The Total Combined Sail Weight of the lighting, camera, artwork or other equipment including its headframe mounted on the pole and the impact of wind on this total area. This can be increased by the sail offset if objects mounted on the pole are not uniformly distributed on the pole or mast such as they are located on one side only.
The Mounting Height of the lighting or other equipment on the column. The height at which a light, camera or other equipment is mounted on the pole will impact the engineering requirements for its manufacture. The higher that an object is mounted on the pole the greater the load will be on the pole or mast.
The Location of its Installation as wind speeds vary throughout Australia the location of a pole in either in a Wind Region A, B, C or D will effect its design. Below is a map of the various wind regions in throughout Australia.
