Trojan 3:1 & 1:1 Manual Trailer Winch TR85700

Meet the Trojan TR85700, a dual-gear manual trailer winch designed for boaters who value control, durability, and versatility when loading and unloading on trailers. Built for saltwater environments and exposed conditions, this winch delivers reliable performance across a range of boat sizes and ramp grades.

  • Dual gearing: 3:1 winding option for heavier loads and 1:1 for straightforward, direct winching—switchable to match boat weight, ramp incline, and conditions.
  • Max pull: 500 kg capacity, covering most small to mid-size powerboats and sailing craft commonly trailer-launched.
  • Marine-grade construction: galvanised frame with stainless steel components for corrosion resistance and long service life in marine settings.
  • Rope or wire configuration: configurable with rope or wire; wire not included, rope options sold separately to suit your setup.
  • Parts and service support: extensive spare parts and dedicated service kits (e.g., T800027, T800028, T800029) to refresh pawl handles, springs, gears, and brushes, minimizing downtime.
  • Compatibility and accessories: designed to pair with Trojan’s family of marine winches and compatible rope lengths (e.g., 6 m of 4 mm rope) from related accessories, ensuring proven performance with your kit.

Benefits: With the TR85700, boat loading becomes smoother and more controllable, reducing strain on you during ramp launches and recoveries. The dual-gear system gives you the right amount of power for heavier boats or the simplicity of a direct 1:1 pull for quick loads. The galvanised, marine-grade build stands up to spray, rain, and outdoor storage, while Trojan’s service network makes maintenance straightforward so you can rely on your winch season after season. Whether you’re a boat owner, club, or rental fleet, this winch adapts to varying boat sizes and ramp grades, delivering consistent performance and safer operation during every trailered launch and retrieval.
