In the figure, an overhead crane trolley 1 runs above a girder 2 of the overhead crane main body. A telescopic rod 3 for changing the position of the hanging hook is provided at both ends of the lower part of the girder 2 of the overhead crane main body, and this telescopic rod 3 is driven by a telescopic rod drive device 4 installed inside the girder 2 of the Otsuki crane main body. be done. The telescopic rod 3 is connected to a rotating rod 5 for changing the position of the hanging hook via a pin 1-7. A rotating wheel support rod 8 is connected to the tip of the rotating rod 5 via a pin joint 7, and a wire rotating ring 6 for guiding a wire 9 is installed in the center of the rotating wheel supporting rod 8. Furthermore, a hanging hook 10 is attached to the tip of wire A7-9.

Move the J1 crane trolley 1 over the top of the girder 2 of the overhead crane main body to the farthest side of the building limit Wt! Stop where you want. Next, after winding up the wire 9 and positioning the attached hook 10 above the rotary wheel support rod 8 and the wire rotary wheel 6, the telescopic rod drive device 4 is used to change the position of the hanging hook on the retractable rod 3.
is retracted, and the rotary wheel support rod 8, which was located closer to the building limit than the hanging hook 10, is moved to a position opposite to the building limit side than the hanging hook 10 (position 78 in FIG. 1).
