<p>PURPOSE:To enhance the safety of cleaning work by providing a gondola body for work having a circular guide rail on the upper part and a suspending metal fitting for moving the working gondola body along the guide rail. CONSTITUTION:A gondola body 18 for work is formed of a pair of gondola support arms 1 fixed to the upper part of a building 2 and two pairs of guide rollers 32 for guiding lateral ropes 17 suspended from the gondola support arms 1. A pair of rope vertical moving devices 33 such as electric winch, winder or the like for vertically and laterally moving the working gondola body 18 in the regularly vertical state are mounted on both side surfaces of the working gondola body 18. The vertical moving devices 33 are operated so that the lateral ropes 17 are extended and contracted to vertically move the gondola body 18, and also operated so that the lengths of the lateral ropes are mutually differed to laterally move the gondola body 18. Thus, the cleaning work can be efficiently performed.</p> |
