Self supporting towers are of different types, such as three legged angular towers, three legged tubular towers, four legged angular towers and four legged tubular towers. There is a slight difference in the tower design of a three legged and four legged tower.
Self supporting towers are ideal for cellular sites in urban, as well as rural areas. These towers are free standing structures, which means they do not need additional support like guyed towers. This characteristic of self supporting towers makes them ideal for building a telecommunication network in rural areas as they can be also erected in remote places without any difficulty.
The modern design of a self supporting tower is the result of several refinements that were incorporated after studying the effect of seismic vibrations and winds on the structure and framework of the tower. Telecom towers need to be strong as they have to stand firm on the ground and keep functioning while facing different natural forces such as wind, rain and snow. Self supporting towers have a strong framework and can face natural forces while also protecting the expensive telecom equipment fitted on them. Let’s take a look at the design and some uses of the three legged self supporting tower.
Three legged self supporting tower- Angular design
Three legged self support towers have a triangular base pattern design which incorporates triangular angular elements. The three legged tower is also known as a Type E tower. The design of the Type E tower is specifically optimized for medium and heavy loads. The Type E tower is ideal for standard cellular sites.
The Type E communication tower is specifically designed for heights in the range of 20m to 70m. The tower is supplied in sections which are assembled at the cellular site. The sections of a Type E tower can be easily transported in a standard 20’ ISO container. The tower has a modular design so that engineers can interchange the modules of the tower to make it more suitable for a particular cellular site design.
The tower is made of steel, which is further exposed to anti-rust treatment. The construction of a Type E tower follows a simple principle which is: as the height of the tower or load increases, the material in the lower section of the tower is also increased to make the tower more strong and stable.
A type E tower can be fitted with different telecom accessories that include safety devices, lightning protection kits, antenna mounts, platforms and many more accessories. All these telecom accessories and equipment can be installed at any height and at any orientation as per the client’s requirements.
Recommended uses of three legged self supporting tower:
There are several uses of three legged supporting towers. Some of the uses are:
- GSM/CDMA Equipment
- Wind Turbines
- Radars
- Video Surveillance Equipment
Constructing a self supporting tower is one of the biggest and dangerous aspects of building a telecommunication network. Thus, telecom companies prefer outsourcing this work to telecom turnkey solutions providers that have the expertise and experience required to execute such tasks. The telecom turnkey solution provider also manufactures self supporting towers and other towers required to build a telecommunication network, which helps telecom companies save costs.
