ABSTRACT:
An access ladder configurable from an extended position for providing access to a structure and a stowed position. The access ladder comprises an elongated first member having a first step extending laterally therefrom. An elongated second member is associated with the first member and configured for translational movement relative thereto and has a second step extending laterally therefrom. A link extends between the second member and the structure such that rotation of the first member moves the second member translationally relative to the first member, thereby moving said at least one second step towards said at least one first step.
