Block) Sheave Block/Pulley ...Pulleys were used to lift goods to and from boats and at other sites at the lightstation where hauling was undertaken. Historical images and text panels in the Wilsons Promontory Museum attest to the detailed logistics that needed to be exercised in lifting and transporting goods once they had arrived by boat at the Eastern Landing. Cranes and a flying fox were employed in the nineteenth century and updated versions of this equipment served well into the twentieth century. The first cranes to be employed at the site were built just after December 1857, when tenders were called to construct two cranes prior to the commencement of building the lightstation.The first boat landing at the promontory was built on the west side of the lighthouse, which the architect, Charles Maplestone sketched in June 1859, the same month that he announced the completion of the lighthouse. His drawing shows one of the cranes as a large structure built for heavy duty lifting. Soon the east landing became the preferred place for delivering stores, but as late as 1993 a crane, timber structures and disused heavy iron machinery remained at the old site.Large rusted iron pulley, large loop at one end and smaller loop at the other.

Equipment - Block, Late 19th to early 20th century
... 2 sheave wood block... mechanical advantage. In general, the more sheaves in the blocks...A two sheave wood sailing block with metal hook and becket... the sheaves, and maybe through one or more matching blocks at the far ...A sailing block is single or multiple pulleys with one or more sheaves that are enclosed in an assembly between cheeks or chocks. In use, a block is fixed to the end of a line, to a spar, or a surface. A rope line is reeved through the sheaves, and maybe through one or more matching blocks at the far end, to make up what's known as a tackle. The purchase of a tackle refers to its mechanical advantage. In general, the more sheaves in the blocks that make up a tackle, the higher its mechanical advantage. The matter is slightly complicated by the fact that every tackle has a working end where the final run of rope leaves the last sheave. More mechanical advantage can be obtained if this end is attached to the moving load rather than the fixed end of the tackle. Various types of blocks are used in sailing. Some blocks are used to increase mechanical advantage and others are used simply to change the direction of a line. A ratchet block turns freely when a line is pulled in one direction but does not turn in the other direction, although the line may slip past the sheave. This kind of block makes a loaded line easier to hold by hand and is sometimes used on smaller boats for lines like main and jib sheets that are frequently adjusted. A single, large, sail-powered warship in the mid-19th century required more than 1,400 blocks of various kinds and sizes.A historic item from an old sailing vessel from the late 19th to early 20th century, unfortunately.

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.

Wooden closed spelter double rope block with two pully's between sheaves, block has metal frame around outside of the sheaves and 4 metal pins, 2 each side of the frame at top and 2 at bottom, joining the sheaves together. The shaft between the sheaves is also wooden. Remnants of orange and black paint on outside of block. Shafts are chipped, wood has borer holes.
