Maintenance of gantry crane appearance by rail shiploader manufacturer

Maintenance of gantry crane equipment appearance by rail shiploader manufacturers: the materials used for lifting equipment must be more suitable for their working environment. Before selecting materials, manufacturers should first understand the detailed use requirements of the equipment, especially for outdoor gantry crane and semi gantry crane. They should ensure first-class quality in material selection, and have no defects and long service life It's a long life.

For some lifting equipment that must be in contact with water, chemical substances, etc., the requirements of the standard are: the surface of the equipment immersed in the material should have strong anti-corrosion ability to prevent corrosion or damage of the equipment caused by long-term contact with special substances. In this case, stainless steel can be selected to reduce the maintenance process in the future. Here, we should pay attention to the prevention of electric corrosion caused by metal foundation with very close potential. The better way is to use rubber and other insulating materials to isolate the corrosion source.

How to maintain the appearance of gantry crane?
