<p>PURPOSE:To facilitate the cleaning work by fixing a pair of gondola supporting arms on the upper part of a building, and providing lateral ropes suspended from the gondola supporting arms and the gondola body for work. CONSTITUTION:The gondola for work is formed of a pair of gondola support arms 1 fixed to the top part of the building 2, lateral ropes 17 suspended from the gondola supporting arms 1, and a working gondola body 18. The working gondola body 18 has a gondola frame 23 allowing a worker to get on the gondola body 18 and a movable arm on which a pair of guide rollers 27 for guiding the lateral ropes 17 in cross. When the working gondola body 18 is laterally moved, a pair of vertical moving devices are operated so that the upper lengths of the lateral ropes 17 are mutually differed to laterally move the gondola body 18. Thus, a cleaning work can be safely done.</p> |
