McKissick 751 Series Bridge Crane Block - 3 Ton - 3/8 in Wire Rope - 8 in Sheave

Description du produit

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 3 tons, this block is well-suited for bridge crane systems operating in manufacturing plants, fabrication shops, warehouses, and other industrial environments where dependable single-line overhead lifting is required. 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 range of capacities.

This block features an 8-inch sheave outside diameter with a single groove, accommodating a maximum cable diameter of 3/8 inch. The single-groove sheave design provides straightforward single-line reeving for clean, direct lifting applications. The 8-inch sheave diameter provides a favorable D:d ratio relative to the 3/8 inch cable, helping to reduce wire rope fatigue and extend rope service life under repeated load cycling. Overall dimensions of 16.88 in H x 8.94 in W x 2.75 in THK give this block a notably slim profile, making it well-suited for bridge crane installations where lateral clearance between crane girders or structural members is a consideration.

The 751 Series block is engineered for overhead crane service and integrates with standard bridge crane rigging configurations. Its slim-profile construction makes it particularly practical in tight overhead installations where a single-line block 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.
