McKissick TU-484 Snatch Block - 1-1/2 in - 30 Ton - 20 in - Roller Bearing

Product Description

The McKissick TU-484 Snatch Block is a heavy-duty single-sheave block engineered for high-capacity 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 superior sheave durability under sustained heavy loads. The TU-484 series in this configuration 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 in demanding field environments. The roller bearing sheave minimizes friction and heat buildup during operation, supporting reliable performance in high-cycle and sustained-load environments common to heavy industrial and oilfield rigging. The snatch block configuration features a side-opening cheek plate that allows the wire rope to be inserted without threading the rope end through the block, reducing rigging time and improving setup efficiency in the field.

The 20-inch sheave diameter provides a generous rope bend radius that significantly reduces wire rope fatigue and extends rope service life across repeated heavy loading cycles, an important advantage in high-capacity rigging applications where larger-diameter wire rope is subjected to sustained tension and repeated bending. The TU-484 in this 30-ton, 1-1/2-inch rope capacity configuration offers a balance of high working load capacity, roll forged sheave durability, and roller bearing performance suited for demanding oilfield, offshore, marine, logging, and heavy construction applications.
