  • Patent number: 5542495
    Abstract: A mobile work and servicing platform trailer is disclosed. The platform trailer can include a roof section that is formed from a metal grate with openings therethrough. A first level of storage hoppers located beneath the roof section catch debris passing through the grates. Screw-augers located beneath the first level of storage hoppers can pass debris passing through spigots on the undersurface of these augers to troughs with screw-auger inside the troughs. Rotation of the screw auger causes the debris to move to other spigots which pass the debris to a second level of storage hoppers. The roof is vertically raisable from an initial low position to various heights. Winged side panels on the platform trailer rotate along hinges on opposite sides of the roof section. The outer edges of side-panels are raisable to the same height as the outer edges of the roof section and up to approximately thirty to forty degrees angled above the roof section.
