ABSTRACT:
An intermodal transportation system for hauling bulk materials, particularly municipal solid waste, by rail and truck utilizes multiple rectangular, open-top boxes each having a removable lid. The system includes a forklift with an articulated frame actuated by hydraulics which engages channels formed in the box or in the lid. Lock bars on the box are clamped by locking members carried on the forklift to hold the box on the forks during an over-the-side dumping movement. The forklift empties the box with a roll-out motion combining a forward rotation of a lifted box with a backward movement of the box. A reinforced flatbed railcar receives up to four 21 foot long boxes and lids with a total carrying capacity of up to 100 tons. Each car contains upright corners that guide the boxes onto the railroad car and then restrain it. The containers are flush with the upper surface of the railroad car when engaged in the corners. A tractor trailer with a tilt-up roller bed and winch hauls the boxes on highways.
