SOLUTION: This commodity carrying device comprises a refuge rail 41 and the carriage 4 to be moved along the refuse rail 41, wherein current collectors 38 are provided for making the carriage 4, when pulled up, directly or indirectly engage the refuse rail 41 to prevent the carriage 4 from being moved up. A portion of the refuse rail 41, opposed to the current collectors 38, is formed as an upward movable rail portion 43, and so the carriage 4 can be simply removed upward together with the upward movable rail portion 43.</p> |
