Scientific research winches are divided into direct pull winches and traction winches.
According to different purposes and cables, it can be divided into:
(1) CTD winch, retractable CTD
(2) Geological winch, a winch used to retract geological samplers, is usually a steel cable.
(3) Deep towing winch, a winch used to tow deep towing platforms, which can perform comprehensive observations such as terrain, geomagnetic, seismic, geothermal measurements, and underwater photography and sampling.
(4) Coaxial cable scientific research winch, coaxial cable refers to a cable with two concentric conductors, and the conductors and shielding layer share the same axis.
(5) Hydrological and biological winches, water collection, etc.
(6) Tension conversion winch.
(7) MVP winch, a walking type ocean multi parameter profile measurement system.
(8) Seismic cable winch, a cable with seismic detectors used in marine seismic exploration.
(9) Seismic gun cable winch.
(10) ROV winch.
