  "abstract": "Fall restraint equipment comprising a mobile access unit having a mobile platform portion, a ladder portion, and a cage portion. The components of the fall restraint equipment are formed from butterflying, lasering, cutting, bending, and/or stamping continuous pieces of tubular and sheet metal. The components of the mobile access unit are modular and include adapters of varying height that cause the mobile access unit to exhibit varying height. Also, the mobile access unit is adaptable so that it can roll in a first direction of orientation of the ladder or a second direction perpendicular to the first direction.",
