Foldable manual ladder, which is essentially characterized by being a strong and lightweight assembly, preferably composed of metal tubular elements, divided into stringers and steps, the first articulated with each other, at least, by a midpoint to allow the folded one half over the other, while the second are determined by two pieces that are also articulated to each other and their extremities to those stringers, all these joints are arranged so that the ladder can contract laterally exerting pressure on such stringers, to approximate them, which is possible due to the mobility or play of the aforementioned steps.
