A block and tackle or only tackle 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.
Additionally, what is a real world example of a block and tackle? An example of a block and tackle is a method of hoisting up heavy blocks of metal using cables and pulleys. A system of two or more pulleys (the tackles) each enclosed by a housing (the block) with a rope or cable threaded between them, usually used to lift or pull heavy loads.
Similarly, what is the advantage of using the block and tackle? A block and tackle rigging holds an advantage when the rope is pulled in the same direction that the load will be moved. It is rigged to disadvantage when it is being pulled in the direction opposite of where the load is to be moved (pulling down on a load to be lifted, for example).
Likewise, what are pulley blocks used for? Pulley blocks give direction to the rope while loaded; they are able to increase the line pull or lifting capacity of a hoist or winch by multiplying the number of lines.
