<p><P>PROBLEM TO BE SOLVED: To provide a crane device that can effectively use energy generated by the operation of a crane device. <P>SOLUTION: Only when winch drums 3a, 3b, 3c rotate by delivering wires 4a, 4b, 4c, the rotation of the winch drum 3a, 3b, 3c is transmitted to a generator 12 by a one-way clutch 11 for rotational driving and generation. The generated electric power is used for operating electrical equipment 16 using a control section 13 and a battery 14. When the winch drums 3a, 3b, 3c rotate by winding the wires 4a, 4b, 4c, the rotation is not transmitted to the generator 12, and therefore, an excess load is not generated while the winch drums 3a, 3b, 3c rotate though being provided with the generator 12. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
