Advantages
1. Craftsmanship
(1) Advanced equipments for rust-removing applied in material pretreatment process to ensure rustless structure welding.
(2) Precise data control cutting machine ensures accurate specification of each component.
(3) CO2 shielded arc welding ensures welding quality thereby enhances the longevity of the products.
(4) High-quality surface coating that can meet different requirements of transporting and using. It is durable under environments of low, high, wet as well as oceanic environment.
2. Leading technology of working mechanism
(1) Hoisting mechanism: Matching with frequency tansforming & mulipolar dynamo resistivity for timing. Stably shifting impules the electric fence gently. Multipolar dynamo works stably, it is simple and economic with gentle impulsive currency when starting and shifting.
(2) Trolley mechanism: Frequency transformer and wire wrapping motor can be applied to conduct speed regulating. It is economic and convenient to operate.
(3) Slewing mechanism: Frequency transformer and wire wrapping motor can be applied to conduct speed regulating.
Using of electronic components from world famous brands, that ensures stability and reliability of the products.
