45QT Orbit Winch, 3-Speed, QuickTrim
Lightweight aluminium winch with QuickTrim™ self-tailer, 3 speeds, and Power Ribs™ for controlled grip on the line at all times.
FEATURES
- Sprung self-tailing jaws to accept 8 – 14mm line.

- Ball bearings carry the thrust loads, roller bearings carry the radial loads of the drum to minimise rotational friction.
- Proven gearing configuration.
- Power Rib™ ensures a controlled grip on the line at all times, whether trimming or easing. Minimal rope wear compared to more abrasive drum surface finishes.
- 45QT and 50QT available as three-speed models.
- Machined aluminium drum – stronger and lighter than traditional cast aluminium drums.
- Lightweight aluminium centre stem provides significant weight savings over traditional bronze stems.
- Low line entry due to gearing configuration geometry.
