The McKissick Series 430 Super Champion Snatch Block is a heavy-duty single-sheave block built for the highest-demand rigging, pulling, and load-redirection applications in industrial and oilfield environments. Rated to a 30-ton working load capacity and designed to accommodate wire rope up to 1-1/4 inch in diameter, the Series 430 represents the upper tier of McKissick's Super Champion snatch block lineup, engineered for sustained performance under extreme loads. The large 20-inch sheave outside diameter provides a generous rope bend radius that helps protect wire rope integrity and reduces fatigue during high-cycle, heavy-load operations in construction, oilfield, marine, and offshore applications.
This Super Champion variant is fitted with a bronze bushing bearing, a bearing type proven in heavy industrial block applications for its high load-bearing capacity, durability, and resistance to contamination and harsh field conditions encountered during sustained heavy use. The snatch block configuration features a side-opening cheek plate, allowing the block to be attached to or removed from a wire rope at any point along its length without threading the line — an essential operational feature in large-scale rigging setups where efficiency and ease of rigging are critical.
McKissick's Super Champion designation reflects a reinforced, high-capacity construction standard within their block product line, purpose-built for demanding applications where standard blocks would be insufficient. The Series 430 at 30-ton capacity is commonly deployed with heavy cranes, winches, and pulling systems in oilfield, offshore, and heavy construction environments to redirect wire rope leads or to develop mechanical advantage in large tackle assemblies. All shackles, hooks, and attachment hardware used with this block must be rated to match or exceed the 30-ton working load limit to ensure a safe and compliant rigging system.
