Washer for Liebherr LTM 1070-4.1

The washer, part number 10 28 97 95, is a fastening component used in Liebherr mobile crane assemblies. Its primary function is to distribute the clamping force of a bolt or nut over a larger area, which helps protect the contact surface of the joined components and maintains the integrity of the connection. This component is specified with a hardness rating of 300HV. It is engineered for precise fitment on the Liebherr LTM 1070-4.1 all-terrain crane. By providing a stable bearing surface, the washer helps prevent localized stress concentrations that can occur under high-load conditions during crane operation. Washers are standard mechanical elements used throughout heavy machinery to support fastening systems. They function by creating a flat surface for fasteners to seat against, which assists in maintaining consistent tension across the joint. Proper selection of a washer based on its hardness and dimensions is necessary to ensure that the load is distributed correctly, preventing the fastener from loosening or damaging the surrounding material during the operational cycles of the machine.
