In construction and household affairs, it is often necessary to carry out work at height. To ensure maximum safety and comfort, it is necessary to choose and buy aluminum ladderappropriate for your tasks. Let's find out what they are, what they are intended for and in what cases they will be most useful.
Kinds
There are 8 main types of stairs. We will analyze each of them and tell you the best scenario for its use.
Single section
The simplest and cheapest ladder. It consists of two guides and steps (crossbars). The elements are connected to each other, as a rule, by rolling - a reliable and durable method.
You can use such a ladder only in an attached form, leaning on a horizontal or vertical surface. Ease of use and lightness are the main advantages of a single-section ladder. Cons: it is not convenient to transport long stairs; if they are long, they can spring and bend.
two-section
As the name implies, this ladder has two sections and can be assembled into two structures: a ladder and a side ladder.
The parts of the ladder are connected "overlapped" with hooks, forming a strong long structure that can be supported on a wall, roof or tree. If there is nothing to lean on, then the ladder can be assembled in the form of a stepladder. Thus, you get 2 products in one.
Three-section
This is a symbiosis of one-section and two-section design.
The model “can” assemble simply into a long ladder and into a stepladder with variable height, moreover, how simply with an increase in the height of the work being carried out, and with the ability to rely on ledges or recesses. It is quite convenient to transport and gives more freedom to use.
Transformer
It is a non-separable staircase of four spans connected by locking hinges.
This design gives great freedom in the use of the product. It can take the form of a straight or “broken” ladder, a ladder with supports of the same or different lengths, a table or a workbench. This is a truly versatile ladder, ideal for installers. It folds up to four times, which is very convenient for transportation.
Two- and three-section ladder with rope pull
Everyone has probably seen the fire engines and their "magic" ladders, which themselves extend and assemble.
A ladder with a rope pull is almost the same thing. You have at your disposal a two or three-section design, which can be extended if you pull the cable. The spans are connected with hooks, which eliminates spontaneous folding. The model is ideal in cases where you need to change the height frequently, for example, when performing work on the facade of a house.
telescopic
It's a ladder that can fold up like an antenna on a radio.
There are exactly as many sections in such a design as there are steps. The guides have different diameters, from above - the narrowest, from below - the thickest. In the folded state, all parts of the ladder are as compact as possible, and are stored according to the “matryoshka” principle. The ladder can be extended to any height, there are clamps next to each step. There are also telescopic ladders with a hinge, allowing you to make a height-adjustable ladder out of them. The model is ideal in everyday life and a private house, as it occupies a minimum of space.
platform ladder
It is a fixed height design with comfortable steps and a large platform.
Often equipped with wheels for easy transportation around the warehouse or office. Suitable for picking orders or for work at a certain height. Maximum safety and comfort.
Dielectric
This is a ladder whose guides are made of plastic reinforced with fiberglass.
The main task of the product is not to pass electricity. There are one-, two- and three-section models, as well as with cable traction. It is strongly recommended to use them when installing and repairing electrical wiring and electrical equipment.
Conclusion
Currently, there are many options and models of stairs: there are both universal solutions and special ones made for specific applications. For the optimal choice, it is necessary to take into account what kind of work and in what conditions you have to perform. See the full range of models at store Dirs Stroy.
