Description

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.

Applications:

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

Motor Variants:

  • 0.5 HP to 1 HP permanent magnet motor @ 90/180 VDC with regenerative drive controller powered from 110/220 VAC single phase (generator, inverter or ship's power) 
  • 0.125 HP to 1 HP permanent magnet motor @ 12/24/48 VDC with PWM drive controller powered from 24 VDC batteries
