Martin Sprocket 3V Series Hi-Cap Wedge Stock QD sheaves are used in belt-driven systems for efficient power transmission. These sheaves offer a one-piece solid construction for durability, a 3 groove system for accommodating three belts simultaneously and QD bushings to allow easy installation and removal. They are made of Class 30 grey iron, offering a maximum textile strength of 30000 psi for use in heavy applications. These units have a smooth surface finish to minimise belt slippage and are ideal for use with 3V cross-section belts to ensure reliable power transfer.
Blocks and Sheaves are designed to lift heavy loads when used with heavy-duty wire rope or aircraft cable. Available options include forged block fittings with zinc finish and are riveted to all-steel sheaves that can resist weather damage and offer prolonged durability. Choose from a wide variety of types, sizes, load capacity or dimensions.
