Outer disc for Demag AC 300

The outer disc, part number 80689873, serves as a mechanical component within the transmission or braking systems of the Demag AC 300 all-terrain crane. It is typically integrated into multidisc brake assemblies or clutch packs found in the crane's winch or slewing mechanisms. The disc facilitates the transmission of torque or the generation of friction required to control, decelerate, or stop the movement of heavy loads during crane operations.

This component is specifically engineered for the Demag AC 300 crane model. In a multidisc system, the outer disc works in conjunction with inner discs to create the necessary contact surface area for effective engagement or braking. Proper alignment and surface integrity of the disc are necessary to maintain consistent friction coefficients and to ensure that the system operates according to the machine's original design specifications for load control and safety.

In heavy machinery, these discs are part of the power transmission or braking circuit, where they are subjected to mechanical forces and thermal energy during operation. Their primary function is to provide a reliable interface for torque transfer or to convert kinetic energy into heat during braking, allowing for precise control of the crane's lifting and rotating functions.
