McKissick 751 Series Bridge Crane Block - 3 Ton - 1/2 in Wire Rope - 8 in Sheave

Product Description

The McKissick 751 Series Bridge Crane Block is a heavy-duty overhead lifting block engineered for industrial crane applications where a single-groove configuration is required. Designed for use with bridge cranes and overhead crane systems, this block delivers reliable performance in environments where consistent load control and durability are essential. The 751 Series is part of McKissick's established line of overhead crane blocks, offering a single-sheave design suited to straightforward reeving arrangements on bridge and overhead crane systems.

This block is rated for a 3 ton capacity and is designed to accommodate a maximum cable diameter of 1/2 in. The 8 in sheave outside diameter and single-groove configuration make this block well suited to crane setups where a simple, direct reeving arrangement is preferred or required. The overall dimensions of 16.88 in H x 8.94 in W x 2.75 in THK give this block an exceptionally slim thickness profile, a defining characteristic of the single-groove 751 Series design that makes it particularly advantageous in crane structures where lateral clearance is a critical constraint.

The 751 Series overhead block is built to withstand the repetitive duty cycles common in manufacturing facilities, warehouses, steel service centers, and other industrial operations. Its construction supports smooth cable travel across the sheave groove, reducing wear on both the cable and the block during extended use. The 1/2 in maximum cable diameter at the 3 ton rating is among the larger wire rope specifications available in this series at this load level and should be confirmed against McKissick documentation and the crane system's installed wire rope before ordering.

Note:

Material composition and finish details should be confirmed against the official McKissick 751 Series product documentation or catalog prior to specification. The single-groove configuration and slim 2.75 in THK profile distinguish this block from the 2-groove 752 Series variants and should be selected based on the reeving requirements and clearance constraints of the crane system. The 1/2 in cable diameter at the 3 ton rating should be confirmed against McKissick documentation and the crane system's installed wire rope before ordering. Do not assume certifications or standards compliance without verification from McKissick or an authorized distributor.
