<P>PROBLEM TO BE SOLVED: To provide a ceiling crane capable of easily pivoting a suspended load, even in the ceiling crane for suspending the suspended load using a plurality of hoists and a suspension tool. <P>SOLUTION: This ceiling crane comprises: a girder 3; travel rails 2, 2 on which the girder 3 travels via a girder traveling part 30; and a trolley 4 laterally moving along the girder 3. The trolley 4 is provided with a rotating body 5 via a pivot bearing 41. The rotating body 5 is provided with a plurality of hoists 6 so that a rotation center axis 41a of the pivot bearing 41 becomes the center of symmetry. The rotating body 5 is pivoted by rotating and driving a pinion 51 of a pivot driving mechanism 50 of the rotating body 5 meshed with a gear 42 formed on a circumferential surface of the pivot bearing 41. <P>COPYRIGHT: (C)2013,JPO&INPIT |
