McKissick TU-481 Snatch Block - 1-1/2 in - 60 Ton - 18 in - Roll-Forged

Product Description

The McKissick TU-481 Snatch Block is a heavy-duty, high-capacity single-sheave block engineered for the most demanding wire rope rigging applications in industrial, oilfield, construction, and marine 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, delivering exceptional load capacity, precise rope alignment, and long service life under sustained heavy loads. The TU-481 series is designed to accommodate wire rope cable up to 1-1/2 inches in diameter.

The roll forged sheave construction provides superior strength and fatigue resistance compared to cast sheaves, making it well suited for high-cycle operations and shock-load conditions common in heavy rigging and oilfield work. The tapered roller bearing with seal offers high radial and axial load capacity while the integrated seal protects the bearing from contamination by dirt, water, and debris, reducing maintenance requirements and extending operational life in harsh field conditions. The 18-inch sheave diameter provides a generous rope bend radius that minimizes wire rope fatigue and extends rope service life across repeated loading cycles.

The TU-481 snatch block is designed for use with wire rope winches, cranes, and rigging systems where high working load limits and reliable performance are critical. Its robust construction makes it a preferred choice for oilfield, offshore, heavy construction, and industrial load-handling operations requiring a dependable high-capacity block with low maintenance demands.
