The invention related to a platform made of the extruded self-carrying profiles supported by the supporting frame fixed to the inner interior walls. The platform floor is made either from the single individual profiles or is made from the pre-assembled or pre-fabricated segments to be joined together on the site. The platform parts are made of a light and rigid stiff material such as aluminium, aluminium alloys, preferably by extrusion or any suitable composite. The single profiles, the smaller pre-fabricated sections of light material are much easier to transport and assemble. Alternatively the platform is also provided with circumference floor movable segments mounted at its perimeter that might extend outside of the floor and thus allow elimination of gaps between the inner interior walls and the platform circumference. This prevents the falling through down e.g. the service tools and/or personnel. |
