Today, sectional aluminum ladders are an almost irreplaceable structure that is used both in everyday life and in production.
In this case, the staircase can be made in several structural types, unfold or move apart.
Aluminum stepladders, ladders
What is more important, the use of a session structure always allows you to work on it in different conditions, including as on a conventional wooden ladder.
Aluminum can cause associations with light and fragile metal, however, in the manufacture of stairs, not just aluminum is used, but an admixture of an alloy of metal with magnesium, which makes the product both strong and light, and of course, does not allow corrosion to undermine the racks.
Appointment
It is possible to carry out a kind of division of the staircase structure according to the type of purpose, since there are only two of them:
- Household... Such stairs are commonly used in private homes and summer cottages. Moreover, aluminum two-section ladders are perfect for both gardening and construction work in low-rise construction. It can be renovation, facade decoration.
- Professional... This type is used for outdoor work, as a rule, and can be suitable for use with power grids. Special plugs on these ladders not only prevent slipping, but also drain the electrical charge.
In addition, professional ladders always have a higher working height than household ladders. Such a ladder can be equipped with special wheels to move the entire structure along the wall, while the worker is on the steps and does not descend.
Requirements
Considering that aluminum single-section ladders, like two-section ones, are intended for work in which a person will be at a height that is dangerous to health, the main requirement is safety.
It can be regulated as follows:
- The structure must be stable. For this, the lower ends are equipped with either sharp tips, in the case of use on the ground, or with special shoes that prevent the ladder from sliding over the surface.
- Must bear the load. According to the requirements of GOSTs, in relation to this type, the steps of the stairs must withstand a weight of up to 150 kg.
- Support beams and steps must be free of burrs and cracks.
- If the product is equipped with wheels for movement, there must be a locking mechanism that prevents the wheels from spinning in a static position.
- If it is necessary to carry out work under voltage, the aluminum base must be reliably grounded and equipped with special rubber pads.
- The rungs of the stairs should be made of high quality profiled alloy.
- The steps must be reliable, wide, and provide comfortable ascent and descent.
In addition, the instructions for working with a two-section structure allow you to increase its height. However, this is not the only advantage of several sections.
Sections
Today there are several types of folding and sliding structures that can be classified by the number of sections. Moreover, the division depends precisely on the sections, here the value is from one to four, and the latter type can be designated as universal and telescopic.
If we consider each type, then the following parameters can be noted:
- An aluminum single-section ladder, or extension ladder, should rest on a vertical surface at an angle of 75 degrees. It is the simplest sectional type, simple, lightweight and compact. Length up to 4.7 m, load up to 150 kg.Weighs up to 8 kg and is equipped with 7-17 steps.
- Two-piece. This is a more versatile option, and it can be used both as an extension and as a sliding one. Among the advantages can be noted the ability to adjust the height. Length up to 4.7 m, load 150 kg, structure weight up to 20 kg, number of steps from 7 to 17.
- Three-section aluminum ladders. In this version, there is the ability to combine several structural moments at once, namely the functions of an attached structure, a step-ladder and a two-section type. This approach makes this type in demand not only in everyday life, but also at large construction sites.
At the same time, there is a lot of do-it-yourself work that can be done precisely with three-section staircase... It is also worth noting here the high stability rates and special protection mechanisms against unexpected folding during operation. In addition, high functionality is achieved by the ability to adjust the height.
The height is 4.7 m, and the height of the work carried out can reach 10 meters. The load is 150 kg and the weight of the product itself is up to 53 kg. The number of steps, from 7 to 20.
- Four-section. This type can also be called a "transformer". Here we can talk about the largest number of modifications, and at the same time about the most compact folded size among all other analogues.
From the point of view of functionality, a four-section aluminum ladder can play the role of a free-standing, attached, or two-section ladder, or it can be transformed into a platform.
The position of the entire product can be adjusted using steel hinges. With a special lock, the staircase structure is fixed in a certain form, layout.
Length up to 1.4 meters, in working order up to 4.7 meters. The load can be maintained up to 150 kg, the weight of the ladder is 17 kg, the steps are from 3 to 5.
It is important, in addition to all sectional options, it is possible to present a telescopic and multifunctional design.
Telescopic type combines both a ladder and a stepladder at once. In the position of a stepladder, we can talk about enhanced stability, which is due to a wide base, which practically excludes the possibility of overturning.
With the help of lateral clips, the height of each side of the march can be adjusted, this allows you to work with different surface heights when you need to place your knees on the floor, and, for example, on steps.
Sometimes this option is equipped with additional tool holders. When fully assembled, everything can be placed in the trunk of the car, which once again proves functionality and compactness. Height 3.5 m, working height -3.1 meters, withstands loads up to 120-140 kg, weighs up to 15 kg.
It is worth noting that this is a rather expensive option, and its price can reach 14 thousand rubles, but this is due precisely to the design features of the product.
Conclusion
A wide range of applications of any type, whether it is an attached sectional or a sliding aluminum four-section ladder, allows you to carry out a huge amount of work. This is both construction and repair work, in the garden, using various stairs, you can conveniently harvest or prune branches.
As for the two-section version, its popularity is easily explained precisely due to its ease of use. Functionality, and we can also talk about it here, is that the product is used equally conveniently both as a side march and as a step-ladder.
That is, for certain requirements and for the performance of work and on the surface on which the march will rely, you can easily change the modification.
Output
Some types of sliding staircases can be assembled independently, even using aluminum blanks.However, the most correct decision would be to purchase a finished product, since there is plenty to choose from.
The choice can be made for a certain direction in the work, where the product will be used. In the video presented in this article, you will find additional information on this topic.
