McKissick 752 Bridge Crane Overhead Block - 5/8 in - 15 Ton - 12 in

Product Description

The McKissick 752 Bridge Crane Overhead Block is a heavy-duty double-groove overhead block engineered for bridge crane and overhead lifting applications in industrial facilities, manufacturing plants, steel mills, and heavy fabrication environments. Rated for a 15-ton working load limit, this block is built around a 12-inch outside diameter sheave with 2 grooves, accommodating wire rope cable up to 5/8 inch in diameter. With overall dimensions of 25.38 inches high by 13.46 inches wide by 13.94 inches thick, this configuration is taller and thicker than the 10-ton variant at the same sheave diameter, reflecting the additional structural material required to safely handle the increased working load limit in continuous-duty overhead crane service.

The double-groove sheave configuration allows this block to accommodate two wire rope runs simultaneously, supporting multi-part line reeving arrangements commonly used in bridge crane systems to achieve the mechanical advantage required for lifting heavy loads with controlled, stable load handling. The 12-inch sheave diameter provides a suitable rope bend radius for the 5/8-inch wire rope accommodated by this block, supporting rope longevity during the high-cycle lifting operations typical of industrial bridge crane service. The overall block dimensions reflect the robust construction required to safely handle 15-ton working loads in continuous-duty overhead crane environments.

The McKissick 752 is designed to meet the demanding requirements of overhead bridge crane service, where consistent, dependable block performance across repeated lifting cycles is essential for safe and efficient facility operations. This 15-ton configuration offers a higher working load limit than the 10-ton variants at the same 12-inch sheave diameter, making it well suited for installation in higher-capacity bridge crane, gantry crane, and overhead hoist systems in steel mills, manufacturing plants, heavy fabrication shops, and industrial facilities where greater lifting capacity is required.
