Abstract

New ladder beams, characterized in that each stringer of the ladder between which the rungs are arranged, is constituted by different tubular sections connected to each other, including in telescopic form and there being means of fixing the emergence of a tube in relationship with the other immediate, the set of all which are strongly between each other by means of a strut that is made to pass through skew that emerge perpendicularly from them as well as support pulleys and sliding cable at convenient points, so that the cable, starting from a fixed point of the lower section, connects the sections and returns to the same section of the starting point, by collecting the impeller provided with the appropriate actuation sea of the winding drum and tensioning the cable and ratchet of the drum.
