Self-propelling truck

Abstract

Abstract PURPOSE:To eliminate the need for the exchange of a battery for a self propelling truck by mounting a feed rail for a current collecting rail to the whole or one part in the travelling path of the self-propelling truck. CONSTITUTION:A current collecting rail 2 is set up to the base of a self- advancing truck 1, and a feed rail 3 is installed to the travelling path of the self-propelling truck. When there is not feed rail 3 on the travelling path of the self-propelling truck, a controller 7 for a stepping motor 9 and a motor 8 for travelling is supplied with power from a battery 6 through a power changeover unit 5a. When there is the feel rail 3 on the travelling path of the self-propelling truck, the battery 6 and the controller 7 are fed with power from a collecting brush 4 through power changeover units 5a, 5b. Accordingly, the exchange of the batteries for charging is unnecessitated.
