McKissick 431 Super Champion Snatch Block - 1-1/8 in - 20 Ton - 12 in - Bronze Bushing

Description du produit

The McKissick Series 431 Super Champion Snatch Block is a heavy-duty single-sheave block built for high-capacity rigging, pulling, and load-redirection operations in the most demanding industrial environments. Rated to a 20-ton working load capacity and designed to accommodate wire rope up to 1-1/8 inch in diameter, the Series 431 is engineered for applications where maximum strength and durability are required. The 12-inch sheave outside diameter provides a generous rope bend radius, helping to preserve wire rope integrity under sustained heavy loads in oilfield, construction, marine, and offshore applications.

The Series 431 Super Champion features a bronze bushing bearing, a proven bearing type in heavy industrial block applications valued for its durability, load-bearing capacity, and resistance to contamination in harsh field conditions. The snatch block design incorporates a side-opening cheek plate, allowing the block to be rigged onto or removed from a wire rope at any point without threading the line — an important operational advantage in field environments where efficiency and accessibility matter.

McKissick's Super Champion designation reflects an elevated level of construction within their block lineup, intended for sustained use under high working loads. These blocks are commonly deployed with heavy winches, cranes, and pulling systems where wire rope direction changes or increased mechanical advantage are required. All attachment hardware including shackles and hooks should be rated to match or exceed the block's working load limit to maintain a safe and compliant rigging assembly.
