Lighting towers (lighting masts – lighting bases) are designed for display and illumination and for creating lighting at night. These structures are used for lighting and illumination of open environments such as parks, squares, streets, airports, etc. With a simple classification, these towers are divided into several types in terms of appearance.
– Fixed basket light tower
– Mobile basket light tower
– Mobile light tower
These types of equipment are designed for lighting and impact in urban spaces and open environments and are usually made of light metals and have different parts including a base, upper part, projector, lamp and body, etc. To design the lighting towers, the following must be taken into consideration: base thickness, size of the lower opening and the size of the upper opening, and the total opening of the light tower, determining the type of light tower head, determining the number of bolt holes, determining the total number of parts of the lighting tower, and of course determining The thickness of other small and large parts that is explained on the page “Lighting towers structure”.
Lighting bases are equipped with powerful projectors that are made to provide lighting in large environments and are usually made in polygonal form with a high height for lighting large environments. The mobile lighting tower has level control arms and a lock on the top of the tower to guide, stabilize, keep level, and prevent the rotation, rotation, and movement of the basket they act as light distribution, and by using powerful projectors, the light is directed to Widespread in the environment. These products are made with different heights from 6 to 70 meters depending on the type of application and the place of use and are used in wide environments to provide lighting for large areas such as parks, promenades, squares, streets, bridges, airports, and sports stadiums. Hospitals and factories are used. These towers have high efficiency due to their high flexibility, easy maintenance, and repair, resistance to cold, heat, wind, and rain, distributing light without creating shadows and illuminating the environment in a very extraordinary way.
Telescopic light tower and stadium
Based on the type of light, we can divide the light tower into two new sub-branches: telescopic and stadium type.
The telescopic sample has a round and circular head and is suitable for 360-degree lighting, and the telescopic tower can be fixed in two types, which are used in parks, airports, squares, urban centers, etc.
There is another type of lighting tower that has an obvious difference in application. This difference is the ability to emit light in a concentrated manner, and stadiums are the epicenter of this lighting power. It can also be installed and used in stadiums, factories, docks, etc. Can you imagine watching attractive football matches at night without the stadium light tower and in total darkness? This powerful product has helped a lot to organize sports competitions at night and is extremely popular.
The user needs to determine what type of product to choose. For example working time and completion of the installation site project, for example, a construction workshop or a movie project is a temporary need, and the mobile model is the right choice.
- Fixed basket (head) (in two samples “without a ladder and with a ladder).
- Movable basket (head) (in two models: manual with winch and handle – gearbox electric motor).
- Mobile with the ability to move the installation site to different areas
These towers are usually made of light metals and have strong lights that are connected directly to the city’s electricity. They are designed in four and eight-sided ways. Lighting towers are installed overlapping. For the construction and installation of lighting towers, some things must be checked carefully before production. Wind speed, ground structure, and soil type at the installation site, tower weight, base diameter, and tower height, light tower mast strength are considered. To install the structure of the light tower (lighting tower) in an overlapping manner, the tower is produced in 6-meter pieces and they are installed at the installation site by compressive force.
Repair of lighting towers includes installation of projectors, repair, and replacement of electrical panels, repair and replacement of electric motor and gearbox, replacement of lamps and projectors, and cleaning and cleaning of projectors, which must be done in specific periods.
Requirements for the design of lighting towers
To design these products, all the technical specifications of the tower should be considered and according to the type of structure and application of the tower, a suitable design should be chosen for the work. Some of the technical specifications of the lighting tower include the following
- Dimensions and height
- Determining the thickness of the work base
- Determining the number of bent sides of the pieces
- Determining the size of the bottom and top openings of the parts and the whole tower
- Determine the type of head
- The number of bolt holes
- Determine the total number of parts
- Checking the thickness of each piece
Lighting tower, factors affecting the price of a light tower
- tower height
- Foundation type
- Bottom-to-top opening size
- The type and quality of galvanized coating according to the weather conditions of the installation site
- Sheet thickness and quality
- The diameter of the tow wire
- The number and dimensions of Lakhi
- The number, type, and quality of projectors and the amount of light emission
and other pieces.
Lighting towers are produced in two useful and non-useful ways, and the difference between the two methods can probably cause a possible difference in the calculation of the height of the light tower:
Useful method: the pieces of the light tower are placed on top of each other in the form of overlapping and overlapping, as a result, each piece enters another piece, so the height should be considered more to get the original height after the work is finished.
Non-useful method: if the structure is produced in a non-useful way, the height of the overlaps is not considered and only the final height is considered, for example, for a 24-meter light tower, 4 pieces of 6 meters are considered, but at the end of the work, the height Tower will be 5/22.
