PURPOSE:To facilitate work by providing a large gondola-assembling hanging rope to be hung from a cable by a small gondola through a mounting jig of a small gondola-hanging rope, arranged in a predetermined position of the cable, so as to assemble a large gondola. CONSTITUTION:Corresponding to a large equipment 57 mounted between different cables 2, 2, a jig 50 is left as previously set up in the vicinity of the cables 2, 2. Next the jig 50 opens a cover in its pipe, and providing a rope 31 to be hung through a guide rope, a small gondola 36 is built and lifted. Next a rope 54 mounts its point end to a stopper hole. A large gondola 56 is built in the rope 54 and lifted, approaching the large equipment 57, and predetermined maintenance is performed. Accordingly, even for maintenance of the equipment 57 mounted between the different cables 2, 2, work can be easily performed.
