Description
A block sheave is a key component of a pulley system used to guide and change the direction of rope or wire under load. Typically housed within a block, the sheave is the rotating wheel that allows smooth and efficient movement, reducing friction during lifting or rigging operations. Commonly made from materials like nylon, bronze, or stainless steel, marine sheaves are built to withstand the harsh marine environment. They are essential in sailboat rigging, hoisting gear, and other onboard mechanical systems requiring controlled line handling.
