  • Transportable, collapsible vehicle loading hopper
    Patent number: 4249848
    Abstract: A loading bin is carried on a wheel-supported transportable frame in a collapsed condition in which the upper filling end of the loading bin is below vertical height road clearances for highways. The bin can be elevated at the construction site so that its discharge end is above the height of the vehicles being loaded. The bin is filled by a cart traveling along a track from ground to an elevation above the bin with the track being deployed automatically upon raising of the bin. The cart automatically dumps its load into the bin upon reaching the filling end of the bin.
