<p>This invention is an improvement over prior scaffolding and ladder systems. Accordingly, a main object of the invention is the provision of improved conveyance of personnel to a given location and a precisely positioned elevation relative to a structure, aircraft or edifice, with rapidity, facility, and safety. In addition, the invention affords a reliable, stable platform for use at thedesired elevation, and facilitates safe and rapid egress from that location under ordinary and exigent circumstances. Unlike a ladder, the Height Adjustable Rescue Assault System, or HARAS, provides a stable platform regardless of the nature of the terrain upon which it is deployed, since it is attached to, and has as its'base, an inherently stable vehicle. Although similar in working surface area to a scaffold, the HARAS is much more mobile than a conventional scaffold, in that it can be driven to, set up at, and utilized at a variety of locations in a matter of seconds. The invention's removable/retractable side running boards and removable rear platform, with horizontal surface of high traction aluminum weep decking enables personnel to ride in an elevated position alongside the system during operation. Sectional construction adds to the systems' portability and flexibility.</p> |
