SUSPENDING TOOL HAVING FALLING PREVENTIVE FUNCTION

摘要

PROBLEM TO BE SOLVED: To attain safe suspension to keep a unit horizontal by connecting a three- point suspending rope composed of two ropes to the tip of a pulling-up rope inserted into a pulley through an O ring, and fitting/inserting a safety switch to press and grippingly hold the rope by rotation of a claw to/into the base end side of the pulling-up rope whose direction can be reversed by the pulley. SOLUTION: A three-point suspending rope 4 is composed of bending bisected suspending ropes 2 in which hooks 23 are arranged in both end parts of ropes 22 having a prescribed length and which are inserted into an O-ring 5 and an adjusting rope 3 in which a prescribed length rope 32 having a hook 31 one one end is inserted into the O-ring 5 and whose one end is folded back and is superposed on each other and a thermally contractible tube 33 is fitted and inserted by a specific length and which can adjust a length between the O-ring 5 and the hook 31 by pulling the other end of the rope 32. In a rope 6, a long size rope is bound to a hook 61 hooked on the O-ring 5, and a safety switch 7 is fitted and installed through a pulley. A rotary hook 73 connected to the safety switch 7 is connected to the O-ring 5, and a unit U is horizontally suspended by the three-point suspending rope 4 hooked on the O-ring 5, and a fastening claw of the safety switch 7 prevents deviation of the suspending rope 6.
