OB 12 hook assembly for Gunnebo-Johnson

The OB 12 hook assembly, part number 5865, serves as a connection point in crane rigging and load handling systems. It connects the lifting cable or chain to the load, maintaining a secure attachment during lifting and positioning operations. This component is designed to manage tensile forces during standard crane cycles.

This hook is manufactured by Gunnebo-Johnson and is compatible with a wide range of industrial cranes, mobile cranes, and tower cranes, including equipment from brands such as Manitowoc, Terex, and Grove. The OB 12 designation indicates its specific classification within the manufacturer's rigging product line. The assembly includes a safety latch to assist in keeping the rigging hardware secured within the hook throat during operation.

Lifting hooks act as the final interface between the crane's hoist system and the load. They are engineered to support vertical lifting forces and are subject to regular safety inspections to check for deformation, throat opening, or wear on the saddle. Proper maintenance of the hook and its safety latch mechanism is required to ensure the integrity of the lifting connection.
