Multifunctional 3-section ladder: design features and technical purpose

When performing construction and installation work, it is often necessary to perform certain operations at a height. Previously, ordinary stepladders or any available means were used to conveniently access such surfaces. However, in our time, a universal 3-section ladder is used for such work.

Design features and technical purpose

First of all, it should be noted that there is several varieties similar devices. They differ in the material of their manufacture and the presence of additional elements. At the same time, a standard three-section ladder 3x12 has all the qualities necessary for performing work, and additional components only expand them.

Advantages

Aluminum three-section ladders have a lot of advantages over conventional stairs, for which they have become so popular:

• These assembled products have small dimensions, which allows them to be conveniently transported and stored. It should be noted that such ladders are made from a special aluminum alloy, which is not only very durable, but also quite light.
• Various installation options allow the technician to use the device with maximum efficiency and organize their work more productively.
• Separately, it should be noted that the 3-section step ladder has a number of additional accessories, including such important ones as rubber stops and an installation shelf.
• Also, this design has an additional section that is not fixed on the main product and can be used independently.

Advice! When choosing an aluminum step ladder, the main criterion is its convenience and practicality. However, it is also worth paying attention to the dimensions, since large and bulky structures can only get in the way when working indoors.

Direct installation

In this position, all sections of the ladder are installed sequentially in one line. This achieves its maximum length. It is worth noting that the strength and stability that a 3-section ladder has in this position is significantly higher than that of other devices.

A similar installation method is used for the installation of air conditioners and heaters, as well as for small-scale local work. In other cases, it is more rational to use scaffolding.

Advice! With such an installation, it is imperative to check the reliability of the surface on which the ladder is located, since it will use only two supports for stability.

Basic position

This type of installation is considered the main one, since it is it that is most used by modern builders. For its implementation, two connected sections are laid out in the form of the letter L, and then a separate element is adjoined to them, setting it to the required height. Also, it is for this installation method that many different auxiliary devices have been developed.

It is worth noting that 3 x sectional step ladders in this position have many positive features that can affect the quality and speed of work:

• They are as stable as possible and allow you to carry out installation without a safety assistant.
• Their maximum height can reach 5 meters, with a section length of 3 meters, but the angle of inclination should also be taken into account.
• Thanks to the extension shelf at the required height, you can place the tool you need for work, which will avoid constant descents behind it.
• Also, such a device is used to create a level platform on which to stand.
• Usually a 3-section ladder is supplied with feet with rubber plugs, but if desired, they can be replaced with wheels, which will allow you to move the product without disassembling it.

Advice! In this installation method, the maximum length is achieved by extending the individual element to the required height. However, it must be remembered that the structure will become unsafe if the weight of the exposed element exceeds the main support. Therefore, the masters do not risk nominating it for more than 23.

L-shaped position

This type of installation is no less popular, especially when working indoors. In this case, 3-section stairs usually do not use an attachment element, which in this case only makes the entire product heavier. However, it is this design that was taken as the basis for creating the device and will always be used by the masters.

It is worth noting that a real professional will always be able to independently come up with several types of ladder installation, which are not indicated by the instruction manual. At the same time, even some craftsmen create special devices that help them solve individual problems and cope with specific work.

Advice! When creating independent ladder positions, it must be remembered that the connecting elements and fasteners have a certain strength and, if handled incorrectly, they can break. Therefore, do not violate the instructions of the instructions supplied with the product.

Manufacturing material

Usually, this type of stairs is made of an aluminum alloy, the price of which is quite high, but its strength and lightness endow the structure with a lot of positive qualities. However, quite often, high-altitude work is associated with the danger that is created by the proximity of power lines, which can lead to electric shock. Therefore, it is impossible to use metal products in this case.

For these purposes, you can try to secure the stairs with your own hands, or you can purchase a ready-made structure made of dielectric material. It will cost a little more, but it will allow you to work under power lines, without the risk of turning into a lightning rod for a current.

Please note! Fasteners and accessories have a very strong effect on the functioning of the structure, therefore, when purchasing a ladder, you need to pay special attention to them

Advice! Do not neglect safety precautions when working at height, and especially if there are high-voltage lines nearby. Reasonable care can save life.
