Cotter pin for American Crane 9310

The cotter pin 804925 serves as a locking component within the A-frame assembly of the crane. Its primary function is to secure other fasteners, such as slotted nuts or bolts, by preventing accidental rotation or loosening during operation. By maintaining the integrity of these connections, the pin helps ensure the stability of the structural assembly that supports the boom and manages load distribution.

This component is compatible with the American Crane 9310 model. It features a diameter of 5/8 inch and a length of 4 inches, designed to fit specific fastening points within the machine structure. The pin is inserted through a pre-drilled hole in a bolt or shaft and bent to create a mechanical lock.

Cotter pins are standard hardware used in heavy machinery to provide a simple, effective method for retaining pins and nuts in place. They prevent fasteners from vibrating loose, which is critical for maintaining the structural alignment of crane components during lifting tasks. Regular inspection of these pins is standard practice to ensure that all primary fasteners remain properly secured.
