Description

  The present invention relates to a gondola device for corner work, and is a gondola device that works from a work cage via a rope such as a wire rope hanging from the upper part of a structure such as a building, and the corner portion where the side of the structure forms an angle Even so, the work cage can be operated by changing the angle of the work cage with respect to both sides centered on the corner.

  Conventionally, it is hung with a rope such as a wire rope to safely and efficiently perform high-level work such as building and repairing side surfaces such as walls of structures such as buildings, ships, power plants, tanks, chimneys, and bridges. A gondola device equipped with a work cage on which a lowered operator is boarded or a gondola device with a suspended work cage equipped with an automatic window cleaning device is often used. A wide range of work can be performed by moving the work cage in combination with a mechanism that can be moved up and down, and if necessary, can be moved up and down as well as up and down as needed (for example, patents) References 1 and 2).

  When working with a gondola apparatus having such a working cage, for example, as shown in FIG. 7, the structure S has a corner portion C in which the side surfaces S1 and S2 form an angle, and the inside of the structure S It is also necessary to work on a portion that becomes the protruding corner C1 such as 90 degrees or a portion that becomes the entering corner C2 such that the angle inside the structure S is 270 degrees.

  When working with the gondola device A to such a corner portion C that becomes the exit corner C1 or the entrance corner C2, after working on one side surface S1, (S2) of the corner portion C, the other side After the two side cages 2 and 2 are assembled with the gondola device A according to, for example, the angle of the corner portion C to be the exit corner C1, There is one that suspends two working cages 2 and 2 that are assembled at an angle to perform work.
