Lighting Structures is the leading supplier of masts for High Mast Lighting in South Africa and other African countries and has been in operation since 1976.
The masts supplied by Lighting Structures are manufactured in our East Rand factory. The production facility is ISO 9001:2008 certified by Dekra.
Railow masts are available in heights ranging from 20 metres to 40 metres. The floodlight mounting ring on these masts is attached to a proven and effective raising and lowering system which allows for easy and cost effective maintenance. Railow masts are ideal for all general area lighting applications with the floodlight mounting ring being able to house numerous combinations of floodlight luminaires.
The floodlight mounting ring, suspended from stainless steel wire cables, is raised and lowered by means of a portable double drum winch which is in turn operated with an electric power tool. The masts are equipped with a complete electrical system including a distribution board mounted in the base of the mast and purpose designed trailing cable for providing power to the floodlight luminaires.
Typical applications are lighting of high density housing areas, industrial yards, roadway interchanges and any application where large areas need to be illuminated from a minimum number of positions.
Midhinge masts are available in heights ranging from 10 metres to 25 metres. The hinging action allows for the floodlights to be lowered to the ground without the use of expensive maintenance equipment. Midhinge masts are ideal for general area lighting applications with the floodlight mounting assembly able to house different combinations of floodlights to suit the application.
The floodlights are brought down to ground level by simply hinging the mast open using a lightweight
portable hand winch. The hinging action is safe and simple to operate by persons with minimum training
and is carried out in a matter of minutes. The mast electrical equipment is safely hidden inside the
mast and only accessible once the mast is opened. The cable supplying power to the floodlight luminaires
need not be unplugged during the maintenance procedure thus allowing testing of the floodlights with the
mast in the hinged down position.
Typical applications are parking areas, roadway lighting and general area lighting.
Internal & External Access Masts
Access masts are available in heights ranging from 10 metres to 70 metres. A caged safety ladder provides access to the floodlights on these masts. The floodlights are mounted on purpose designed cross arms and/or platforms attached to the mast structure and, depending on the application, masts can be designed which are able to house in excess of 150 floodlight luminaires.
The electrical equipment is housed either on the mast or in cubicles adjacent to the mast.
These masts are ideal for sports lighting applications ranging from small training type facilities to major sports stadia such as large cricket stadiums and football fields illuminated for television broadcast lighting.
Internal access masts (named because the access ladder is inside the mast) are used for applications where large quantities of floodlights are mounted on the mast headframe. Generally the electrical equipment, including the floodlight control gear, is accommodated in the base of the mast providing a waterproof and vandal resistant enclosure.
The external access masts have the access ladder mounted on the outside of the mast shaft and are generally used for applications requiring smaller quantities of floodlights where the structure size can be limited.
Access masts are also available for other general area lighting applications such as electrical sub stations, coal stacking areas and similar industrial applications.
Hydro masts are available in heights ranging from 20 metres to 40 metres. They use a portable hydraulic system to hinge the entire mast to ground level for easy maintenance of the luminaires.
Hydro masts are ideally suited to remote locations where the availability of mobile cranes, used for mast erection, is limited and thus costly. The mast is self-erecting requiring only a light duty truck mounted crane to mount the base section onto the foundation. The fact that the entire mast shaft is lowered to a horizontal position allows for inspection of the complete mast at any time without the mast having to be taken down.
The limited number of moving parts ensures a long and virtually maintenance free life of the structure. The mast electrical equipment is safely hidden behind a vandal resistant door and the cable supplying power to the floodlight need not be unplugged during the maintenance procedure allowing testing of the floodlights with the mast in the lowered position.
Hydro masts are ideal for general area lighting applications with the floodlight mounting assembly able to house different combinations of floodlights to suit the application. Typical applications are lighting of high density housing areas, industrial yards and any application where large areas need to be illuminated from a minimum number of positions.
