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

Description du produit

The McKissick QK-566 Western Cargo Hoisting Block is a heavy-duty wire rope block engineered for demanding cargo hoisting, marine lifting, and industrial rigging applications where high capacity and reliable performance under sustained load are essential. Rated at 10 Ton with a 16 in sheave outside diameter and compatibility with wire rope up to 1 in diameter, the QK-566 is built for large-scale lifting operations on vessels, docks, construction sites, and industrial facilities where standard-capacity blocks are insufficient. The Western cargo hoisting block configuration is widely used in marine and offshore environments for cargo handling, deck operations, and heavy rigging assemblies.

The tapered roller bearing is the defining mechanical feature of the QK-566, providing superior load-handling capability compared to bushing or needle bearing designs. Tapered roller bearings are engineered to carry both radial and axial thrust loads simultaneously, delivering consistent sheave rotation under heavy tension, reducing friction during wire rope travel, and maintaining alignment under the dynamic and eccentric loading conditions common in cargo hoisting service. This bearing type is the preferred choice for high-capacity blocks where mechanical efficiency, load distribution, and long service life under demanding conditions are required.

The QK-566 is part of McKissick's established line of wire rope blocks, recognized across the marine, offshore, construction, and industrial rigging industries for robust construction and load-rated performance. The 16 in sheave outside diameter provides an appropriate D/d ratio for 1 in wire rope, supporting wire rope service life by minimizing bending fatigue during repeated cycling. The block is suited for use in single or multiple part line rigging configurations depending on the application requirements and available rigging hardware.
