Worm Gear Hand Winches From Thern Inc

For confident load-lifting control...


To the positive attributes of our other hand winches, our worm gear units add the special feature of reducing tendencies of units to backdrive under load because they operate with a low efficiency. These gears are also enclosed in a covered oil bath for constant lubrication and long life. Bronze and radial ball bearings produce smooth, efficient operation.
