Abstract

PURPOSE:To facilitate work itself and to efficiently observe the whole state of an overhead cable, by allowing an apparatus main body to run along the overhead cable and driving a television camera in addition thereto. CONSTITUTION:At first, an apparatus main body 1 is suspended from an overhead cable C so as to be freely runnable along the cable C. Subsequently, an observer operates the transmitter 12 in his hand to operate the main body 1. Whereupon, the main body 1 begins to run along the cable C and a television camera 8 is operated to take the image of the outer surface state of the cable C. At this time, the states of the both left and right side surface of the cable C are together photographed on one picture by two borescopes 6, 6 to be recorded on a video tape recorder. Therefore, a recording tape is taken out from the video tape recorder after the finish of work and regenerated at a separate place to make it possible to observe the state of the cable C in detail at any time.
