Flat washer for Liebherr LTM 1160-2

The flat washer, identified by part number 420000808, is a standard fastening component used within the assembly systems of the Liebherr LTM 1160-2 all-terrain crane. It functions by distributing the clamping force exerted by a bolt or nut across a wider surface area, which helps to protect the underlying material from localized pressure and deformation during tightening. By providing a uniform bearing surface, it ensures that mechanical connections remain secure and stable under the operational conditions typical of heavy lifting equipment.

This component adheres to the ISO 7089 A 5 A2C standard, specifying its dimensions and material properties for compatibility with the LTM 1160-2 crane model. The washer is designed to sit between the fastener head and the mounting surface, ensuring that the load is spread evenly across the joint. This configuration is standard for maintaining the integrity of various bolted connections throughout the crane structure.

In general engineering applications, flat washers are used to prevent damage to surfaces during the tightening process and to provide a smooth contact area for fasteners. They are essential for ensuring that torque is applied correctly to a joint, helping to maintain the structural stability of the machine by preventing the fastener from sinking into the material or loosening due to vibration.
