Question:
>Answer: A scale for each type of wall and by activity
There are different types of scales. Simple ladders, made up of a single plane, are used to rest on a vertical wall, while transformable ladders can be used in several positions: resting or freestanding, like a stepladder. Ladders fitted with level adjustment work with offset walls, like a staircase. Transformable ladders with three planes, which allow you to work without leaning, are suitable for activities such as picking; sliding ladders allow you to reach great heights, while articulated ladders are used in many positions (freestanding, in support, platform, etc.). They are easy to transport. video id = "0" / Our practical decoration videos
