Cotter pin for Palfinger

The EK867 cotter pin serves as a mechanical fastener within Palfinger machinery. Its primary function is to secure the position of pins, nuts, or shafts, preventing unwanted rotation or axial movement. This component ensures that mechanical joints remain stable, particularly in equipment subjected to regular vibrations and dynamic loads during operation.

This part is utilized in various Palfinger articulated cranes, forklifts, and lifting systems. It is typically installed at key articulation points, on the ends of hydraulic cylinder pins, or within locking mechanisms where additional security against loosening is required. The design features two shanks that are bent after insertion to provide effective mechanical retention within the bolt hole.

Cotter pins function as a secondary locking device for primary fasteners such as clevis pins or slotted nuts. By passing through a pre-drilled hole in a shaft or bolt, the pin prevents the primary fastener from backing out of its assembly. Regular inspection of these pins is standard practice during maintenance to ensure the continued integrity of structural connections and to prevent the disconnection of machine components.
