Winches

Winches

A winch is a mechanical device made of ropes, cables, and chains that wind around a horizontal rotating drum. Their purpose is to lift and pull heavy items. When a power source is unavailable or not practical, manual winches are powered by hand cranks. A manual winch requires more effort to pull, move, or tow loads. An electric winch requires less effort. Due to their precise load control capabilities, air winches are widely used in construction and maintenance.
