<p>PURPOSE:To simply correct inclination of a hanging type working machine which is hung by two wire ropes and elevatably moved. CONSTITUTION:A mechanism constituted of a power cylinder 11, a reduction gear 18, a servo motor 19, a rotary encoder 20, and the like, is interposed in one of two wire ropes 4 with which an automatic window cleaning unit 1 is hung. Inclination of the unit 1 is obtained as the detected signal from an inclination sensor attached to the automatic window cleaning unit 1, the length of the wire rope 4 is controlled by a control device 32 based on the signal, and hence the inclination is corrected. Hereby, the inclination can be always corrected regardless of the position of the automatic window cleaning unit 1, and cleaning of the window glass can be performed safely and perfectly without leaving not yet wiped parts.</p> |
