Washer 8 200HV for Liebherr LTM 1070-4.1

The 42 00 607 05 washer is a hardened component engineered to distribute the clamping force of a fastener across a wider surface area. By spreading this load, the washer helps prevent localized pressure and surface damage to the base material of the crane assembly. This component is specifically sized for an 8mm bolt or screw and carries a 200HV Vickers hardness rating, which defines its resistance to deformation under load.

This part is compatible with the Liebherr LTM 1070-4.1 all-terrain crane. It is typically utilized in structural connections where consistent tension and resistance to vibration are required, such as within the chassis, slewing system, or undercarriage components. Proper installation of this washer ensures that bolted joints maintain their integrity during the heavy-duty operation cycles typical of mobile crane equipment.

In heavy machinery, washers serve as a vital interface between the fastener head or nut and the mounting surface. They provide a smooth bearing surface that allows for uniform torque application and helps maintain the preload of the joint over time. Using the correct hardness specification is necessary to ensure the fastener assembly performs as intended within the machine's structural design.
