Inner disc for Grove TR522

The inner disc 9904103987 functions as a mechanical interface within the brake or clutch assemblies of heavy machinery. It is designed to engage with corresponding discs or plates to manage the transfer of power or to initiate braking force. By creating necessary friction, this component enables the operator to control the motion of the crane, whether through the transmission system, wheel brakes, or the superstructure swing brake.

This component is specifically configured for use in the Grove TR522 rough-terrain crane. It is engineered to meet the mechanical requirements of the brake and clutch systems found in this model, ensuring proper fitment and engagement within the housing. Maintenance technicians should inspect these discs for signs of wear to ensure the continued responsiveness of the crane's braking and drivetrain systems.

In heavy equipment, discs of this type are subjected to significant compressive forces and thermal loads during operation. They provide the friction surface required to stop movement or engage drive components. Proper alignment and surface contact are necessary to maintain the operational control of the machine's primary systems.
