<p>PROBLEM TO BE SOLVED: To enable the attachment/detachment of a plurality of hanging pulleys to/from a supporting wire. SOLUTION: A hanging pulley attaching/detaching jig 10, which attaches/ detaches cable laying hanging pulleys 12 to/from a supporting wire, has the shape of a bathtub, which is composed of a polygonal flat plate 26 and sidewalls 28 which are formed on the respective edge parts of the polygonal flat plate 26 integrally with the polygonal flat plate part 26. A plurality of grooves 34 (34A and 34B) are formed in the sidewalls 28, and the rear end piece of the cable laying hanging pulley 12 can be embedded in the groove 34. Further, hanging pulley holding holes 32 are provided inside the respective edge parts, and the leading end piece 24 of the cable laying hanging pulley 12 can be inserted into the hole 32. Leading end pieces 24A are inserted into the hanging pulley holding holes 32 which are formed inside the respective edge parts, and the rear end pieces 24B are pushed into the grooves 34 to attach a plurality of the cable hanging pulleys 12 to the hanging pulley attaching/detaching jig 10. After the 1st cable laying hanging pulley 12 is hung on the supporting wire, a long rid is turned to hang the cable laying hanging pulleys 12 attached to the adjacent side edges on the supporting wire one after another.</p> |
