•Production and assembly may be performed by Hungarian subcontractors and costs of those works are to be kept at a low level.
The 30m high ECOPOL prototype is made of a laminated-glued timber structure combined with an internal steel frame connecting the wooden elements. The inner structure has a triangle shaped layout confined by laminated wooden plates. From the vertices of the triangle rise three laminated timber supporting beams. The beams are narrowing upward along a parabolic arch, thereby resembling the exponential growth function of natural trees. Connection between the tower and the base block is ensured by cemented anchoring steel frame.
The fall arrest safety ladder is placed on one of the sides of the inner prism, which enables access to the antenna platforms and also the top of the tower. Inlet hatches and caple hatches are placed on the other two sides of the prism.
Steel elements are protected by zinc coating against corrosion and the wooden elements are treated with a special protective finish.
Prototypes are equipped with an intelligent measurement system which continuously monitors the status of the tower in the context of wind speed/direction and strain/deformation. We also conduct wind tunnel experiments on different model versions with the support of the University of polytechnic to continuously improve the characteristics of our product.

During development one of our main requirements was to use timber as building material and also the shaping the geometry to be aesthetic and being in harmony with nature. Therefor we favoured smooth curves as opposed to straight lines and angular solutions. The final geometry was made to resemble the giant trees of tropical rainforests: the shape of “wings” of the tower are analogous to the buttress shaped tree-roots.
We have aimed to meet the requirements below:
•Towers are aesthetic, max. 40 m height, self-supporting, made of timber and laminated timber.
•Capable of hosting the antennas of up to three mobile operators on different levels at the top section of the tower; cables run down to radio equipment hidden in the inside of the tower.
•Sufficiently rigid to comply with deformation of telecommunications antenna and equipment.
•Provides proper space to perform necessary maintenance and operation works on the antennas and also easy access in line with effective security requirements.
•Compliance with effective Hungarian static standards and specifications.
•Proper coating ensures long term protection to the timber structure being exposed to extreme weather conditions.
