The DBW-02/03 (number designation depends on overall size) is an affordable and highly configurable open-drum winch for light to medium duty oceanographic and geophysics research applications.  Its sturdy bolt-together channel frame can easily accommodate the addition of many standard AGO winch add-ons, including a levelwind, drum ratchet, sprocket-assisted manual backup drive, and more.

Unlike the DBW-5, it is not an enclosed winch, but a drum enclosure can be added to meet safety requirements.



Oceanographic applications, e.g. small side scan sonar, water sampling, towed instrument sleds, environmental and pipeline monitoring, lightweight grab samplers, small capture nets, subsea video, CTD profiling.

Borehole operation applications.
