Cotter pin for Liebherr 112ECH 8-43024

The cotter pin 433009201 serves as a mechanical fastener used to secure components in position and prevent relative movement or accidental separation of parts. It is designed to pass through a hole in a shaft or bolt, where its ends are bent or expanded to create a positive lock. This component is used in assemblies where vibration or load could otherwise cause nuts to loosen or joints to separate.

This part is compatible with the Liebherr 112ECH 8-43024 tower crane. In these crane systems, such fasteners are typically employed to secure bolts in structural joints, slewing mechanisms, or hoisting systems, ensuring that critical components remain firmly connected during operation. Proper installation involves inserting the pin through the designated hole and securing the ends to maintain the integrity of the connection.

Cotter pins function as a locking mechanism in various mechanical assemblies. By preventing the rotation or withdrawal of pins and bolts, they maintain the structural alignment of the machine. Regular inspection of these fasteners is standard practice to ensure that all connections remain secure and that no components have shifted due to operational stresses.
