Winch
A winch is a mechanical device used to pull in, let out, or adjust the tension of a rope, cable, or chain. It consists of a spool (or drum) operated manually or powered by electricity, hydraulics, or a combustion engine. Winches are commonly used in construction, vehicle recovery, marine applications, off-road towing, and industrial lifting. Their ability to exert controlled pulling force makes them essential in material handling and rigging operations where moving heavy objects with precision is required.
