Historical information

A block and tackle is a simple but highly effective lifting device, thought to be invented by Archimedes. These systems were used extensively for construction in the ancient world, and continue to be used today for a variety of applications, especially at sea, where non-motorized lifting systems are highly useful. A basic block and tackle includes a single fixed pulley, or block, and at least one additional pulley, linked with rope, to form a complete set. Depending on the size of the load being lifted, additional sets may be used to further distribute the weight.

Significance

The tackle block is not associated with an historical event, person or place, provenance is unable to be determined at this time and the item is believed to be of modern manufacture made after 1950.
