McKissick TU-482 Snatch Block - 1-1/4 in - 30 Ton - 20 in - Roller Bearing

Product Description

The McKissick TU-482 Snatch Block is a heavy-duty, high-capacity single-sheave block engineered for demanding wire rope rigging applications in oilfield, offshore, marine, heavy construction, and industrial environments. Rated for a 30-ton working load limit, this block is built around a 20-inch outside diameter roll forged sheave supported by a roller bearing, delivering smooth, low-friction rope travel and reliable load handling under sustained heavy loads. The TU-482 series in this configuration accommodates wire rope cable up to 1-1/4 inches in diameter.

The roll forged sheave construction provides superior strength and fatigue resistance compared to cast sheave alternatives, making the TU-482 well suited for high-cycle operations and applications subject to shock loading or sustained tension. The roller bearing sheave minimizes friction and heat buildup during operation, supporting dependable performance across repeated heavy loading cycles in demanding field conditions. The 20-inch sheave diameter provides a generous rope bend radius that significantly reduces wire rope fatigue and extends rope service life compared to smaller sheave configurations, making this block particularly well suited for high-capacity rigging operations where both load capacity and rope longevity are priorities.

The TU-482 is designed for use with heavy wire rope winches, cranes, and rigging systems where high working load capacity, roll forged sheave durability, and reliable bearing performance are all critical requirements. Its robust construction makes it a dependable choice for oilfield, offshore, marine, and heavy industrial operations where blocks must perform consistently under continuous use in harsh and demanding field environments.
