— Stairs. The traditional, familiar design of two parallel bars, between which the steps are fixed. To work on such a ladder, additional support is required — for example, a wall.

— Transformer ladder. A staircase similar in structure to the one described above, only has several sections connected by a failing hinge. This solution allows you to direct sections at any angle and even adjust the ladder to a zigzag shape, not to mention turning it into a stepladder.

— Stepladder. Stairs that need to be laid out. In the working position, the two parts of the ladder converge at the top at an angle, forming a characteristic "hut". In this case, the steps can be located on one or both parts of the stairs. However, this design makes the model much heavier.

— Mini ladder. A reduced version of the above stepladders: such ladders have less than 4 steps on one section, including the footboard located at the top and, accordingly, a small height.

— Tour tower. A device in the form of a fairly large horizontal platform raised above the ground by vertical supports. A distinctive feature of the product is the presence of a wide and stable platform. Tour towers are indispensable for work that takes a lot of time, since you can stay on the platform for hours. They can have a collapsible sectional or non-collapsible one-piece design. The vast majority of mo...dels are equipped with a wheelbase, so that the ladder structure can be quickly and easily moved from place to place. Some modifications allow you to change the height of the supporting structures, which allows the stairs to be stably placed on steps or any other uneven surfaces, with a sharp difference in height.

— Staircase with platform. A special kind of stair structures, equipped with a fairly wide platform. Most often they are involved in a certain technological process, large warehouses and other premises where there is no need to fold and hide the stairs themselves. Platform ladders can be used for many tasks, such as loading/unloading, repair and construction operations, etc. Almost all products of this type are large in size, heavy and non-separable, which imposes certain restrictions on their transportation, storage and operation. .

— Attic stairs. Stairs, specially designed to provide access to the attic, are distinguished by their peculiar design. Such a ladder is attached from above (from the side of the attic) to the attic hatch and, when folded, does not protrude beyond its dimensions. Thus, while the entrance is closed, the staircase is hidden and the whole structure has a neat appearance; and when opened, the hatch tilts down and the ladder can be expanded into working condition. Note that the attic hatch and the box for its installation in the attic opening are usually included in the delivery of such a ladder.

The total number of steps provided in the design of the stairs. This parameter is indicated rather for reference — the primary characteristic is still the height of the stairs. Note that when calculating the number of steps, the footboard is also taken into account (see below).

The maximum working height of the ladder. In models that do not have a footboard (see above), this parameter is usually indicated in the specifications for the total length of the stairs. It is worth noting here that the height of the upper step in such cases rarely corresponds to the working height to the nearest centimeter - firstly, the stairs are almost never strictly vertical, and secondly, the outermost steps are usually not on the very edge. However, in most cases this difference can be neglected. If the design provides for a footboard, then the height is measured along it.

When choosing a ladder by height, it should be taken into account that the longer the structure, the greater its weight and, usually, the higher the price. Therefore, buying a model with a long length makes sense only when there is a real need for it.

Ladder dimensions in fully folded position. The smaller they are, the more convenient the ladder will be in storage and transportation. Usually, only the length and width are indicated in the characteristics, because. the thickness of modern stairs is very small and in most cases it can be neglected; and in some models, only the length may be indicated at all — for the same reasons.

The total weight of the ladder. On the one hand, the lighter the model you choose, the more convenient it will be to carry, the less effort will be expended. On the other hand, lighter weight means less material used in the construction of the stairs, and this can adversely affect reliability. Therefore, it is worth choosing an option for this parameter depending on the planned features of the application. If the expected load on the ladder is significantly lower than the maximum, then you can not pay close attention to the weight. But if you have doubts and/or plan to work in difficult conditions with a heavy load, you should choose the more massive one from two models with the same characteristics. It is unlikely that this will seriously affect the cost of forces, but the risk of breakage and a dangerous fall will decrease significantly.
