Folding portable ladder, formed by two frames articulated in its upper part, in the form of scissors, being one for support of the steps and the other for support in position of use, which is characterized in that the support frame of the steps is constituted by two contractable beams formed by tubular elements coupled to each other telescopically, both beams being joined at their upper part by means of a tubular element in the form of a bridge provided with a sleeve in the form of a grip on its upper part; to each of said sections a step is coupled by articulation of these in corresponding arms projecting from the upper part of said sections, by means of a longitudinal guide device that allows them to rotate and a transverse displacement with respect to the longitudinal members, allowing the abatement of the themselves against their respective telescopic sections that serve as support.
