Spring washer for Liebherr LTM 1070-4.1

The spring washer 42 40 005 08 serves as a fastening component within the Liebherr LTM 1070-4.1 mobile crane. It is engineered to maintain the integrity of bolted connections by providing a constant preload force, which helps counteract the loosening effects caused by operational vibrations and thermal expansion. By acting as a spring within the assembly, it ensures that fasteners remain secure under the dynamic loads typical of heavy lifting equipment.

This component is specifically compatible with the Liebherr LTM 1070-4.1 model. It is utilized in various structural and mechanical fastening points throughout the machine where maintaining precise torque is necessary for safe operation. Proper installation of this washer is important for the stability of the crane's chassis, counterweight systems, and other critical assemblies.

In general engineering, spring washers are used in bolted joints to prevent loosening and to compensate for wear or thermal changes that might otherwise reduce the clamping force of a fastener. They provide a reactive force that keeps the connection tight, thereby protecting the structural assembly from the effects of excessive movement or vibration during the machine's duty cycle.
