    • PURPOSE:To secure the superior working performance and sufficient safety by raising and lowering the body of a gondola, etc. by a sucker plate, held on the wall surface of a building, etc. CONSTITUTION:An endless chain 8 is supported in shitable ways through a guide rail 7 forming an elliptical orbit in the elevation direction, along the side part of a gondola body 4 which is held in free elevation along the side surface 9 of a building 2 by a winch. A suction pressure generated by the operation of a vacuum pump 39 is supplied through a valve 27 onto a sucker plate 14 installed through a rod 13 onto the chain 8, and said sucker plate 14 is adsorbed onto the wall surface 9. When the body 4 is raised by the drive of the winch, each sucker plate 14 shifts together with the chain 8 along the orbit of the guide rail 7, and the sucker plate 14 on the wall surface 9 side is kept in the adsorbed state by the valve 27 which is opened and closed by the shift. Therefore, the working performance in cleaning the wall surface 9 is improved, and the high safety can be secured.

    • PURPOSE: To make the main body of a nacella, which supports an endless chain on a side part thereof, ascend and descend under a condition that it is held by a wall face of a building or the like, and improve the wall face cleanability by mounting the suckers on the points of the rods which are radially connected to the links of the endless chain through the springs in such manner that they can be expanded and contracted. CONSTITUTION: On the suckers 14 mounted on a chain 8 through the rods 13, the suction pressure in accompany with the operation of a vacuum pump 39, is supplied to the suckers 14 positioned on the wall face side of a building or the like, through the valves 27, and the suckers 14 are sucked to the wall face. When a wrench is driven, and a main body such as a nacella is made to ascend and descend under this condition, the suckers 14 are respectively moved along a track of a guide rail 7 with the chain 8, and the suckers on the wall face side are kept in the sucked condition by the valves 27 which are opened and closed by this movement. Whereby the main body can be surely held by the suckers sucked on the wall face of a building or the like, during the stop or movement of the main body.
