Chrome Hydraulic Radial Self-Tailing Winches, 50ST - Two Speed

Hydraulic Radial winches let you trim any size sail with the push of a button. Winches mount vertically and operate using waterproof switches located near the winch. A locking handle inserted into an unloaded winch automatically disconnects the motor gear for manual operation. Manual Radial winches easily convert to power - they have identical hole patterns and don’t require an adapter plate. Harken hydraulic motors attach to the central driveshaft and drive through the winch transmission gears for multi-speed mechanical advantage - the low power first gear for fast trimming, the higher power second (or third) gear for fine-tuning loaded sheets. This allows use of a smaller, more efficient motor that saves weight and cost. • Available with chromed bronze winch drums • Each winch requires 2-3 windlass-style control switches (1st gear/2nd gear/3rd gear; sold separately), which can be used to control both the hydraulic pump and/or the valve to the winch - depending on the type of hydraulic power source • All hydraulic fittings are industry standard for ease of installation and service • Composite roller bearings reduce friction under load and don't require lubrication • Load-carrying gears and pins are 17-4PH stainless steel for strength and durability • Maximum hydraulic pressure is 120 bar (1740 psi); winch speed will vary with flow rate, optimal is 15 lpm (4 gpm) • Table: Height and Line Entry are height above deck; Depth is extension below deck
