Cotter pin for American Crane 9310

The 804861 cotter pin serves as a mechanical locking element within the assembly of the American Crane 9310. By inserting this pin through a pre-drilled hole in a bolt or shaft and bending the ends, it provides a physical barrier that prevents the primary fastener from backing out or shifting due to operational forces. This component is compatible with the American Crane 9310 lattice boom crane and features dimensions of 1/8 inch by 1 inch. It is designed to maintain the integrity of various mechanical connections throughout the crane, including those found in the boom sections, steering mechanisms, or braking systems.

In heavy machinery, cotter pins function as secondary retention devices to secure primary fasteners like clevis pins or slotted nuts. Their presence ensures that critical connections remain intact even when subjected to the dynamic loads and vibrations inherent in crane operation. Proper installation involves ensuring the pin is fully seated and the legs are bent sufficiently to prevent accidental removal. Regular inspection of these pins is standard maintenance practice to ensure all fasteners remain properly secured and to prevent the unintentional disassembly of machine components.
