McKissick TU-483 Snatch Block - 1-1/2 in - 60 Ton - 24 in - Roll-Forged

Product Description

The McKissick TU-483 Snatch Block in the 24-inch sheave configuration is a heavy-duty, high-capacity snatch block engineered for the most demanding rigging and lifting operations requiring a 60 Ton working load capacity. Designed to accommodate wire rope up to 1-1/2 inches in diameter, this block features a 24-inch outside diameter roll forged sheave that provides an extended rope bend radius, reducing wire rope fatigue and extending rope service life in high-cycle applications. Roll forging produces a sheave with a refined, dense grain structure that delivers superior toughness and resistance to the extreme mechanical stresses encountered in oilfield, offshore, and heavy industrial rigging environments.

The TU-483 is equipped with tapered roller bearings with seals, offering efficient distribution of both radial and axial loads while the sealed bearing housing prevents ingress of water, grit, and contaminants. This bearing arrangement ensures smooth, low-friction sheave rotation under sustained heavy loads, minimizes rope wear at the sheave groove, and reduces maintenance frequency in remote or offshore locations where servicing opportunities are limited. The larger 24-inch sheave diameter further contributes to reduced fleet angle stress and improved rope-to-sheave contact geometry under load.

As a snatch block, the TU-483 features an openable side plate for lateral wire rope insertion without threading the rope end through the block, enabling rapid rigging changes and efficient load line redirection in the field. The 24-inch sheave variant is particularly well suited for applications involving longer rope runs, higher line speeds, or situations where minimizing rope wear is a priority, including crane rigging, heavy offshore lifts, pipeline construction, and multi-part line systems. Always confirm working load limits, wire rope diameter compatibility, and pin dimensions before placing the block into service.
