The ladder is the essential element in the house to change a bulb, to paint a ceiling, in short for all the work that requires to gain height.
The ladder is also useful for gardening and tinkering outside the house. There is a scale adapted to each type of work. Overview of the different models and their rules of use.
Description of the different scale models
Many scale models are available on the market. Each of them corresponds to specific types of work. Whether it is wood, fiberglass or aluminum, you will necessarily find a ladder adapted to your needs.
The simple ladder or support
This type of ladder, which allows access to a limited height, is placed in support against a vertical wall. It can be used for both indoor and outdoor work. This is the simplest and most common scale.
The articulated ladder
Like the simple ladder, the articulated ladder is used to access limited heights. It leans against a vertical wall but can also be used as a mini-scaffold.
The sliding ladder
The sliding ladder exists in 2 or 3 planes. In 2 shots, it is intended to reach an average height, while in 3 shots, it allows access very high. The sliding ladder is used with a rope that slides the planes either upwards or downwards. It is a ladder that leans against a wall. It is more suited to outdoor work.
The transformable scale
The transformable ladder is the most versatile ladder. As its name indicates, this scale is transformed: it can at the same time be placed against a wall like the simple ladder, turn into a double ladder, like a stool, or be easily positioned on a staircase. Like the sliding ladder, it exists in 2 or 3 planes. The transformable ladder is particularly well suited for work in the middle of a room. This ladder can be used to reach large heights with its modular plans and can also be used for facade or pruning work.
The roof ladder
The roof ladder is intended for work on the roof (cleaning, installation, renovation, etc.). For maximum safety, this type of ladder is equipped with hooks to hold and lock on the ridge of the roof. Thus laid, the ladder adheres well to the roof without risk of falling.
This ladder allows for an individual to reach a mezzanine, attic or an attic in the house. It has the distinction of having flat and deep steps for the comfort of its use, but also for security concerns. Some models of mill ladders may have an optional ramp.
The telescopic ladder
The telescopic ladder is a ladder whose size (up to 3 meters) can be easily modulated according to its needs and use. It is very convenient to move considering the little space it takes once completely folded and thanks to its very light weight (about 10 kg).
How to choose a scale?
Depending on the height of the work
The main criterion for choosing a scale is the height of the work to be done or the spaces to be reached. There is a formula to choose the scale best suited to the use you want to make. It calculates the maximum height that you can reach standing on the ladder, positioned at the maximum on the fifth step before the top of the ladder: add one meter to the total height of the ladder.
Depending on its use
To access a limited height, that is to say within 5 meters, you will choose a simple ladder or an articulated ladder. For medium height, a 2-plane sliding ladder or a 2-plane transformable ladder is more suitable. Finally, to reach great heights, a sliding ladder or transformable 3-sided is necessary.
The position in which you will work also counts in the choice of a ladder. If you can only work against a wall, a tree, a facade, etc., you will have to choose a simple or sliding ladder.If you have the option of leaning against a wall or using the ladder as a stepladder, prefer a transformable ladder that is used in both positions.
Also consider the type of soil on which the ladder will be placed. On uneven ground, for greater safety, use a transformable ladder with a flared base.
The safety rules for using a ladder
The use of a ladder can be dangerous. It is important to respect certain norms and rules to take as few risks as possible. First, when making your purchase, be sure to choose a ladder that meets certain standards of strength and compliance. Thus, the French NF or European EN 131 standards guarantee resistance to a maximum load of 150 kg per bar. This gives you the assurance that the ladder has undergone a battery of tests to evaluate its resistance.
Then, for occasional or occasional use, choose a ladder with non-slip pads. Most simple ladder models have one. Ladders that allow access to great heights, such as convertibles, are in principle equipped with safety straps that prevent its separation and thus avoid accidents. It is also important to always check locking systems, especially on articulated, sliding or transformable ladders.
Another precaution to take with a simple ladder: never use it as a horizontal bridge between two points. In general, the basic safety rule when using a ladder is to always leave at least four steps above you to ensure the balance of the ladder.
The use of a roof ladder to carry out work on the roof of the house is particularly risky. To prevent any accident, it is necessary to equip you with a harness, a lanyard with a carabiner and a helmet. The ideal is to provide a shoulder bag with your tools to avoid coming and going on the roof ladder.
Depending on the work undertaken, think also about the material of the scale. If you use it for electrical work, take a ladder made of wood or fiberglass that are two electrical insulators.
How much does a ladder cost?
The price of a scale varies enormously depending on the model. The simple scale is the cheapest: you can find from 40 euros. Then, depending on whether it is transformable or sliding, depending on its manufacturing material, a scale can cost between 70 and 300 euros, and even beyond 500 euros.
