A distinctive feature of the ladder – it can be located anywhere in the premises without additional support. This ladder can be either with unilateral or bilateral climbing; steel, aluminum and wood are presented on the market. A ladder can have three or more steps 3 steps or more. Such models are used in warehouses and in shops for construction and repair works, and just in everyday life. Then, the article discusses different line of products, the price of the models, the distinctive characteristics of the products of the German brand Hailo and the company Alterno.
Classification of step-ladders by type of construction
The modern market presents the following configuration:
- traditional L-shaped;
- tower tours.
L-shaped constructions – wood, steel or aluminium – also have several variants . They are either one-way (steps are only at one side) and duplex (steps are at both sides) climbing. They are equipped with working platform for the convenience of work at height. This may be the last step. Ladder-transformers are widely used. Such models occupy a minimum of space when folded. They can be used in multiple configurations. In particular, they can be used in the form of side march with the console (resembling letter “L”).
Universal model can act both as the direct march, and as the ladder. They have 2-3 segments, each of which is equipped with 6-8 steps. They are distinguished depending on the mechanism of folding. The segments of the telescopic structure are put forward and fixed with consistently established elements in contrast to the folding counterparts.
Platforms represent the supports for the flooring. They are used for work at low altitudes. When you need a big tall, you should use tower tours which have a similar design.
The used materials
|Aluminium||Light weight with sufficient reliability, no corrosion, practical, ideal for household use||Relatively high price|
|Duralumin||Quite durable material, reasonable price||Lower resistance than of aluminum and steel||An alloy of aluminium|
|Steel||High strength, reliability, suitable for professional ladders||Susceptibility to corrosion, steel structures have a larger weight than aluminum ones||Bolt connection or welding is used for attaching the treads to the supports of metal structures|
|Wood||Easier to handle than metal, maintainability, you can make a ladder with your hands||Great weight of the finished product, exposure to the environment||During the manufacture of ladders you should draw attention to the absence of knots in the wood, you need lacquer coating for protection from external influences|
Another possible option is the combined product. Due to the fact that the greatest burden falls on the supports, they are made of metal, and the crossbar is made of plastic or wood. When choosing a ladder you should check its stability. It influences the further safety.
The number of stages of the ladder
Models are different by the number of stages. The indoor use involves ladders with number of beams greater than 8. The products with two or three steps are recommended for domestic purposes. This is enough for hanging curtains, replacing a light bulb or getting something from the mezzanine.
Products with the number of beams from 4 or more are used in rooms with high ceilings. Such models will be in need when wallpapering or replacing ceiling lights. They are suitable for outdoor works. It is worth considering that the price can be high.
Ladders with wide steps will serve for domestic purposes. Polymer coating or thread is used to prevent slipping on the surface. This is convenient when applying the paint or plaster on the wall or ceiling. Often this ladder is equipped with a shelf for materials and tools.
What else does affect the reliability of the ladder?
When purchasing ladders need to see how rails are attached to the uprights of the structure. The most common way is to mount on the studs. However, a more reliable method is rolling. In this case, the metal rails are pressed into the supports and sealed.
The presence of the safety bar is not necessarily, but preferably; the angle between the segments affects on the stability of the structure: the bigger it is, the more stable the model will be.
It is important to make the unfolded ladder stable and not slide on a floor surface. That’s there are special tips made of rubber or soft plastic. The presence of restrictive straps is preferable to prevent the full unfolding of the ladder. If belts are not available, the angle of the working position of the structure is only held by the upper platform. So you need to make sure that it is firmly anchored.
