How to use a three-section ladder. Instructions for use of stairs

For those people who often work at height, stairs have long been invented. They may be various types and dimensions, but the most versatile is considered to be a three-section aluminum ladder 3x10, combining all positive characteristics other types of stairs.

Such stairs have the ability to transform, depending on the work performed.

general characteristics

Aluminum three-section ladders, as their name implies, consist of three sections, each of which, individually, is also a ladder. Two of these sections are connected to each other. The connection can take place different ways, but most often these are durable belts.

The third segment is retractable; in terms of its characteristics, it does not differ in any way from the previous two stairs, but unlike them, it can be detached from the main structure. The detachable segment can be used as a ladder after being detached.

A ladder can also be built using all three sections. All you need to do is fold the two fastened segments and slide out the third. The result is a very long retractable ladder. As a result, buying one staircase, the buyer receives several stairs at once:

three-section;
two-section ladder;
attached short;
attached long;

Thanks to the ability to move forward and rebuild, such a ladder can be used for both indoor and outdoor work.

Universal ladders have a different number of steps, usually no less than 6 and no more than 16. A ladder with 10 steps will allow you to work at a wide range of heights, from 3 to 7.5 meters.

However, do not confuse the maximum length of the ladder and its working height. The maximum length is the length that the ladder can extend to the maximum. And the working height is the sum of the length of the ladder and the height of a person, at which it will be convenient to work.

For safe work at height, the stairs are equipped with interlocks. Usually they are made in the form of hooks, which can be unfastened and fastened only by hand. This is done in order to prevent spontaneous unfastening or slipping of the lock when the ladder is extended.

Advantages of three-section ladders

Three-section aluminum ladders have a lot of advantages over their one- and two-section counterparts. The presence of these advantages, they are largely due to the uniqueness of their design and the quality of the material used in their manufacture.

The main advantages of aluminum three-section ladders 3x10:

the ability to get several types of stairs from one;
suitable for indoor and outdoor work;
good structural strength;
not afraid of moisture;
light weight;
compactness in storage and transportation;

durability of use;
structural stability;
the ability to adjust the height;
ease of use and maintenance.

Since the height of work on such ladders is high enough to cause injury, increased attention is paid to the safety of operation. The stairs are equipped with anti-slip pads, their steps have a ribbed surface, and of course the blockers necessary for fixing the extended part.

Note! Unfortunately, the retractable ladder does not have wide steps, and long work on high altitude become doubly dangerous. However, you can now purchase an additional platform in stores.

Such a platform serves as a replacement for narrow crossbars. It is attached to the stepladder, and makes it possible to carry out long work with great convenience.

Convenience and functionality of a step-ladder is necessary both during repair and installation work, and in everyday life. Sellers of any self-respecting large store use stepladders to somehow get to the top shelves with products. And when carrying out repair work only ladders will help you reach the desired goal.

Unlike scaffolding, tower tours have a number of advantages: a small construction area, quick installation and ease of transportation in disassembled form. The wide range of applications makes it very popular. With success, it is used for installation in any premises with limited space, if it requires work at high heights and higher stability than a ladder or stepladder. Exist towers for working inside tanks , they have small size parts (up to 450 cm) disassembled. Thanks to this design feature parts can be easily lowered through a small opening (cistern neck or technical manhole) and the tower can be assembled inside the tank. Our catalog also contains models that can be used both for working on a flat surface and for work on stairs .

If you have one-time work that does not require the constant use of this tool, then in our store you can rent a tower required height (look in the catalog for products marked for rent).

If you decide to make a purchase, then when choosing, first of all, you need to decide on the purpose of use. There are aluminum or steel models. Steel, due to the strength of the material used, allow a greater working height compared to aluminum, but aluminum have a much lower weight, which is important for frequent transportation. The exception is aluminum towers. professional series. Our product catalog contains a model of the series RAPIDO 250 manufactured by FARAONE (France)- with a height of the working platform up to 16 meters with maximum load 300 kg. Below is a list specifications which should be taken into account when purchasing and further operation.

Material aluminum or steel
Platform Height
Overall Height
Platform length
Platform Width
Equipment with stabilizers

Pay attention to the technical specifications: platform height, load capacity, platform dimensions and the total weight of the entire working structure.

It is difficult to overestimate this tool, as it has a wide range of applications in everyday life and at work.

If you have Vacation home, garden, or just construction is going on, then ladder ladders are simply indispensable, reliable helpers needed when construction work, in the country, at home, as well as for collecting ripe fruit from tall trees.

If you decide to make a purchase, then when choosing, first of all, you need to decide on the purpose of use. How to do it anyway right choice.

First of all, it is necessary to take into account several such important factors, as a class or scope of the product (household or professional), material, maximum permissible load, the width of the step, the presence of additional options - a special tray for tools and a hook on which you can hook a bucket. Many buyers initially do not pay attention to this. Although all these parameters are indicated in the product passport or on the packaging. So let's try to understand this issue in detail.

Below is a list of technical characteristics that should be considered when purchasing and further operation.

Material aluminum or steel
Distance to job site
General dimensions
Roll bar size
Working platform size
Step width

The optimal height is determined quite simply, for this you need to measure the distance to working area, to which you will need to get, and from it already take away your height and about 30 cm more, so that, when working, do not rest your head on the ceiling. All models have the distance to the working platform, so you need to make calculations from it.

If, for example, a staircase is chosen for an apartment, then four or five-step models are usually suitable, their working platform is about 70-100 cm. A household platform is often suitable for use in production, which can change its height characteristics depending on the wishes and needs . You can also consider the option of tower tours, but this is already for more global tasks, such as facade work, masonry or decoration.

From the material you can choose aluminum ladders, steel or steel with aluminum steps. Here the frequency of use and the need for its movement play an important role, since the weight also differs depending on the material. For example, aluminum stairs are lighter than the steel model, so it is easy to move if necessary. Aluminum ladders are good for home use, with capital or cosmetic repairs Steel is heavier, so they are often used on various industries. But here we should not forget about professional ladders, all professional models are made of high-strength aluminum alloy, the profile itself can have additional stiffeners, which allows it to withstand loads up to 250 kg. Such ladders are used when working with heavy loads, for example, you decide to hang a heavy chandelier. You must take into account your own weight plus the weight of the object you are working with.
