The CSW-9 is an enlarged version of the CSW-6 that is useful for short cable lengths combined with large cable bending diameters or heavy weights in almost any light-duty marine application. It's a two to four person portable winch designed for lifting and lowering small to moderate instrumentation payloads and towed body operations. It has proven to be a versatile winch which may be used in almost any application. This model is typically used for shallow-water operations with heavier loads or large diameter cable.This winch comes as a complete package, including a range of standard features only available as options on our other winches. It is capable of lifting and lowering many instrumentation payloads (300 lbs typical, please, contact us for more information on load pull and line speed, values can vary significantly)
