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

Description du produit

The McKissick TU-481 Snatch Block is a heavy-duty, high-capacity snatch block engineered for extreme-duty rigging and lifting operations requiring a 60 Ton working load capacity with wire rope up to 2 inches in diameter. The 24-inch outside diameter roll forged sheave provides a generous rope bend radius that significantly reduces wire rope fatigue and extends rope service life under the high line loads associated with large-diameter wire rope applications. Roll forging delivers a sheave with a refined, dense grain structure that resists the extreme mechanical stresses and shock loads encountered in oilfield, offshore, heavy marine, and large-scale construction rigging operations.

Fitted with tapered roller bearings with seals, the TU-481 provides efficient load distribution across both radial and axial forces while the sealed bearing housing protects internal components from water, grit, and field contaminants. This bearing configuration ensures smooth, low-friction sheave rotation under sustained heavy loads, reduces wear on the wire rope at the sheave groove, and minimizes maintenance requirements in remote or offshore environments where regular servicing is not practical. The combination of a large sheave diameter and sealed tapered roller bearings makes this block particularly well suited for high-cycle, high-load applications where both rope and bearing longevity are critical.

As a snatch block, the TU-481 incorporates an openable side plate that allows wire rope to be inserted laterally without threading the rope end through the block, enabling fast and efficient rigging changes and load line redirection under field conditions. This block is designed for the most demanding applications including heavy crane rigging, offshore platform and derrick operations, pipeline and heavy civil construction, large vessel mooring and towing assists, and multi-part line systems where 2-inch wire rope and 60 Ton capacity are required. Always verify working load limits, wire rope diameter compatibility, and pin dimensions before placing the block into service.
