Bolt and washer for Demag AC80-1

The bolt and washer set, part number 978 340 73, functions as a fastening assembly for the Demag AC80-1 all-terrain crane. These components are used to join and secure structural and mechanical parts, providing the necessary clamping force to maintain assembly integrity. The bolt provides the required tension, while the washer distributes the load under the bolt head to protect the mating surface and assist in maintaining fastener security during operation.

This assembly is compatible with the Demag AC80-1 crane and is utilized in various positions across the machine, including the attachment of body panels, chassis components, or counterweight systems. Proper installation of these fasteners ensures that components remain securely attached despite the dynamic loads and vibrations inherent in crane operation.

In heavy machinery, bolts and washers are utilized to create rigid connections between machine sections. The bolt provides the primary mechanical link, while the washer prevents damage to the surface of the joined parts and helps maintain consistent torque settings by distributing pressure evenly. Regular inspection of these fasteners is necessary to ensure the structural stability of the equipment.
