REPEATING DEVICE USED FOR DOUBLE SAFETY MEASURE IN HIGH PLACE WORK AND DOUBLE SAFETY MEASURE METHOD
To provide a repeating device which is attached to a main rope in a double safety measure in a high place work, which is simplified and light weight, and prevent falling of the repeating device from a main rope.SOLUTION: There is provided a repeating device 10 which is attached to a main rope in a double safety measure in a high place work which uses as a life line, a safety block 31 in addition to a main rope 20 connected to an operator, and which is connected to an operator through a lanyard 32 and to which the safety block is connected. The repeating device comprises: an annular part 12 for connecting the safety block and the lanyard; and hook-shaped parts 13 provided at least two places on the annular part to be attached to the main rope. The respective openings to be hooked to the main rope 20 in the adjacent two hook-shaped parts 13 are directed to opposite directions, and when the main rope 20 is a rope formed by twisting three ropes, and has a diameter of 18 mm, an attachment interval L1 of the adjacent two hook-shaped parts is 45-100 mm.SELECTED DRAWING: Figure 4
【課題】高所作業の二重安全対策においてメインロープに装着される中継装置を簡易で軽量とし同時にメインロープから脱落しない。【解決手段】作業者と接続されたメインロープ20に加えライフラインとしてセイフティブロック31を用いる高所作業の二重安全対策においてメインロープに装着され、セイフティブロックが接続されると共にランヤード32を介して作業者と接続される中継装置10において、セイフティブロック及びランヤードを接続するための環状部12と、メインロープに装着するために環状部における少なくとも2箇所に設けられた鉤状部13と、を有し、隣り合う2つの鉤状部13におけるメインロープ20に引っ掛けるための各々の開口が互いに逆向きでありかつメインロープ20が三つ打ちでかつ直径18mmである場合、隣り合う2つの鉤状部の取付間隔L1が45〜100mmである。【選択図】図4
