Coastal container yards are one of the harshest environments that lamps can face. The combination of salty air, continuous vibration of loading and unloading equipment, coupled with high wind loads, will greatly shorten the life of any lamp selected according to inland warehouse standards.

Anti-corrosion is the first specification. ISO 12944 classifies atmospheric corrosivity. Coastal and offshore environments belong to Class C5, where C5-M represents marine conditions. This means a documented coating system-usually multiple layers of epoxy and polyurethane on properly pre-treated substrates-is needed-rather than ordinary powder spraying. In this environment, aluminum shells with stainless steel fasteners perform far better than painted carbon steel.

The second item is wind load. The high-pole lamp is designed according to the wind pressure in the area where it is located, but the lamps installed on it will increase the wind-receiving area. A lamp that is large and square in shape will raise the load of the entire pole; and a lamp that passes the wind pressure assessment does not automatically mean that it passes the vibration assessment that it will withstand. If the installation point is within the working range of a front crane or quayside crane, please inquire about the anti-vibration test.

Next, maintenance is planned. Ports are usually operated continuously, and maintenance costs are very high once cranes or closed operating areas are needed. Using fewer and higher light poles to achieve wide and uniform light distribution can reduce the total number of maintenance points; and remote monitoring of the drive allows you to proactively repair it when a failure occurs, rather than waiting for a complaint to discover it.
