PROBLEM TO BE SOLVED: To prevent a jig tool to be used from falling under a car or into a hoistway even when an apparatus such as a speed governor rope is arranged immediately below an object when working on the car.SOLUTION: A jig tool fall prevention device includes: a sheet-like fall prevention part 18 for receiving when a jig tool 11 falls; a gap 20 formed at the fall prevention part 18 so as to sandwich a speed governor rope 7; a fastener 19 for closing the gap 20; a hand hook part 22 which can be wound around the speed governor rope 7, and which is mounted on the fall prevention part 18 in such a manner that one end 22a is not attachable/detachable and the other end 22b is attachable/detachable, respectively; and a suction part 17 for attachably/detachably mounting the fall prevention part 18 between a beam 9 for mounting a speed governor 6 and a handrail 13 on a car 8. Also, it includes an outer side fastener 23 for closing an outer edge of the fall prevention part 18 in an openable manner and making it into a bag shape, so that the fall prevention part can be made into a bag shape by closing the outer side fastener 23.SELECTED DRAWING: Figure 5
【課題】かご上で作業する際、対象物直下に調速機ロープのような機器が配置されている場合でも、使用する治工具のかご下あるいは昇降路への落下を防止する。【解決手段】治工具11が落下したときに受け止めるシート状の落下防止部18と、調速機ロープ7を挟み込むために落下防止部18に形成された切れ目20と、切れ目20を閉じるファスナー19と、調速機ロープ7に巻き付け可能であって、落下防止部18に一端22aは着脱不能、他端22bは着脱可能にそれぞれ取り付けられる手掛け部22と、調速機6を取り付ける梁9とかご上8の手摺13間に落下防止部18を着脱可能に取り付けるための吸着部17と、を備えた。また、落下防止部18の外縁を開放可能に閉止し、袋状にする外辺ファスナー23を備え、外辺ファスナー23を閉めて袋状にすることができるようにした。【選択図】図5
