Abstract
An mobile equipment boarding ladder includes a pair of hinged mounting brackets attached to the mobile equipment at a first end. A ladder step is attached to the second ends of the hinged brackets via a pair of pivot mechanisms. The hinge pins and the pivot mechanisms are substantially parallel so that the entire ladder can fold and collapse against the side of the mobile equipment in response to an external force, such as an obstacle. The hinged brackets can be self-centering via gravity, a spring, or both. A pair of flexible straps are attached to the second end of the hinged brackets, and hang vertically from the brackets. A pair of lower pivot mechanisms and a lower step are attached to the lower end of the straps, oriented in the same manner as the first pivot mechanisms.
