<p>An object of the present invention is to provide a crane device (1) suitable for handling a wrapped crucible (2), which crane device (1) is capable of realizing mechanical handling of the wrapped crucible (2) by way of a machine without manual work. In view of this, the present invention provides a crane device (1) adapted to be capable of making reciprocal movements along a path (6) between a position above a lifting-up point where a wrapped quartz glass crucible (2) is placed and another position above a putting-down point where a packing container (4) is placed and ascending to/descending from the path at each of the lifting-up point and the putting-down point, the crane device (1) having: four arms (17a-17d) extending in the ascend-descend direction and disposed at apexes of a quadrangle such that two arms paired (17a,17c;17b,17d) on a diagonal line of the quadrangle are movable to advance to/separate from each other; and a claw (18a,18d) provided at a rear end of each arm (17a-17d) to extend in the advancing direction of the arm.</p> |
