The Fully Hydraulic Winch

Make the most of your power.

Patterson’s Fully Hydraulic Winch gives you all the power of an electric winch without the risk of explosion. The anti-spark design uses your boat’s existing hydraulics to do the heavy lifting—no more worries about injuries or accidents from inappropriate use of electrics. The disc brake is motor-mounted, fully enclosed, spring-applied, and hydraulically released, and using this winch couldn’t be easier: simply vary the input flow to vary the take-up speed.

The performance you need

The Fully Hydraulic Winch is available in capacities from 20 to 90 tons. Corrosion protection varies: choose a galvanized design, or opt for the hot-dipped galvanized saltwater package, which includes stainless steel shafts, nuts, and bolts and anti-seize on all threads or fasteners. Heavy-duty roller chain and sprockets, strong roller bearings, and high-strength phosphor bronze bearings make this winch suitable for use in challenging situations.

Designed right.

This winch features a high-efficiency planetary gear head and a bolted keeper plate for fast and easy shaft removal. Rope and gear guards protect your wire rope and enclose the gearing, and the manual locking dog allows for emergency use. Brake, shuttle valves, and controls are also available.
