Painting cycle and standards: The metal structure of the tower crane should undergo a complete repainting every 1 to 2 years. Before painting, all rust spots, oil stains, salt crystals, and other adhering substances on the metal surface must be thoroughly removed to ensure a clean and dry base.
Special protection for key areas: For structural components, weld seams, and heat-affected zones that are exposed to the elements for a long time, the thickness of the anti-corrosion coating should be increased. In coastal and highly corrosive environments, additional protective measures such as applying anti-corrosion tape or using high-grade lubricating grease should be taken on the wind-facing surfaces and areas prone to water accumulation of the tower body and lifting arm, etc.

In coastal high-corrosion environments, additional protective measures such as applying anti-corrosion tape or using high-grade lubricating grease should be taken on the windward surfaces of the tower body, the hoisting arm, and areas prone to water accumulation.
Anti-corrosion of fasteners: The connecting bolts and anchor bolts of the tower body, etc., should undergo dual anti-corrosion treatment of galvanization and epoxy resin. The internal part of the bolt sleeve should be filled with waterproof sealing to prevent salt fog from penetrating and causing internal rusting.
