Patent attributes
The present invention provides an overhead travelling carriage with a hoist which suppresses transmission of vibration to an article during conveyance. A chuck mechanism 10 is provided in a hoist 7 to support the top of an article 4. A fall preventing mechanism 14 is provided to prevent the article 4 supported by the chuck mechanism 14 from falling. Movable members 18 are provided which can move in a horizontal direction so as to advance toward and retreat from the housed article 4. Each of the movable members 18 has an L-shaped side cross section that extends so as to cross the direction in which it advances and retreats. A horizontal portion 18a of the movable portion 18 acts as means for preventing the article from falling. Rubber dampers 19 are provided on that surface of a vertical portion 18a of the movable member which is closer to the article 4, so as to constitute members pressed against the article 4. Movable portions provided in the fall preventing mechanism 14 are composed of only rotationally movable portions.
