<P>PROBLEM TO BE SOLVED: To provide a safety apparatus for roof work, by which work position can be changed over the whole range of a roof slope face without changing the stretched position of a main rope stretched on the roof, thus enabling roof work to be safely and efficiently performed. <P>SOLUTION: A main rope 4 is stretched along a ridge 2 of a roof 1, and a rope winder 20 is slidably connected to the main rope 4. In working on the roof 1, a high-place work safety belt 50 is wound around the waste of an operator and a tip of a strip-shaped rope 23 taken out of the rope winder 20 is connected to the high-place work safety belt 50 to ensure safety. The work position of the operator can be changed over the whole range of the slope face of the roof 1 by moving along the main rope 4 of the rope winder 20 and by taking the strip-shaped rope 23 out of the rope winder 20. <P>COPYRIGHT: (C)2012,JPO&INPIT |
