One end of a hanging wire 23 is connected to an end part of each support rod 27, and a hook 28 with an untwisting mechanism is provided to the other end. One end of a remote operation rod 24 is connected to the hook 28. The slinging tool is provided with a hanging rod 25 penetrating through the central part of the support 21 in an advanceable and retractable manner, provided with a hanging ring 32 integrally at one end, and having at the other end an opening and closing operation plate 33 for the plurality of support rods 27 arranged in the tube bundle form. A plurality of guide grooves 34 guiding the respective support rods 27 are formed on outer peripheral sides of the opening and closing operation plate 33. In the opening and closing operation plate 33, the length from the central part to a bottom part of each guide groove 34 is set to be larger than the length from the central part of the support 21 to the pivot shaft 21a. |
