50QT Orbit Winch (50ST), 2-Speed w/ QuickTrim

Ronstan’s Orbit Winches™ are the new benchmark in high performance alloy winches. With a combination of fresh design thinking and proven manufacturing expertise, Orbit Winches™ weigh significantly less and offer lower line entry heights than any other winch in their class.
Remarkably easy to service, they require no tools for disassembly or maintenance.
The fully machined aluminium drums feature the same Power Ribs™ that many will recognize from Andersen Stainless Steel Winches®, well-known for their impressive line grip, smooth control, and minimal rope wear.

The unique, patented QuickTrim™ functionality is available in sizes 30QT to 50QT. QuickTrim allows sailors to easily and safely ease line tension to make minor in/out sail trim adjustments when racing or in challenging sailing conditions, without having to remove the winch handle or take the line out of the self-tailer jaws.
QuickTrim is easily engaged or disabled (for normal self-tailing function) with the simple removal or replacement of a single screw in the top of the self-tailing arm.

2-Speed Winches Features
• Sprung self-tailing jaws accept 7-14mm (1/4" - 9/16") line – depending on winch size selected
• Close-to-deck, low line entry allowed by favorable internal gear geometry
• Ball bearings carry the thrust loads, while roller bearings carry drum radial loads to minimize rotational friction
• Proven Andersen winch gearing configuration
• Distinctive Power Ribs™ on the drum ensure a controlled grip at all times, whether tensioning or easing
• Power Ribs minimize rope wear compared to common abrasive drum surface finishes
• Lightweight machined anodized aluminium drum – stronger and lighter than traditional cast aluminium drums
• Aluminium center stem is lighter in weight compared to bronze stems
• Quick Trim configuration is engaged, or disengaged, using a simple Phillips screwdriver
• No tools required for disassembly for maintenance
• 3-year Warranty on all models
• Note – Orbit 30QT and 40QT models and conversion kits are now available with an E1 Electric Motor for 12V or 24V systems; see Related Products

A Deeper Dive into QuickTrim™
The innovative QuickTrim™ self-tailer allows sailors to easily and safely ease line tension to make minor sail trim adjustments without having to remove the winch handle or take the line out of the self tailer.
Racing sailors can react and respond instantly to minor changes in wind direction or steering, providing an unmatched advantage when frequent sail trim adjustments are required. It’s also a nice convenience for cruising sailors.

On the water, using QuickTrim™ is intuitive and quickly becomes second nature. In use, winches typically rotate clockwise. With one hand on the tail of the sheet, rotating the spring-loaded top cover of the Orbit winch counter-clockwise with the other hand allows the self-tailer jaws to turn beneath your hand as the line is eased out in a controlled fashion.
When the top cover is released and allowed to spring back, the self-tailer locks again and grips the line to resume normal use. This simple, reliable feature is a real advantage when making frequent minor adjustments to sheet or halyard tension.

As delivered from the factory, Orbit Quick Trim winches operate as traditional two- or three-speed self-tailing winches.
The QuickTrim™ feature is enabled by the user simply by removing a single screw located under the self tailing arm. The only tool required is a Philips screwdriver to remove the screw. Step-by-step instructions are included in the Quick Reference Guide provided with the winch, and also in the product manual available from the Ronstan website.

Power Ribs
Inspired by the distinctive drum profile of Andersen winches, Power Ribs™ have been incorporated into the fully machined drums of Ronstan’s Orbit Winches™ to deliver the same impressive line handling with maximum grip and minimal line wear.
The exceptional grip provided by the Power Ribs™ offers a multitude of benefits: requiring fewer wraps around the drum, reducing the load held in the self tailer, and encouraging the line to slide easily upward on the drum to avoid riding turns.
The non-abrasive drum surface extends the service life of running rigging and allows for smooth and controlled easing, even under high loads.

No Tools Required for Disassembly for Maintenance
Full disassembly and reassembly can conveniently be performed without the need for any tools.
To remove the drum, pull back the spring-loaded release latch, then a slight counter-clockwise rotation will allow the self-tailing arm to be lifted from the winch. From there, the drum can be removed from the winch center stem.
When completing reassembly in the reverse order, an audible click confirms positive engagement between the self-tailing arm and bayonet notches on the center stem. These notches allow the self-tailing arm to be locked in one of eight positions at 45° rotational increments.
