McKissick TU-484 Snatch Block - 1-1/2 in - 60 Ton - 18 in - Roll-Forged

Product Description

The McKissick TU-484 Snatch Block is a high-capacity, heavy-duty single-sheave block engineered for 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 an 18-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-484 series accommodates wire rope cable up to 1-1/2 inches in diameter.

The roll forged sheave construction delivers superior strength and fatigue resistance compared to cast sheave alternatives, making the TU-484 well suited for high-cycle operations and applications subject to shock loading or sustained tension. 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. The 18-inch sheave diameter provides a generous rope bend radius that minimizes wire rope fatigue and extends rope service life across repeated heavy loading cycles.

The TU-484 is designed for use with heavy wire rope winches, cranes, and rigging systems where maximum working load capacity, rope longevity, and bearing durability are all critical requirements. Its robust construction and sealed bearing system make it a dependable choice for oilfield, offshore, and heavy industrial operations where blocks are subjected to continuous use in demanding conditions with limited access to routine maintenance.
