Important points in choosing a ladder:
Strength: One of the main design features of ladders is the maximum weight bearing capacity, which according to international standards should be about 300 pounds or about 137 kg weight bearing capacity. Of course, this ability depends on the material used and also the design of the ladder.
Height: The second important indicator when buying a ladder is the amount of height it gives you. This height starts from 50 cm and depending on the type of use and the height of the walls of the house is up to about 4 meters, however, in today's houses about 2 meters, a height of about 6 steps seems to be enough for a ladder.
Material: The next item is the ladder body, which must bear the weight of a person in addition to the weight of his equipment. Of course, keep in mind that the material used in the ladder, while strong, must also be light and portable.
Safety: Self-safety includes the strength of the body, the placement of the bases, weight balance, surface and area of the stairs. The strength of the body in the case of ladders should be such that it is resistant to weight and is placed on the ground without static and stable displacement. The connection of the bases to the body should be such that both bases are exactly parallel to each other and have the highest contact surface to secure the ladder to the ground well. The corners of the pedestals should have protrusions or appendages that prevent movement and slipping and secure the ladder to the ground.
Area: The next article is about the area and surface of the stairs. The area of the stairs and their distance from each other should be in a way that allows the user to move and rotate around. Also, the distance between the stairs should not exceed 35 cm, because walking at a greater distance It will be difficult. As for wall ladders, you should pay attention to the strong material of the stairs and the stability of the body, because in case of any movement and response of the body to weight movements, it increases the probability of falling. So choose a body that has the least flexibility and has an acceptable thickness and is compact and strong.
