1. The turning speed is not more than 15m/min; the variable speed is not more than 20m/min; the lifting speed is not more than 20m/min; the running speed is not more than 15m/min.
2. The fixed-type guardrail should be installed around the gondola of the high-rise window cleaning machine. The guardrail should be equipped with a web. The guardrail height-degree should not be lower than 0.8m on the side of the building, and the other part should be no less than 1.1m. The guardrail should be able to withstand the horizontal concentrated load of 1000N. A baffle with a height of not less than 150 mm shall be provided around the lower part of the guardrail, and the gap between the baffle and the bottom plate shall be no more than 5 mm.
3. When working under the rated load, the noise of the operator's ear should not exceed 85dB (A), and the noise outside the machine should be no more than 80dB (A).
4. The test of the high-rise window cleaning machine is based on the whole machine's work-cycle number of 3000 times. The work-circle-loop consists of the lifting of the gondola, the boom amplitude, the rotation, and the trolley walking.
