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

Product Description

Product Description: The Western QK-566 Series 10 Ton Wire Rope Hoisting Block in the 3/4 inch rope configuration is a heavy-duty rigging block engineered for demanding cargo hoisting, lifting, and rigging applications in industrial, marine, construction, and port operations. Designed to accommodate wire rope cable up to 3/4 inch in diameter, this block delivers the line capacity and structural strength required for high-load lifting operations while working with a smaller rope diameter than the 1 inch maximum cable variant, offering flexibility for operations where 3/4 inch wire rope is the specified or preferred line. The 16 inch sheave outside diameter provides an exceptionally generous rope bend radius for 3/4 inch wire rope, substantially reducing rope fatigue and extending rope service life over repeated heavy-duty lifting cycles.

The QK-566 Series is equipped with tapered roller bearings, which offer superior load-carrying capacity and reduced friction compared to plain bore or sleeve bearing designs. Tapered roller bearings are engineered to handle the combined radial and axial loads characteristic of hoisting and rigging applications, ensuring smooth and efficient sheave rotation under heavy loads and contributing to reliable power transmission through the block assembly. The combination of a 16 inch sheave and tapered roller bearing in this 3/4 inch rope configuration is particularly advantageous in high-cycle hoisting environments where rope wear is a significant operational consideration, as the large sheave-to-rope diameter ratio provides exceptional rope protection and contributes to lower long-term rope replacement costs.

With a 10 Ton working load limit, this hoisting block is well matched to heavy cargo lifting, crane rigging, block and tackle assemblies, and industrial material handling systems that demand high capacity and consistent performance with 3/4 inch wire rope. All rigging hardware connected to this block must be rated to the appropriate working load limit, and the block must be inspected before each use in accordance with applicable lifting and rigging safety standards.
