Abstract
A transportation system of a floated-carrier type according to the present invention has a guide rail cover extending in a longitudinal direction. The guide rail cover comprises a guide rail. A carrier is made to float, in a non-contact manner, from the guide rail, by means of floating device and is propelled along the guide rail by a transfer device. An electrical device and a battery for supplying a current thereto are mounted on the carrier. In this transportation system, a charging device is provided for charging the battery. The charging device comprises a first terminal connected to the battery, a charging power source located on the guide rail cover, and a second terminal, which is connected to the charging electric power source and can be brought into contact with the first terminal when the carrier is stopped at a predetermined position. When this occurs, the first and second terminals are brought into contact with each other, and the charging power source supplies power to the battery via the first and second terminals. Each time the carrier is stopped at the predetermined position, the battery can be charged, thereby enabling the carrier to be operated continuously over a long period of time.
