How to maintain the appearance of a gantry crane

How to maintain the appearance of gantry cranes with fake joints given by Shandong gantry crane manufacturers?

The materials used for gantry crane equipment need to be suitable for their working environment. Before selecting materials, gantry crane manufacturers must first understand the detailed usage requirements of the crane equipment, especially for gantry cranes and semi gantry cranes that operate outdoors. In terms of material selection, they must ensure first-class quality, defect free, and long service life.

For some lifting equipment that comes into contact with water, chemicals, etc., the standard requirement is that the surface of the equipment submerged under the substance must ensure strong anti-corrosion ability to prevent equipment corrosion or damage caused by long-term contact with special substances. In this case, stainless steel material can be selected to reduce future maintenance processes. What should be taken seriously here is to prevent electrical corrosion caused by metal foundations with very close potentials. The best way is to use insulation materials such as rubber to isolate the corrosion source.

Painting standard for gantry cranes: The steel surface of the main components of the steel structure shall be shot blasted, and the important components shall meet the Sa2.5 level in GB8923. After shot blasting treatment, paint is applied. The primer is coated with epoxy zinc rich primer, the intermediate paint is coated with two coats of epoxy anti rust primer, and the topcoat is coated with two coats of paint. Requirement: The surface of the topcoat should be uniform, fine, shiny, and consistent in color.
