ABSTRACT:
A load transport equipment having self-propelled trucks travelling on a predetermined route so as to transport a load by the truck, wherein an encoder is connected to a motor and the pulse number from the encoder is counted by a counter, the counted value being optically transmitted toward another self-propelled truck following the front self-propelled truck on the predetermined route, the following self-propelled truck receiving the counted value from the front self-propelled truck to obtain a difference between the received counted value and that of the following truck, so that the travel speed of the rear self-propelled truck is controlled on the basis of the difference so that the running speed is controlled in accordance with the distance between the trucks thereby preventing a rear-end collision.
