Electric Winch

By the term winch, we mean a mechanical device generally used for pulling in (winding up), letting out (winding out) or simply for adjusting the "tension" exercised by a rope, wire rope, cable or wire cable. Even in its simplest form, the winch consists of a spool and a hand crank attached to it. As regard to its larger forms, winches are treated to be the heart of the machines as they are diversely used as steam shovels, tow trucks, as well as elevators. The spool is also known as the 'winch drum'. Some of the winches have more elaborate designs like gear assemblies which are powered by hydraulic, electric, pneumatic, and internal combustion drives. Winches having a mechanical brake, solenoid brake or ratchet and pawl devices are widely used to prevent it from unwinding till the pawl is pulled back.
