A winch is a mechanical device that is used to pull in (wind up) or let out (wind out) or otherwise adjust the "tension" of a rope or wire rope (also called "cable" or "wire cable"). In its simplest form it consists of a spool and attached hand crank. In larger forms, winches stand at the heart of machines as diverse as tow trucks, steam shovels and elevators. The spool can also be called the winch drum. More elaborate designs have gear assemblies and can be powered by electric, hydraulic, pneumatic or internal combustion drives. Some may include a solenoid brake and/or a mechanical brake or ratchet and pawl device that prevents it from unwinding unless the pawl is retracted.Breif Specification:

Applications Of Winches:
Anchor winch of the polar research vessel Polarstern.
The rope is usually stored on the winch, but a similar machine that does not store the rope is called a capstan. When trimming a line on a sailboat, the crew member turns the winch handle with one hand, while tailing (pulling on the loose tail end) with the other to maintain tension on the turns. Some winches have a "stripper" or cleat to maintain tension. These are known as "self-tailing" winches.[1]
Winches are frequently used as elements of backstage mechanics to move scenery in large theatrical productions. They are often embedded in the stage floor and used to move large set pieces on and off.
Winches have recently been fabricated specifically for water and snow sports (e.g. wakeboarding, wakeskating, snowboarding, etc.). This new generation of winches is designed to pull riders swiftly across a body of water or snow, simulating a riding experience that is normally supplied by a boat, wave runner, or snow mobile.
Types of winches
Lever Winch
Lever winches also commonly known as Tirfors(™) or Griphoists(™), are winches that use self-gripping jaws instead of spools to move rope or wire through the winch. Powered by moving a handle back and forth, they allow one person to move objects several tons in weight
Wakeskate winch
Wakeskate winching is a growing hobby for many watersports enthusiasts. The winch consists of an engine, spool, rope, handle, frame, and some sort of simple transmission. The person being towed walks (or swims) away from the winch and pulls out all of the rope. When the winch is engaged, it pulls the boarder usually between 15 to 25 miles per hour (24 to 40 km/h). The winch may be mounted on the trailer hitch of a vehicle, set into the ground by stakes, or tied to a tree. These winches have been modified for use by skiers and snowboarders in cities.
Glider winch
Gliders are often launched using a winch mounted on a trailer or heavy vehicle. This method is widely used at European gliding clubs, as a cheaper alternative to aerotowing. The engine is usually a large Petrol, LPG or diesel, though hydraulic fluid engines and electrical motors are also used. The winch pulls in a 1,000 to 1,600-metre (3,000 to 5,500 ft) cable, made of high-tensile steel wire or a synthetic fibre, attached to the glider. The cable is released at a height of about 400 to 700 metres (1,300 to 2,200 ft) after a short, steep climb.
Air Winch
An air winch, sometimes known as an air hoist or air tugger, is an air-powered version of a winch. It is commonly used for the lifting and the suspension of materials. In the oil and gas, construction, and maritime industries, air winches are frequently preferred to electric, diesel, and hydraulic winches because of their durability, versatility, and safety.
