A double pulley system also known as a block and tackle consists of the pulleys or blocks and the tackle the ropes riven through the blocks.
A rope and pulley system that is a block and tackle is characterised by the use of a single continuous rope to transmit a tension force around one or more pulleys to lift or move a load the rope may be a light line or a strong cable.
While a single pulley allows you to move a load with half the force required a system of pulleys increases the mechanical advantage by the number of pulleys and the lengths of rope that support the load.
