Title: Safety-operation partitioning belt device
Inventor: SUZUKI TAKEO
IPC: E01F13/00
Filed: 2001-10-15
Abstract: PROBLEM TO BE SOLVED: To solve the problem that the authorized personnel are called together and time is required and the places of driving must be investigated so that a cable buried near a track is not damaged because a safety rope is stretched in approximately 3 to 5 spans, using electric poles on the side of a railway line as supports, approximately four piles are driven between the electric poles and a hanging-down is prevented and an operation is conducted. SOLUTION: A belt woven in a narrow width is adopted in place of the safety rope, and wound on an exclusive winder and used. The belt is formed in a yellow or black striped shape, and the belt is lighter than the rope, is not tangled because it is housed in the winder, is also transported easily to a site and is not stained because it is wound in the case of nonuse. The belt is not hung down by a tension by a winch in the case of a stretching among the spans because of lightweight, need not be supported in an intermediate section and damages no buried cable. Since it has a width wider than conventional ropes, visibility from a long distance is improved.
