Product Introduction Double Tethered High-altitude Cleaning System SF – 90X – 100M is mainly composed of a tethered power supply system, an integrated water pump system (exclusive), and a heavy – load unmanned aerial vehicle. It is mainly designed for the curtain wall cleaning and spraying market. It aims to replace “spidermen” and improve the efficiency and safety of the maintenance of the exterior surfaces of urban high – rise buildings, power plants, and chemical plants. The innovative tethered design has significantly enhanced the traditional water – based tethered endurance capacity, effectively solving the problem of achieving unlimited endurance for the last 100 meters. Airfly Tethered can provide solutions for the tethered power supply systems of heavy – load water – based tethered cleaning platforms. The height ranges from 50m to 300m, and the power ranges from 18kw to 60kw, which can meet the needs of different customers. Application Scenarios Application scenarios in the curtain wall cleaning market, as well as in special spraying industries such asscientific research institutions, high voltage power tower insulators, boiler plants, and chemical plants.
