturers' electrical products, such as Schneider.
5. Motor, deceleration devices use domestic famous manufacturers' products, eg: Shanghai, Jiangxi Special Electric Motor Co., Ltd.,Tianjin etc, to ensure the long life.
6. For cab, electrical device box, acid cleaning and parkerising, then painting, to ensure a long usage life.
7. Machine total weight is 3-5 tons heavier than the same type of tower crane in other manufacturers.
8. Each device is in strict test, then can packed to ship, to ensure that the trouble after leave the factory reduced to the minimum.
9. Reliable quality, advanced technology, reasonable price, the best configuration, high safety factor, cost-effective ---MINGWEI products is trust worthy, we can ensure the customers buy the products assured and use happy.
