McKissick 751 Bridge Crane Overhead Block - 5/8 in - 7.5 Ton - 12 in

Product Description

The McKissick 751 Series Bridge Crane Block is a heavy-duty overhead rigging block designed for reliable performance in industrial crane and hoist applications. Rated at 7.5 tons, this block is well-suited for bridge crane systems operating in manufacturing plants, steel mills, fabrication shops, and other heavy industrial environments where dependable single-line overhead lifting is required at higher capacities. The 751 Series represents McKissick's commitment to producing rigging components that combine strength and precision in a practical, field-proven form factor across a wide range of capacities.

This block features a 12-inch sheave outside diameter with a single groove, accommodating a maximum cable diameter of 5/8 inch. The single-groove sheave design provides straightforward single-line reeving for clean, direct lifting applications. The 12-inch sheave diameter provides an excellent D:d ratio relative to the 5/8 inch cable, significantly reducing wire rope fatigue and extending rope service life under repeated load cycling. Overall dimensions of 25.44 in H x 13.44 in W x 4.25 in THK give this block a notably slim profile for its sheave size and capacity, making it particularly well-suited for bridge crane installations where lateral clearance between crane girders or structural members is a critical constraint.

The 751 Series block is engineered for overhead crane service and integrates with standard bridge crane rigging configurations. Its slim-profile construction makes it especially practical in tight overhead installations where a high-capacity single-line block with a large sheave diameter is required without the added width of a multi-groove configuration. As with all crane blocks in this capacity range, proper installation, routine inspection, and strict adherence to the rated working load are critical to safe and effective operation.
