How to determine the required height of an aerial platform depending on the floor of the building | Uncle Styopa

One of the most important characteristics of an aerial platform is the maximum reach of the boom, which many people mistakenly mistake for the maximum working height. But this is a mistake - these two values ​​would coincide only if the arrow extended vertically upward. In practice, this is impossible to implement - the chassis of special equipment cannot be placed close to the wall of the building, since in this case there will be no place to place outriggers - retractable supports that prevent the aerial platform from tipping over.

Therefore, when calculating the length of the boom of an aerial platform, it is necessary to take into account not only the height of the work, but also the distance of the possible installation location of the chassis from the wall. The calculation itself is made according to the Pythagorean theorem, since the building itself and the distance from the platform to it are the legs of a right triangle, and the boom of special equipment is the hypotenuse.

Approximate correspondence between meters and floors of a multi-story building.

At the same time, you should not be guided only by this formula - you always need to make a small margin for the arrow reach. Those. if you want to carry out work on the 3rd floor level of a standard brick or panel residential building (where the average height of each floor is 3 meters and there is a 1 meter base), you must order special equipment with at least a 12-meter boom. Knowing this, you can determine what the minimum height of the aerial platform should be when carrying out work on a certain floor of the building.

It is also worth noting once again that these values ​​are minimal and are relevant only for cases when the aerial platform can drive close to the wall. Often, next to the building there is a lawn enclosed by a fence, entrance areas or other structures, which also must be taken into account, since if the chassis can only be placed at a distance of 6 meters from the building, then to carry out work at the 4th floor level, special equipment with a 15-meter boom will be needed clearly not enough.

Work at height is not always carried out in one place - for example, the installation of canopies assumes that a long structure will be fixed at several points located at a distance from each other. This distance must also be taken into account, leaving additional margin for the arrow.

All these calculations are relevant only for typical multi-storey residential buildings. In many buildings located in the center of Moscow, the floors have non-standard heights. For example, on the ground floor there is a store with ceilings of 5 meters, and on the floors above there are apartments with a height of 3.5 meters. The situation is similar in houses with built-on attic floors, industrial buildings and shopping centers. In such cases, the calculation of the length of the aerial platform is carried out on an individual basis, taking into account the required headroom. However, knowing the height of the work and the distance from the chassis installation site to the building wall, you can independently calculate the minimum required boom length using the table.

About prices and rentals

The cost of a tower in the Russian Federation is from 4,500,000.00 rubles, so not everyone can purchase new equipment. On the used car market, the cost ranges from 3,567,000.00 to 4,321,000.00 rubles. Therefore, the best option for short-term work is temporary use. Renting a 28-meter aerial platform per hour of work can range from 900 to 1200 rubles. it all depends on the season and the condition of the equipment, as well as the demand for this service.

An articulated view of the aerial platform.

A very famous type of aerial platform that everyone saw in childhood.
They are very affordable and are much cheaper to rent than their counterparts. The main advantages of these mechanisms include their low cost and ease of maintenance. With such machines, the tower boom shoots at 17-20 meters. This type of aerial platform is most often used during construction work, due to the functions of the boom. It has very high maneuverability and maneuverability. It is indispensable if:

• It is necessary to raise the craftsman to a certain height for façade or construction work;
• Cut trees along the road or wires;
• Lower the worker into the dug trench;
• It is necessary to carry out construction work under the bridge (for this they use a three-armed tower).

It is easy to operate such a machine, but there is a drawback, which is the installation of counterweights for operation. Pulling a person under a bridge or lowering him into a trench is not easy, and something needs to hold the machine, otherwise it will simply collapse along with the workers. Powerful counterweights help, but they take up a very large space, so in narrow places it is already problematic to use.

Vertical aerial platforms

This is the most primitive and least used type of aerial platform. Their lifting mechanism unfolds so that it can only lift the load vertically. It will not be possible to perform any other maneuvers with such a design. For this reason, the scope of application of these aerial platforms is extremely narrow. But in a number of areas, for example, in warehouses or when repairing power lines, vertical lifts can completely cope with the task. The only noticeable advantage of this lifting device is its large lifting capacity.
