Cotter pin for American Hoist 9299

The cotter pin part number 804927 is a mechanical fastener used to secure various components such as nuts, bolts, shafts, or pins within the American Hoist 9299 crawler crane. By inserting the pin through a hole and bending its legs, it prevents the primary fastener from backing out or shifting position during the heavy-duty operation of the crane. This component is designed with a diameter of 5/8 inch and a length of 6 inches to ensure a proper fit in the designated assembly points.

This component is compatible with the American Hoist 9299 lattice boom crawler crane. It is often utilized in critical connections, such as those found in the boom assembly, counterweight systems, or crawler track mechanisms, where maintaining the integrity of the connection is necessary for safe operation. The part is manufactured to meet the specific dimensional requirements for these heavy machinery applications.

Cotter pins function as a secondary locking device in mechanical systems. They are installed to provide a simple yet effective method of retaining hardware, ensuring that primary fasteners remain seated even under vibration or dynamic loads. Regular inspection of these pins is standard practice to ensure they remain properly seated and free from deformation.
