Self supporting tower is a type of telecom tower. So, they are often used in the telecommunications and broadcasting industries. It is worth noting that, supports its own weight, and therefore does not need cross bracing against other structures. Their design is such that, unlike other towers, most of the tower's height must be built wider, as the narrower base cannot support its weight.
This section will explore and elaborate on the different types of self-supporting towers available in the market.
Straight leg self supporting tower
Straight leg self supporting towers are the most straightforward design of the self-supporting tower. Many consider them to be the 'basic' design. The legs are straight and designed in a way that allows for a strong and stable structure. The base is much wider than the top as this design supports the weight of the tower very well. One clear benefit of this design is that it provides a good amount of space at the top for antennas or other equipment.
Diagonal leg self-supporting tower
Many people consider diagonal leg self-supporting towers to provide more support than the straight-leg models. This design uses diagonal bracing with only leg 'cross' members for strength. The cross member provided allows for forces to be transferred throughout the structure in a more even manner. This helps to eliminate some of the stress that may build up in particular areas of the tower. Thus, users can find this type useful for heavy loads or tall towers as the diagonal bracing helps prevent bending or swaying of the tower.
Flat panel self-supporting tower
A unique feature of the flat panel self-supporting design is how the legs are constructed. Instead of the rounded shapes of the earlier designs, these panels have a very slim profile and look almost two-dimensional. This type of tower is advantageous for wind resistance as their form is very streamlined. Although this type might not appear as sturdy as the earlier models with thicker beams, their mathematically designed shape still offers lots of strength for use in windy areas.
Triangular self-supporting tower
The triangular self-supporting tower is a classic tower design. This design has 3 angled sides instead of straight up and down legs like the other types. The triangular shape is very strong and holds it's own even when very thin. This makes it good for areas that are prone to strong winds or storms. Though it doesn't have as much room at the top for antennas as some of the other designs, its powerful form means it doesn't sway around much when windy.
Cubic self-supporting tower
This tower design looks like a cube from 3D tower with shortboxy legs supporting the top. BIG and blocky these types are very strong but can catch a lot of wind too. They are best in areas where towers tend to bend over frequently due to gales as their sturdy build won't warp easily. Though not very aerodynamic shaped, reinforcing inside helps reduce strain on whole framework when storms roll through.
The self supporting cell tower has multiple industrial applications. Some of these applications include the following:
Telecommunications and broadcasting
Telecom towers provide important coverage for cell phone signals, Internet access, and TV/radio broadcasts. Their unique shape lets them stand tall and strong even when winds try to blow them over. This keeps the signals clear and reliable, no matter how stormy it gets outside. Without the self-supporting design, many of the signals would become weak or simply get lost. So really, these towers help keep all those communications connected.
Vhf and uhf TV transmission
They have height and strength to send those signals far and clear to homes in every direction. Their special design means they won't bend or break, even when strong winds blow. This ensures TV shows and games always come through crystal clear without static or interruptions. They provide antennas and keep them high up to give viewers the best reception.
Emergency services and government operations
Self-supporting towers are large structures that can withstand the forces of nature whilst providing significant height to ensure coverage. They provide a strong and reliable means of communication between emergency services so that they can coordinate their activities effectively even in the most remote locations.
Construction and geographical mapping
Self-supporting towers provide capability and elevation that ensure they are able to scan great expanses of land. When placed atop construction sites or mobile platforms, these towers give surveyors and builders the vantage point required to plan complex projects safely.
Wind and weather monitoring
These towers rise above storms safely so scientists can understand winds and gales without danger. Invaluable for forecasts, fishing, and flying, they help predict and protect from nature's fury with precision.
Energy harnessing
Specially designed self-supporting tower types rise hundreds of feet above storms and powerful winds without bending. This provides a safe platform for engineers to attach blades high in the gales and generate electricity from nature's breath.
This section will focus on the product specifications and features of self-supporting towers.
Three-legged design
The three-legged design lifts the tower above the ground. This allows much more space to attach antennas or other gear at the top compared to a typical rooftop.
Modular construction allows for easy assembly
Prefabricated sections bolt together quickly on-site, raising the telecom structure in short order.
Durable and weather resistant
Thick galvanized steel and rustproof coatings let it withstand storms, heat, ice, and corrosion for decades without weakening from wear.
Versatile applications
They are utilized by cell networks, radio, and TV stations to transmit signals across urban and rural areas, plugging coverage gaps.
Innovative self-supporting structure doesn't need extra braces
This unique frame lets it remain steady even during violent gales while completely freeing up room along the tower's vertical length.
The choice of self-supporting depends largely on the structural design considerations that come with each unique self-supporting design. Therefore, in this section, various factors that need to be put into consideration when choosing self-supporting towers will be discussed.
Height requirements
Increasing the height of a supporting cell tower increases its coverage area and makes the signal drop less intense. However, self-supporting towers are designed to be strong and rigid, and they can withstand the forces of nature, such as wind. Therefore, while considering the coverage area, coverage area should not compromise structural integrity.
Load bearing capacity
Different self-supporting cell towers come in different load-bearing capacities. While some can carry a heavy load, some cannot. Although many of the self-supporting cell towers are fabricated from steel lattice, which provide strong support and at the same time light weight. They can carry heavy objects on the top part of the tower, such as more antennas, but they also need to be helped to hold up greater weights. Choose a tower that will support both the weight of the tower and the equipment that will be mounted on the tower.
Wind and weather resistance
Wind loads are some of the most critical factors for self-supporting tower designs, especially in areas prone to storms. Check how the chosen tower design fares against large gusts and whether bracing or other features enhance its stability in vicious gales.
Building codes and regulations
To maintain safety and welfare, self-supporting cell tower designs are regulated. Many of these regulations came as a result of observing many tower collapses and the need to ensure everyone's safety. It is, therefore, important to build according to local ordinances. That information, along with the info on the telecommunication tower, can typically be found on one website.
Material composition
Various materials are used to make self-supporting towers. These include steel, aluminum, and hybrid materials. All these come with pros and cons. Steel towers are heavyand do not permit much wind through, offering an extremely solid but lightweight structure. Aluminium's lightness allows easy handling, but it won't support as much weight. Hybrid blends balance the two strengths together. So think about which material makes the most durable, efficient tower for the weather conditions to face.
Of course, it's possible to ground the antennas on a self-supporting tower. In fact, many designs incorporate grounding as a protection measure against electrical surges. By securely anchoring antennas to the tower base, it helps dissipate lightning safely into the ground. This reduces potential damage from storms while providing a sturdy platform that stands tall without needing extra support.
Most self-supporting towers are made of steel. Steel has a high strength-to-weight ratio. Apart from that, they are also corrosion-resistant, allowing them to be used for a self-supporting tower in various applications. They can also be manufactured from aluminum for lighter but not as strong options.
The independent design of self-supporting towers helps elevate what needs held above the ground - antennas and equipment. Unlike guyed towers that slant support cables everywhere, these stand solidly on 3 or 4 legs. This makes them smaller, easier to fit in tight spaces, and simpler to install. With no extra bracing, they also provide an open area at the top for antennas to send signals out far and wide.
Yes, they can. All the open latticework and cross pieces let fierce gusts blow right through without toppling over. So they stay steady and solid, even when the storm winds whip around the tower faster than a race car. Thanks to how they're built, strong tower designs keep standing proud and shining with signals, rain or shine.
Although all lattice towers are self-supporting, not all self-supporting towers are lattice towers. Lattice towers are designs with triangular or square latticework legs crisscrossed with bracing. Many other styles exist too, like monopoles or woven towers with unique twig-like shapes.
