Ronstan RA6402 40QT Orbit Winch with QuickTrim Self-Tailer

The Ronstan 40QT Orbit Winch represents a breakthrough in high-performance marine winch design, combining lightweight construction with exceptional functionality. Engineered with machined aluminum components and featuring the patented QuickTrim self-tailer system, this two-speed winch delivers a powerful 39.5:1 gear ratio while weighing significantly less than comparable winches in its class.

Key Features:

• Lightweight machined aluminum drum with distinctive Power Ribs for controlled grip during tensioning or easing
• Patented QuickTrim self-tailer allows safe line easing without removing the winch handle or line from the self-tailer
• Tool-free disassembly and maintenance with spring-loaded release latch and bayonet mounting system
• Two-speed operation with gear ratios of 1.4:1 (first speed) and 6.8:1 (second speed)
• Self-tailing jaws accommodate line sizes from 7-12mm with glass-filled nylon construction
• Low line entry height of 57mm for improved efficiency and reduced friction
• Self-tailing arm rotates to eight positions at 45-degree increments for optimal positioning

Construction and Materials:

• Hard anodized aluminum drum, center stem, and self-tailing arm for corrosion resistance
• Grade 316 stainless steel shaft and pawls for long-term durability
• Grade 2205 stainless steel axle pins for superior strength
• Aluminum bronze gears for smooth, reliable operation
• Self-lubricating acetal bearings for low-maintenance performance

Technical Specifications:

• Maximum pulling load: 850kg (1,874 lbs)
• Power ratios: 8.3:1 (first speed), 39.5:1 (second speed)
• Drum diameter: 86mm (3.39 inches)
• Base diameter: 151mm (5.94 inches)
• Overall height: 166mm (6.54 inches)
• Weight: 3.1kg (6.83 lbs)

The QuickTrim feature allows sailors to ease the line with a small counter-clockwise rotation of the self-tailing cover, which then acts as a sheave for controlled line release. The Power Ribs drum surface provides exceptional grip with fewer wraps required, reducing load on the self-tailer while preventing riding turns and extending line service life.
