Plate disc for P&H 20 ton crane

The plate disc, part number 15E577D2, functions within the brake system of P&H heavy machinery. It acts as a friction surface to dissipate kinetic energy, allowing the operator to control the deceleration and stopping of the crane's mechanical movements, such as load hoisting or rotation. This component is designed by Harnischfeger Corp. and is specified for use in 20-ton capacity cranes, specifically those matching the HBB-6-2 parts list and series CAX-29783.

Brake discs of this type are engineered to maintain consistent contact with friction materials, ensuring the necessary torque to hold or slow the machinery during operation. Maintaining the integrity of these discs is necessary for the proper function of the braking assembly, as they must handle the thermal and mechanical loads generated during the braking process. By providing a flat and stable surface, the disc ensures that the brake system responds effectively to operator inputs, which is necessary for the safe handling of loads and the overall stability of the crane during its duty cycle.
