The cotter pin, part number 509 884 98, is a safety component used in the Demag AC80-1 crane. Its primary function is to lock castle nuts, clevis pins, and other hardware in place, ensuring that these fasteners do not back off or disconnect due to operational movement and vibration. This component is used across various systems within the crane, including structural articulations and steering or braking assemblies, where maintaining a secure connection is required for safe machine operation.

This part is designed for compatibility with the Demag AC80-1 model. Proper installation and regular inspection of these pins are standard maintenance procedures to ensure the integrity of the machine's fastening systems.

In mechanical assemblies, a cotter pin acts as a mechanical lock by passing through a pre-drilled hole in a shaft or bolt. Once inserted, the legs are spread to prevent the pin from sliding out, thereby securing the nut or pin it retains. This simple yet effective locking mechanism is widely used in heavy machinery to maintain the tension and position of critical assembly hardware.
