The design of the masts and concrete foundations and the assembly and erection of the masts including all electrical equipment in the masts.
The installation comprised of five internal access Monopole type masts with the tallest mast having a height of 67 metres and housing 130 floodlights.
The masts were fabricated as 12 sided continuously tapered structures fitted with internal ladders, working platforms and crossarm assemblies for the mounting of floodlights.
The masts, after being transported in sections for a distance of some 1600 kilometres from our factory to the site, were assembled on the ground without any welding being done on site and finally erected making use of 350 ton and 80 ton mobile hydraulic cranes in a tandem lift.
The masts were completed equipped with the lights and all electrical equipment before being lifted into position.
The logistics involved in the installation were complex with the working space around the masts being very limited and the fact that no large cranes were available in the port city meant that the 350 Ton crane had to sent by ship from to the port and then by road to the site.
The masts were designed for the extreme wind conditions of the city of Cape Town and remain structurally sound after many years of use.
