mast construction
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. This can be seen from the manufacturers' recommendations, which suggest that no work should be carried out on structures when winds exceed 5 m/s. Fortunately, we have occupational health and safety or mountaineering harnesses at our disposal, which significantly increase safety, although rarely comfort. Changing position on the mast is particularly uncomfortable when each step means having to re-attach the reins...
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?Basically, the rule says that the foundation should not extend below the groundwater level. If the water is shallow or very shallow, then a foundation slab loaded with earth embankment is most often used (or shallowly buried "mushrooms", i.e. prefabricated foundations of the F series, e.g. produced by Elbud Gdańsk). Cast slabs are also often used just below the ground surface in areas…
How to remove lightning from a mast safely? Basic knowledge.
Read more: How to remove lightning from a mast safely? Basic knowledge.There are three main issues to consider when dealing with lightning protection from telecommunications masts. In our opinion, the best and cheapest way to dissipate the electric charge is to use a mast or truss tower structure. Alupro solutions are equipped with a special eye in the lowest segment that allows the entire unit to be connected to the building's lightning protection system. In the case of painted structures, remember to remove the coating…
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.
Does a radio mast require a building permit?
Read more: Does a radio mast require a building permit?Masts below 3 meters do not require a permit. Masts over 3 meters on buildings are subject to notification unless local regulations require a building permit.
How to properly arrange mast lashings?
Read more: How to properly arrange the mast lashings?The general rule is that it is optimal to place the lashings symmetrically - for three-curb masts, every 120 degrees when viewed in horizontal projection. As for the distance of the lashing from the mast truss in the vertical projection, it is generally accepted that the distance from the anchor point cannot be less than half the height of the mast. For example, for a 50-meter mast, the anchor brand…
