Lock washer for Liebherr 112ECH

The lock washer, part number 423910501, serves as a mechanical fastener within the assembly of heavy machinery. Its primary function is to secure bolted joints against loosening caused by operational vibrations, impacts, or thermal fluctuations. By maintaining the necessary preload in these connections, the washer helps preserve the structural integrity of the equipment. It is utilized in various sections of the crane, ranging from chassis structural components to support systems and lifting mechanisms.

This component is specifically engineered for Liebherr equipment and is compatible with the 112ECH 8-43024 model. It is designed to integrate with specific screw and nut sizes to provide secure fastening and uniform load distribution. The part is manufactured by Liebherr to meet the precise fitment requirements of the specified crane model.

In heavy machinery, lock washers act as an interface between the fastener head or nut and the mating surface. They function by creating friction or applying a spring force that counteracts the rotational forces that lead to loosening. Proper installation of these washers is necessary to ensure the stability of critical joints throughout the machine.
