At least some of the rungs are equipped at their outer ends with transverse distance pieces, the free ends of which are intended to lie against the wall or the like. The rungs and the distance pieces are made of one piece of rod material, and that the rungs and distance pieces are connected with one another over a part which extends from the outer end of the rung and upward in the installation position of the ladder. Pat.The present invention relates to an improvement in a ladder of the kind which has a central rod from which stick out rungs in opposite directions. The ladder is intended for various uses, but principally for installing in wells, tanks and the like, as well as for use as a fire- or rescue ladder.
