Abstract

A ladder (10) has rails (11) and wide rungs (12). The wide rungs (12) are designed as C profiles which are open at the bottom and have a treading surface (16) which is protected against slipping. The rails (11) in the traction zone have either a simple, correspondingly dimensioned limb or a box profile which increases the moment of resistance. In this case, it is possible for identical wide rungs (12) to be employed in ladders of different design. An optimised modular production can be provided. <IMAGE>
