It’s amazing what one person can move with the power of Thern. Our spur gear hand winches can lift, lower or position up to 10,000 pounds quickly and easily. You can also use a Thern worm gear hand winch for loads up to 4,000 pounds. And regardless of whether you choose a Thern spur gear or worm gear hand winch, you can depend on it to last. Thern engineers not only think about how to build a better performing winch, they also think about how to make it longer lasting by accounting for the demands and environmental conditions, like corrosion, related to your applications. Performance, price, prolonged life. It’s no wonder so many workers turn to Thern.
