2. Winch - Wikipedia

   en.wikipedia.org/wiki/Winch

   The winch may be mounted to a vehicle, set into the ground by stakes, or tied to a tree. The cable may also be run through pulleys mounted offshore so that it pulls the person away from where the winch is located, and multiple pulleys may be used to multiply the force applied by a small but high revving motor instead of using a transmission.

3. Mechanical advantage device - Wikipedia

   en.wikipedia.org/wiki/Mechanical_advantage_device

   Examples of rope and pulley systems illustrating mechanical advantage. Consider lifting a weight with rope and pulleys. A rope looped through a pulley attached to a fixed spot, e.g. a barn roof rafter, and attached to the weight is called a single pulley. It has a mechanical advantage (MA) = 1 (assuming frictionless bearings in the pulley ...

4. Fairlead - Wikipedia

   en.wikipedia.org/wiki/Fairlead

   When attached to a track to make its position adjustable, a fairlead leading a jibsheet to a winch can be moved fore, aft and sometimes side to side to allow a sailor to tune sail trim to wind conditions. [3] In this duty, angle of the fairlead determines the depth of the sail, height of the clew, leach tension and other sail trim variables. [4]

5. Rigger (industry) - Wikipedia

   en.wikipedia.org/wiki/Rigger_(industry)

   Riggers attach loads of equipment to cranes or structures using shackles, cables, chains, clamps or straps, employing pulleys, winches, lifts or chain hoists (aka chain motors). Quick load calculations are necessary for each load and engineering principles are always in play.

   Pulley in oil derrick A hoist using the compound pulley system yielding an advantage of 4. The single fixed pulley is installed on the hoist. The two movable pulleys (joined) are attached to the hook. One end of the rope is attached to the crane frame, another to the winch.

7. Block and tackle - Wikipedia

   en.wikipedia.org/wiki/Block_and_tackle

   A block and tackle [1] [2] or only tackle [3] is a system of two or more pulleys with a rope or cable threaded between them, usually used to lift heavy loads.. The pulleys are assembled to form blocks and then blocks are paired so that one is fixed and one moves with the load.
