Lock washer for Demag AC80-1

The lock washer, part number 771 164 00, serves as a fastening component for the Demag AC80-1 crane. It is engineered to maintain tension within bolted assemblies, ensuring that nuts and bolts remain secure during the operation of the machine. By exerting a constant force against the fastener, it helps prevent the loosening that can occur due to the vibrations, impacts, and dynamic loads inherent in crane operation.

This component is compatible with the Demag AC80-1 model. It is used in critical structural joints where maintaining torque is necessary for the integrity of the assembly, such as within the chassis, boom, or rotation systems. The actual manufacturer for this component is Demag.

Lock washers of this type are used throughout heavy machinery to secure threaded fasteners. They function by creating a spring-like resistance that increases the friction against the mating surfaces, effectively locking the fastener in place and protecting the structural integrity of the machine's various systems.
