Construction rigs and their modifications
In the metro, many observed a strange high construction, modestly standing at the end, sometimes in the middle of the station. Quite powerful wheels, each of which is equipped with a brake and supplemented with a stop, high racks, obviously sliding, on the top platform. Actually, these are the same building towers, which were used to replace the lighting elements in the chandeliers of subway stations. Similar designs exist both in airports and railway stations, from which it is convenient to wash the glass in the high terminal halls, to wipe the lampshades.
There are few types of such towers, and they are usually divided into demountable and mast undivided structures. The latter may have a scissor mechanism for lifting the site, this is the version that is currently in greatest demand. There are also light models with a block mechanism, the internal section raises with the help of cables a powerful winch. With regard to the dismantled sectional version, in such a modification as scaffolding is used a tour with a rigidly fixed platform or several tiers of platforms.
Construction tour for high-altitude work
If skyscrapers are usually used for hanging skyscrapers, then in low-rise construction it will be enough to use as a scaffold tower tours that can reach heights of up to 22 meters. The higher the design, the easier it should be, so some elements for models that can be tilled with sections up to a couple of tens of meters are made of aluminum( other than poles) .In the same place, where strength is needed, for example, with a high load on the structure due to the use of various small construction equipment, all the parts of the sections are made of high-grade steel.
The highest tower structures are supplied with additional supports up to 2 meters in length, and are attached to the wall when reaching a point of 11 meters.
However, the aspiration to height also causes certain inconveniences. In particular, it is practically impossible to move such a tower, and it is dangerous, one unevenness is enough to make the displacement of the center of gravity critical. That's why for such models make fast detachable fasteners to the wall of the building. There is also such a factor as safety engineering, in particular, when the design becomes higher than 10 meters, it is necessary to install a second flooring, safety. A construction tour of the telescopic sections on the winch should move apart without people and any cargo on the site.
Mobile tower for private needs
Because most of the building scaffolds are used in low-rise buildings, they are very popular with private sector developers. However, not all the owners of suburban areas are ready to hire a team of workers, since it will cost a considerable amount. How to be the one who plans to independently carry out all the construction and decoration work on the outside and inside? You can use goats and a stepladder, but this is extremely inconvenient, so we immediately dismiss this option.
It is much better to purchase a minimum set of several sections, which can be built up to 4 meters. This is enough to build a single-storey house, and in the premises can be used. However, if in the future the mobile tower is, in your opinion, neither you nor your relatives will need it, it is not necessary to buy this structure. In the newspapers you can find a lot of announcements about rent of construction equipment, both short-term and long-term .
Choose the option with the most suitable conditions for you is not difficult. Sometimes the terms of the lease include the delivery of forests to the specified address. Perhaps this service will require a small surcharge, but in the absence of own transport brought directly to the site of the tour is an additional cost.
