PURPOSE:To perform high-speed and safe transportation with minimum energy consumption by running a vehicle by gravity along a transportation passage in which the intermediate position is lower than the starting position and terminal position, and using external driving force as an auxiliary means. CONSTITUTION:A transporation passage 1 connecting points A, B has a point C of the lowest level on the way, and sections between points A, B and C form down grade of vertical curve such as parabola etc. Horizontal sections are provided to stop a vehicle 2 in the extension of both ends A, B of the transportation passage 1. The vehicle 2 is run by gravity in the direction of down grade along the passage 1, and after passing the point C, goes up to a specified position in the up grade section. Thereafter, the vehicle arrives at an object position being driven by external force. Various types of external force such as a chain conveyor, a wire rope, a motor mounted on the vehicle itself can be applied. |
