By the way, the position of the load on the load placement part in the vehicle movement direction with respect to the vehicle body is appropriate due to the position error when transferring the load from the station to the load carrier and the position shift due to vibration during traveling. There is a risk that it will be displaced from the position, and as a result, even if the car body is stopped at the proper position for the station, the position of the loaded load on the station will deviate from the optimum position for load delivery, and the load will be delivered properly. There was a fear that it would be difficult to do.
