Washer for Demag AC80-1

The washer 340 644 99 is a fastening component engineered for the Demag AC80-1 crane. It is used within various bolted assemblies throughout the machine to support mechanical connections. By distributing the clamping force of a bolt or nut over a larger surface area, this component helps protect the mating surfaces from localized stress and deformation during operation.

This part is specifically designed for the Demag AC80-1 crane. It is intended for use in maintenance and repair procedures where precise fastening is required to maintain the machine's structural stability. As an element of the crane's hardware, it ensures that bolted joints remain secure under the dynamic loads and operational conditions typical of heavy lifting equipment.

Washers are standard mechanical components that serve several functions in heavy machinery. They provide a smooth bearing surface for fasteners, help distribute axial loads, and can act as spacers to adjust the grip length of a bolt. In complex equipment like cranes, these components are necessary to maintain the tension and security of threaded joints, ensuring that assemblies remain tight despite the vibrations and forces encountered during daily operation.
