When another lift vehicle is present in the front, as shown in FIG. 5, the relay 19R senses the current passed through the position transmission line 4a by the front lift vehicle and turns off the conductor 19M. As a result, no current flows through the electromagnetic motor 17, the drive pinion 10 loses its rotational driving force, and the traveling device 6 stops. Therefore, the lift vehicle of the present embodiment has an advantage that it does not collide with another lift vehicle even if another lift vehicle exists ahead.

When a person sitting on the seat 27 operates the brake operating means 28, the driving of the electromagnetic motor 17 is stopped, the stop brake 23 is operated, and the traveling device 6 is stopped. Therefore, even if another lift vehicle is present in the front, even if the lift vehicle does not stop, the passenger can stop the lift vehicle by operating the brake operating means 28. , Safer.

Further, in the present embodiment, the stop brake
Since 23 is to apply the braking force via the timing belt 21 different from the timing belt 15 hung on the electromagnetic motor 17, even when the timing belt 15 to which the drive pinion 10 is connected is broken. The lifted vehicle is highly safe because it can be stopped without running away.
