Assembly for chemical anchors - description of the technique
Read more: Assembly for chemical anchors - description of the technique.Most of our wall-mounted masts are installed using chemical anchors and threaded rods. This is a very convenient and durable method, though it is sensitive to installation errors. The forces acting on the bolts—especially for taller and more heavily loaded masts—can reach values measured in metric tons, so the quality of the mounting is crucial. General note: if you are not a professional installer…

Reactions to building structure – what should I know?
Read more: Reactions to the building structure – what should I know?Customers often wonder why the mast mount is more expensive than the mast itself. The values of the pulling and driving forces in the roof quoted in the static calculations show how important proper anchoring is, which often requires serious construction works and specialized solutions, individually tailored to each building.

Anti-fall system – what is it and how does it work?
Read more: Anti-fall system – what is it and how does it work?Working on towers and masts can be dangerous. Manufacturers’ recommendations are clear: work at heights should not be performed when wind speeds exceed 5 m/s. Safety harnesses or mountaineering harnesses are helpful in everyday work—they significantly increase safety, albeit at the expense of comfort. Changing position on a mast is particularly cumbersome: every step requires repositioning the lanyard, which in practice leads even experienced…

I'm putting the mast/tower on the ground - how should I foundation it?
Read more: I'm putting a mast/tower on the ground - how should I foundation it?The general rule is that a foundation should not extend below the groundwater level. If the groundwater table is shallow, the most common solution is a foundation slab weighted down with earth fill or shallowly buried precast elements (so-called “mushrooms” from the F series, e.g., those manufactured by Elbud Gdańsk). Cast-in-place slabs are also used in mountainous areas, where just below the ground surface there are…

How to remove lightning from a mast safely? Basic knowledge.
Read more: How to remove lightning from a mast safely? Basic knowledge.W przypadku odgromienia masztów telekomunikacyjnych należy wziąć pod uwagę trzy główne zagadnienia. Ładunek elektryczny najlepiej i najtaniej – naszym zdaniem – odprowadzić przez samą konstrukcję masztu lub wieży kratownicowej. Produkty AluPro wyposażone są w specjalne ucho w najniższym segmencie, które umożliwia przyłączenie całości do instalacji odgromowej budynku. W przypadku konstrukcji malowanych należy pamiętać o usunięciu…

Mast and tower service – what should I know?
Read more: Mast and tower service – what should I know?Radio masts and towers require regular inspection and maintenance to prevent breakdowns and life-threatening hazards. Aluminum masts are resistant to corrosion, but susceptible to frost cracking. The condition of guy ropes and rope tension should be checked, and regular anti-corrosion inspections of steel structures are necessary.

How to properly arrange mast lashings?
Read more: How to properly arrange the mast lashings?Ogólna zasada mówi, że odciągi należy rozmieszczać symetrycznie – w masztach trójkrawężnikowych co 120° w rzucie poziomym. Jeśli chodzi o odległość punktu kotwiczenia od osi masztu w rzucie poziomym, przyjmuje się, że nie może być ona mniejsza niż połowa wysokości masztu. Przykładowo dla masztu 50-metrowego punkt kotwiący odciągi powinien znajdować się nie bliżej niż 25…
