A block and tackle is a simple but highly effective lifting device, thought to have been invented by Archimedes. These systems were used extensively for construction in the ancient world, and continue to be used today for various applications, especially at sea, where non-motorised 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.A mid-twentieth example of a wooden block that shows advances in the design of the marine block compared to late 19th century blocks, with hook and pin and its compliance plate meeting the marine standards of the time.Two sheave rope block; two metal sheaves in polished wooden block with a metal inner pin with a ring on top and a bucket on the bottom.

The pulley block illustrates a moment in Harcourt history. According to the reminiscences of William Sanders the granite block for the Burke and Wills monument was of such weight that, in hauling it from the quarry, the weight split the yokes and snapped the chains of the bullock team employed in the task. "So Mr Blight got ropes and tackle, as, as there were plenty of trees along the route, they served as anchors to attach the ropes" Thus, with pulleys such as this, Joseph Blight moved the monolith, at snail's pace, to the Harcourt railway station in 1864.The object is significant for its connection with the explorers Burke & Wills and the foundation of the granite industry on Mount AlexanderA wooden pulley block designed for two ropes. Used for lifting heavy objects. A rope slung around the pulley block fixed the device to the rafters of the shed. Ropes were threaded over the pulley and used to lift heavy weights. Use of a pulley halves the effort required to lift or move an object. Possibly of nautical origin but applied to workshop use in later years.
