Worm Gear Hand Winches Built for Controlled Manual Lifting

Thern Worm Gear Hand Winches are precision-engineered manual winches designed for lifting, pulling, and positioning loads with capacities up to 4,600 lb, depending on the model. They feature machine-cut worm gears and many operate in an enclosed oil bath, ensuring smooth operation and long service life. Models with automatic mechanical brakes provide secure load-holding while lifting or pulling. The cast aluminum housing offers corrosion resistance, making them suitable for outdoor and harsh environments, while bronze bearings reduce friction and wear. Large-diameter drums minimize wire rope wear, extending service life, and adjustable handles allow users to balance force and speed. Multiple mounting options—floor, wall, or ceiling—ensure flexible installation. These winches combine durability, precision, and safety, and are widely used in industrial, marine, and construction applications.
