Description

The CSW-7 is our most popular and versatile design. The CSW-7 is useful for medium cable lengths combined with large cable bending diameters or heavy weights in almost any light-duty marine application. It's a four person portable model that is capable of lifting and lowering most instrumentation payloads (500 lbs/ 227 kg typical). This winch comes as a complete package, including a range of standard features only available as options on our other winches.

The CSW-7 is directly available from several instrument manufacturers, equipped for use with their sensors. These manufacturers include: L-3 Klein (Klein 3900 and 5000 Side Scan Sonars), Marine Magnetics (Seaspy magnetometer) and CMAX Sonar (Side Scan Sonar).

Applications:

It is used to perform CTD profiling, side scan sonar, magnetometer towing, Rosette water sampling, towed instrument sleds, environmental and pipe line monitoring, lightweight grab samplers and small capture nets.

Motor Variants:

  • 1.0 HP to 5.0 HP 3-phase AC motor and outdoor rated AC Vector Drive (VFD) Controller, powered by 110 VAC, 220 VAC and 240 VAC (3-phase)
  • 1.0 HP to 2.0 HP permanent magnet motor @ 90/180 VDC (1.5 HP through 2 HP @ 180 VDC only) with regenerative drive controller powered from 110/220 VAC single phase (generator, inverter or ship's power)
