A hand operated winch is a winch that can lift heavy objects by manually winding a wire attached to the object. The greatest advantage of a hand operated winch is that it can be installed anywhere, whereas an electric winch is limited by the availability of electric power.
In order to pursue the advantage of being able to be set up anywhere, there are also products with improved durability, such as salt resistance and rust resistance. There are also special large hand operated winch that can lift objects weighing up to 10 tons.
Hand operated winches are used at many work sites and facilities.
For example, ball nets are used on baseball fields, golf courses, and driving ranges, etc. Stretching these nets on poles by hand alone requires a great deal of labor. However, the use of hand operated winches can reduce this labor to a fraction of its original cost.
Hand operated winches are also used to raise and lower ship boarding ramps, adjust the height of work steps, adjust the height of piers, and in other situations where it is necessary to raise or lower heavy objects and secure them safely in a certain position.
Hand operated winches consist of three main components: a frame that supports the entire winch, a drum that winds the wire, and a handle that rotates the drum.
The shaft of the handle has a pinion gear, which is connected to a drum gear on the outer circumference of the drum. When the handle is turned, the drum gear turns via the pinion gear, and the wire is wound up. Since the drum gear is much larger than the pinion gear, a larger torque can be generated, but the amount of torque required to turn the handle is greater. The reduction ratio (ratio of the number of teeth on the pinion gear to the drum gear) of small hand operated winches are about 1/4, but there are manual winches that can lift a 10-ton heavy object with a reduction ratio of about 1/300. In other words, it takes 300 rotations of the handle to make one rotation of the drum. Hand operated winches are usually equipped with an automatic brake, so that the heavy object being lifted will not fall if something should happen to it.
