Thern 2W40-M Worm Gear Hand Winch - 4600 lbs Pulling Capacity

Drill-Driveable Power for Heavy Pulling Applications

The Thern 2W40-M Worm Gear Hand Winch is a heavy-duty pulling solution rated for up to 4,600 lbs on the first layer, with the precision and control you'd expect from a high-quality worm gear system. Designed specifically for pulling applications, this model does not include a brake and is not rated for lifting—but it’s ideal for moving heavy equipment, materials, or loads horizontally or on inclines. The enclosed gearbox houses machine-cut bronze gearing that runs smoothly, resists wear, and operates quietly with less effort required.

The 2W40-M is drill-drive compatible, letting you use a portable drill (400 RPM max) for faster, more efficient operation—perfect for longer pulls or when repetitive use would be too slow by hand. Its cast aluminum housing is lightweight and corrosion resistant, and the oil bath lubrication system ensures long-term performance with minimal maintenance.
