Document Type and Number:
Japanese Patent JPH1185282
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To enable a truck to gradually reduce the speed and stop by providing the rear wheel indication frame of a precedent truck with the projector and reflection tape of a far-distance sensor and the front wheel support frame of a following truck with the photodetector of a far-distance sensor and a short- distance sensor, and providing an approach stop sensor in front of the following truck. SOLUTION: The rear wheel support frame 5 of the precedent travel truck Cf is provided with the light projector s1 and the front wheel support frame 5 of the following truck Cb is provided with the photodetector s1' opposite the projector. The rear wheel indication frame 5 of the precedent travel truck Cf is provided with the reflection tape 10 and the wheel support frame 5 of the following truck Cb is provided with the short-distance sensor s2 opposite the tape. The approach stop sensor s3 is provided in front of the following track Cb. When the photodetector s1' receives the light from the projector s1, the travel speed of the following truck Cb is reduced from a high speed to an intermediate speed and when the short-distance sensor s2 receives reflected light from the reflection tape 10, the speed is reduced to a low speed; when the approach stop sensor s3 detects the travel truck Cf, the truck stops.
