[0002] Hydrological winches are specialized equipment used for launching and retrieving hydrological instruments for hydrological observation. They mainly consist of a chassis, transmission system, support frame, and suspension device. Primarily used in surveying operations on rivers and lakes, hydrological cableway inspections, and bridge surveys, they are characterized by corrosion resistance and vibration resistance, and can be used with CTD (Conductivity, Temperature, Depth) instruments, underwater acoustic communication equipment, and other measuring tools.
