Parted blocks consist of which two types of blocks?

Parted blocks are a rigging system that consists of two essential components: the standing block and the running block. The standing block is typically fixed in place and serves as an anchor point, while the running block moves along a line or cable to create mechanical advantage in lifting, hoisting, or lowering loads. This arrangement allows for a more efficient use of force, making it easier to lift heavier items with less input effort. The interaction between the standing block and the running block is fundamental to achieving the desired lifting effect and is a standard configuration in various rigging applications. Therefore, understanding this basic structure is crucial for anyone involved in rigging practices.
