Manufacturing and Anti-Corrosion Process
Our welding procedures are approved by major classification societies. The surface treatment reaches Sa2.5 blasting standard, followed by an anti-corrosion coating system consisting of zinc-rich epoxy primer, epoxy micaceous iron oxide intermediate coating, and high-build aliphatic polyurethane topcoat, with a total dry film thickness of no less than 250 μm. This coating system provides 5–10 years of corrosion protection.
For selected products, hot-dip galvanizing (HDG) is also available, improving corrosion resistance by up to 300% and offering more comprehensive protection for harsh marine environments.
Customization and Component Brands
The crane design can be customized according to customer requirements.Key components can be selected from internationally renowned brands or high-quality Chinese brands upon request. Available options include, among others, motors from ABB, Hoyel, SEW, and Siemens; hydraulic pumps from Danfoss, Parker, and Rexroth; hydraulic motors from Sai Danfoss and Staffa; and control valves from Danfoss, HAWE, and DYDEN Japan.
