However, in the above structure, a large external force acts on the vertical frame and the horizontal frame of the frame type frame, that is, the weight of the vehicle mounting table acts on the vertical frame via the wire drum shaft. Since the reaction force at the time of operation of the lifting drive motor and speed reducer acts on the horizontal frame via the gantry, both frames had to be strong and sturdy, which was an uneconomical structure. .

Further, since the chain wheel becomes large due to deceleration by driving the chain and the chain wheel projects from the wire drum, it interferes with various members attached to the gate frame side when the frame frame traverses. There is danger. Therefore, the present invention provides a lifting pallet drive device which has a simple structure of the traverse carriage and which does not interfere with various members on the column side when the traverse carriage moves.
