Internal disc for Demag AC 300

The internal disc 80480373 functions as a friction element within the braking or clutch assemblies of heavy machinery. It is designed to interface with rotating components to either control motion or manage the transmission of power through the drivetrain or winch systems. By engaging with mating surfaces, this component allows for the precise stopping or coupling required during crane operations.

This part is specifically engineered for the Demag AC 300 all-terrain crane. It is intended for use in systems where friction-based engagement is required, such as wheel brakes, slewing drives, or transmission clutch packs. Proper installation ensures the intended mechanical interaction between the rotating and stationary parts of the assembly.

Internal discs of this type serve as the primary contact surfaces in wet or dry clutch and brake configurations. They are responsible for converting kinetic energy into thermal energy during deceleration or for transferring torque when engaged. Maintaining the integrity of these friction surfaces is necessary for the controlled operation of heavy lifting equipment.
