Parallel pin for Demag AC80-1

The parallel pin, part number 345 630 99, is a cylindrical component engineered for the Demag AC80-1 mobile crane. It functions as a locating element within the machine's assembly, ensuring the precise positioning of connected parts. By fitting into machined holes with tight tolerances, this pin maintains the relative orientation of components and resists lateral shear forces that occur during crane operation.

This component is compatible with the Demag AC80-1 model. It is designed to be installed in joints, hinges, or other critical connection points where maintaining exact alignment is necessary to prevent displacement under load. The pin ensures that mating surfaces remain stable and accurately positioned throughout the operational cycle of the crane.

In heavy machinery, parallel pins are used to align separate parts during assembly and to secure their relative position. Unlike fasteners that rely on tension, these pins provide structural support against shear stress, helping to prevent movement between components that could otherwise lead to mechanical misalignment or increased wear in the surrounding assembly.
