Washer for Liebherr LTM 1070-4.1

The washer with part number 10 87 56 47 serves as a mechanical fastening component within the Liebherr LTM 1070-4.1 mobile crane. Its primary function is to distribute the load from a fastener, such as a bolt or nut, over a larger surface area, which helps reduce localized pressure on the underlying material. By spreading this force, the washer protects the contact surfaces from damage during the tightening process and helps maintain the integrity of the bolted joint.

This component is specifically engineered for the Liebherr LTM 1070-4.1 and meets a hardness specification of 200HV. It is utilized in various critical bolted connections throughout the machine, including structural assemblies and the mounting systems for hydraulic or electrical components. Proper installation of this washer ensures that the clamping force is distributed evenly, which is necessary for the stability of the crane's mechanical systems.

In heavy machinery, washers act as spacers or load-bearing interfaces between a fastener head and the machine frame. They are essential for preventing the fastener from sinking into the surface and for maintaining the required preload in the joint. By ensuring a secure fit, the washer helps prevent the loosening of connections that can occur due to operational stress.
