Raise the hanging device 17. That is, if the suspending device 17 rises horizontally, the second sensor 65 on the one side in the X direction coincides with the third sensor detecting portion 75 of the vertical guide member 12 on the one side in the X direction, and at the same time, the second sensor on the other side in the X direction. Since 65 coincides with the first sensor detecting portion 73 of the vertical guide member 12 on the other side in the X direction, the suspending tool 17 moves horizontally due to the lighting of the first lamps 93-1 and 94-1 as described above. I can confirm that.

When mounting the cradle 13, the guide pin 66 may be inserted into the second vertical guide portion 41 of the vertical guide member 12 in the same manner as described above, and thereafter, the operation opposite to the above may be performed. At this time, since the connecting member 51 of the cradle 13 has a plate shape and is inclined with respect to the vertical direction, the connecting member 51 is in contact with the upper portion of the hook 55 of the cradle 13 already placed, and serves as a guide. Cradle 1 that has already been placed smoothly because it fulfills
Can be placed on top of 3. In addition, the cross member 5 of the upper cradle 13
The 0 is in contact with the upper portion of the vertical member 53 of the lower cradle 13, and the cradle 13 is sequentially stacked.

[0060]

As described above, the guide bar mechanism can engage and disengage the hanging bar 19 in the downward recess 56 of the hook 55, so that the cradle 13 can be operated without finely operating the hanging bar 17.
Can be slung on the hanging tool 17, and its operation becomes easy. Further, since the operator can confirm the position of the guide pin 66 by the monitor panel 23, the operator can check the position of the guide pin 6.
The crane 14 can be operated while confirming the position of 6.
