WHY AREN’T GUYED TUBULAR TOWERS INSTALLED ANYMORE?

Why aren’t guyed tubular towers installed anymore? 

For many years many guyed tubular towers were installed all over the world 🌍. These were very simply manufactured towers, which were assembled on the ground and lifted with a ginpole, with the help of a winch. The guy wires were installed in four perpendicular directions.

✅ Its advantages were its low cost 💶, and its easy installation 🛠️ without the need for staff specialized in work at height and, despite being very light, they provided good performance in wind 💨 or ice ❄️ loads.

❌ The disadvantages include the need for a large surface area of flat ground (to assemble the entire tower) and the need to lower the complete tower every time some intervention was required on the sensors.

⚖️ It seems that pros and cons are balanced, so why aren’t guyed tubular towers being installed anymore?

👉 The answer lies in the increased height of the towers. When the tubular towers were 50 or 60 meters high, they coexisted with the lattice towers. When heights of 80 or 100 meters began to be requested, the advantages disappeared: the cost was no longer so low 💸, and the lifting was more complex 🧰, requiring more specialized installers 🧑🔧.

❌ In addition, the disadvantages worsened, the need for flat space increased, and maintenance interventions were progressively more complicated, and the tower’s response to loads was no longer as good.

A different case is the guyed lattice towers tilted by the same ginpole system 🛠️, it seems that they have all the disadvantages and no advantages, perhaps for this reason it is a very unusual solution in the current market.
