Product Introduction
The SF-90X-100M dual-tethered high-altitude cleaning system consists of a tethered power supply system, an integrated water pump system (exclusive), and a high-load drone. It is primarily designed for the curtain wall cleaning and spraying market, replacing the traditional "Spider-Man" method and improving the efficiency and safety of facade maintenance on urban high-rise buildings, power plants, and chemical plants. The innovative tethering design significantly improves the endurance of traditional water-based systems, effectively solving the problem of unlimited endurance in the last 100 meters. Weize Tethering provides tethered power supply system solutions for high-load water-based tethered cleaning platforms, ranging in height from 50 to 300 meters and with power outputs from 18 kW to 60 kW, to meet diverse customer needs.
Application Scenarios
The dual-tethered high-altitude cleaning system is an innovative solution designed specifically for the curtain wall cleaning and spraying market. It aims to replace traditional "Spider-Man" methods and significantly improve the efficiency and safety of facade maintenance on urban high-rise buildings, power plants, chemical plants, and other structures. This system significantly improves the endurance of water-tethered drones through tethering technology, completely resolving the pain point of traditional drones, which struggle with short power supply times and are unable to meet large-scale operations. It effectively achieves unlimited endurance for the last 100 meters, laying a solid foundation for widespread adoption.
Safety and efficiency are the core advantages of this system. The company provides matching electric tethering systems for all water-tethered platforms, meeting varying altitude and power requirements. The system's altitude coverage ranges from 50 to 300 meters, and its power output ranges from 18 kW to 60 kW, flexibly adapting to the diverse needs of different clients. Whether for routine cleaning of high-rise buildings or specialized spraying tasks at industrial facilities, our tethered water spraying system provides a stable and reliable solution, helping customers achieve efficient and safe operations.
