Function

General function: Used to increase the mechanical power applied to ropes, or to lead them to convenient positions for handling. Specific: Used extensively on sailing ships for raising and lowering sails and also on steam and motor vessels.

Technical

A block and tackle is a system of two or more pulleys with a rope or cable threaded between them, usually used to lift or pull heavy loads. The pulleys are assembled together to form blocks so that one is fixed and one moves with the load. The rope is threaded, or reeved, through the pulleys to provide mechanical advantage that amplifies that force.
