The safety pin is a locking fastener used to secure components on the Demag AC80-1 all-terrain crane. It functions as a clevis pin with an integrated locking mechanism, designed to keep parts connected and prevent them from shifting or disconnecting during crane operation. This component is typically found in applications requiring frequent assembly and disassembly, such as securing pins in the boom structure, outrigger systems, or other critical articulation and anchor points on the machine.

This specific component is compatible with the Demag AC80-1 model. The design of the pin allows for manual insertion and removal while the integrated locking loop ensures the fastener remains secure even when the machine is subjected to vibrations or dynamic loads during lifting tasks. By maintaining the integrity of these connection points, the pin helps ensure the stability of the crane assembly.

In heavy machinery, safety pins of this type act as a secondary retention method for primary pins or shafts. They provide a simple yet effective way to lock components in position, ensuring that primary fasteners do not back out or disengage while the equipment is in service.
