The McKissick E-566 Western Cargo Hoisting Block is a heavy-duty wire rope block designed for high-capacity cargo hoisting, marine lifting, and industrial rigging applications requiring reliable performance under sustained working loads. Rated at 10 Ton with a 14 in sheave outside diameter and compatibility with wire rope up to 3/4 in diameter, the E-566 is built for large-scale lifting operations on vessels, docks, construction sites, and industrial facilities. The Western cargo hoisting block configuration is a proven design widely used in marine and offshore environments for cargo handling, deck operations, and heavy rigging assemblies where a robust, load-rated block is required.
The tapered roller bearing provides the E-566 with superior mechanical performance compared to bushing or needle bearing alternatives. Engineered to handle both radial and axial thrust loads simultaneously, the tapered roller bearing delivers consistent and efficient sheave rotation under heavy tension, reduces friction during wire rope travel, and maintains sheave alignment under the dynamic and eccentric loading conditions typical of cargo hoisting service. This bearing type is the standard choice for high-capacity wire rope blocks where long service life, load distribution, and mechanical efficiency are priorities in demanding operational environments.
The E-566 is part of McKissick's established line of Western cargo hoisting blocks and is the 3/4 in wire rope counterpart to the 1 in QK-566 model, sharing the same 10 Ton working load limit in a slightly more compact platform suited to smaller wire rope diameters. The 14 in sheave outside diameter supports an appropriate D/d ratio for 3/4 in wire rope, helping to preserve wire rope service life by minimizing bending fatigue during repeated load cycles. The block is suited for use in single or multiple part line rigging configurations depending on application requirements and available rigging hardware.
