McKissick TU-481 Snatch Block - 2-1/4 in - 60 Ton - 24 in - Roll-Forged

Description du produit

The McKissick TU-481 Snatch Block is a high-capacity, heavy-duty single-sheave block engineered for the most demanding wire rope rigging applications in oilfield, offshore, marine, heavy construction, and industrial environments. Rated for a 60-ton working load limit, this block is built around a 24-inch outside diameter roll forged sheave supported by a tapered roller bearing with seal, providing exceptional load capacity, precise rope alignment, and long-term reliability under sustained heavy loads. The TU-481 series in this configuration accommodates wire rope cable up to 2-1/4 inches in diameter, representing the largest rope capacity variant in the TU-481 series.

The roll forged sheave construction delivers superior strength and fatigue resistance compared to cast sheave alternatives, making the TU-481 well suited for high-cycle operations and applications subject to shock loading or sustained tension in demanding field environments. The tapered roller bearing with seal provides high radial and axial load capacity while the integrated seal protects internal bearing components from contamination by dirt, water, mud, and debris, reducing maintenance intervals and extending operational life in harsh and remote field environments where routine servicing may be limited. The 24-inch sheave diameter provides a suitable rope bend radius for the large 2-1/4-inch wire rope diameter accommodated by this configuration, supporting rope longevity during high-capacity, high-cycle rigging operations.

The TU-481 in this 2-1/4-inch rope capacity, 60-ton configuration is designed for the heaviest wire rope rigging applications where maximum rope diameter capacity, roll forged sheave durability, and sealed bearing performance are all critical requirements. This block is well suited for use with the heaviest wire rope winches, cranes, and rigging systems in oilfield, offshore, marine, and heavy industrial operations where blocks are subjected to continuous use under maximum loads in demanding conditions with limited access to routine maintenance.
