The LTJ-1 is an extremely basic winch intended to fill various special purpose roles. Designed around a simple, lightweight and sturdy framework with great variability in the motor and drum configurations, the LTJ-1 has been adapted for roles mounted on masts, as a rope recovery capstan winch and as an ultra-low-voltage remote buoy winch.

The LTJ-1 uses a direct drive from the gearbox which, combined with other design features, results in a near-zero-maintenance design ideal for remote applications. Its small size and reduced part count means it is easily shipped by air as luggage when placed inside an appropriate hardshell case.


Instument buoy anchor recovery, inflatable tender mounted mini-CTD profiling and on a solar-powered water quality profiling buoy.
