  • Carriage conveying equipment
    Patent number: 4972917
    Abstract: A carriage conveying apparatus has a loaded carriage to be conveyed, and a driving vehicle for coupling, towing and conveying the carriage from below the carriage. Since the vertical load of the carriage is transmitted to the driving vehicle, controlled to a proper magnitude, the driving vehicle may be reduced in size and weight, and it is also possible to have stable travel if the carriage is empty. By designing all three wheels so as to be driven and steered, sideways and spin-turn motions are realized. By providing recognition marks and detecting means, it is possible to position the driving vehicle accurately if the setting position of the carriage deviates.
