The Super Champion 431 hinge block, part number 121111, serves as a primary component in rigging systems for cranes and heavy lifting equipment. By incorporating a sheave, this block allows for the redirection of wire rope and assists in mechanical advantage during lifting tasks. It comes equipped with an integrated shackle to facilitate secure attachment to anchor points or other lifting hardware. The unit is manufactured by McKissick.
This specific model features a 10-inch sheave diameter and is rated for a 20-ton load capacity. It is engineered to operate with 1-1/8 inch diameter wire rope and utilizes a roller bearing to support the rotation of the sheave during use.
In heavy machinery, blocks of this type are used to manage the tension and path of hoist lines. The sheave provides a grooved surface that supports the wire rope, while the internal bearing reduces rotational friction, ensuring smooth movement under load. Proper maintenance and regular inspection of the sheave groove, bearing, and shackle are necessary to ensure the continued functionality of the rigging assembly.
