If you need a heavy-duty, industrial-grade winch, Ramsey's DC-300 Ram Lok winches could be what you're after. Instead of the planetary-type gear sets used in most automotive winches, which give you lots of line speed, these Ramsey units use a rugged worm-drive setup, which translates into pure brute strength. With their 470:1 reduction ratio, they can generate an impressive 9,000 lbs. of rated pulling power, while drawing just 65 amps under no load, and 310 at maximum load. They feature both free-spooling and power-in/power-out, and all moving parts are fully enclosed for maximum protection and longer wear.
