The present invention relates to a working gondola used in the case of cleaning window glass of a building such as a building.

As shown in FIGS. 31 and 32, a gondola used for cleaning window glass of a building such as a conventional building, as shown in FIGS. 31 and 32, a gondola support arm (C) protruding outward to a roof body (B) of a building (A) such as a building. To the end of this gondola support arm (C), and attach the rope (F) of the electric winch (E) installed on the gondola main body (D) which a person can work on, and operate the electric winch (E) The rope F is stretched and constructed so that the gondola main body D can be moved.

The working gondola configured as described above causes the gondola main body D to be moved by expansion and contraction of the rope F of the electric winch E, so that when the rope F is cut, it falls to the ground and a casualty accident occurs. There is this.

In order to solve this drawback, it is conceivable to attach a lifesaving rope to a worker riding on the gondola main body D, but the lifesaving rope must also be moved along with the east side of the gondola main body D. There was a fault that it was hard to do it.

In view of the above conventional drawbacks, the present invention, when the rope of the gondola body moving device for moving the gondola body up and down is cut, the auxiliary rope is automatically locked to ensure that the gondola body falls to the ground and accidents occur. It is to provide a working gondola that can be prevented, safe and comfortable to use.

The above and other objects and novel features of the invention will become more fully apparent upon reading the following detailed description in contrast with the accompanying drawings.

However, the drawings are only for explanation, and do not limit the scope of the present invention.
