McKissick QK-566 Western Cargo Hoisting Block - Wire Rope - 3/4 in - 10 Ton

Product Description

The McKissick QK-566 Western Cargo Hoisting Block is a heavy-duty wire rope block engineered for high-capacity cargo hoisting, marine lifting, and industrial rigging applications requiring reliable performance with 3/4 in wire rope at a 10 Ton working load limit. With a 14 in sheave outside diameter, this 3/4 in variant of the QK-566 series is the smaller-sheave counterpart to the 1 in QK-566 16 in model, providing an appropriate D/d ratio for 3/4 in wire rope that supports wire rope service life and minimizes bending fatigue during repeated load cycling. The Western cargo hoisting block configuration is a proven design used across marine, offshore, and industrial environments for cargo handling, deck operations, and heavy rigging assemblies.

The tapered roller bearing provides the mechanical performance required for sustained high-capacity hoisting service with 3/4 in wire rope. Designed to carry both radial and axial thrust loads simultaneously, the tapered roller bearing ensures consistent sheave rotation under heavy tension, minimizes friction during wire rope travel, and maintains sheave alignment under the dynamic and eccentric loading conditions common in cargo hoisting applications. This bearing type is the standard choice for high-capacity wire rope blocks where load distribution, mechanical efficiency, and long service life are essential in demanding marine and industrial service environments.

The 14 in sheave QK-566 3/4 in model sits within McKissick's Western cargo hoisting block lineup alongside the E-566 3/4 in 14 in, PG-566 3/4 in 14 in, and J-566 3/4 in 16 in models at 10 Ton capacity, offering operators the QK-series block construction in a 14 in sheave platform optimized for 3/4 in wire rope. Together with the 1 in QK-566 16 in model, the QK-566 series provides a complete wire rope diameter range within the same block family for operators who specify QK-series construction across their rigging systems.
