Stop washer for Demag AC-395

The stop washer 956719 acts as a mechanical locking device within the assembly of Demag cranes. Its primary function is to secure nuts, bolts, and other fasteners, preventing them from loosening when subjected to the dynamic loads and operational vibrations characteristic of heavy lifting equipment. By maintaining the required tension in a joint, this component supports the structural integrity of various crane systems, including the slewing mechanism, boom assemblies, and undercarriage components.

This component is specifically compatible with the Demag AC-395 all-terrain crane, including the AC-395 Serie-76011 U150 model. Proper installation of this washer is necessary during the assembly or maintenance of critical joints where fastener security is required to prevent misalignment or component displacement during crane operation.

In mechanical engineering, stop washers are used to provide a positive lock for threaded fasteners. These components often feature tabs or specific geometries that engage with the mating surface or the fastener head to resist rotation. By ensuring that connections remain tight, the washer helps prevent the secondary effects of fastener migration, such as increased vibration or accelerated wear on connected parts within the machine.
