A B S T R A C T The disclosure relates to a ladder set with mutually interconnectable sections which are disposed for varying the effective length of the ladder and which comprise two side pieces (1) and a number of rungs (2) fixedly disposable therein, in which both the side pieces and the rungs are manufactured of a profiled material. The side pieces have longitudinal, substantially enclosed pockets (4) for accommodating longitudinal projection members (3) on an adjacent section. The ladder is designed so as to be manufactured as an easily assembled kit and so as to possess extremely good resistance forces to the composite and extreme loadings which prevail when the ladder is in use. The ladder is characterized in that the rungs (2) are of closed cross- section with non-rotational symmetrical cross-sectional configuration, and that each end of the rungs has at least one projection (15). The projections consist of protruding portions of the wall material (14) of the rungs and are torsionally rigidly disposable in corresponding recesses in the side pieces. The rungs are urged against the side pieces by anchorage means (16) discrete from the projections.
