Top Plate
SAF-Holland

The top plate serves as a critical load-bearing interface within pneumatic and hydraulic actuation assemblies for heavy-truck couplings. Its function is to provide a stable, flat mounting surface that distributes forces from the actuators, latches, and cylinders across the assembly, ensuring proper alignment and consistent engagement across multiple operating cycles. Classified in the 42517 category, it sits alongside other core structural components that establish the backbone of release and control hardware. VMRS 059-001-001 places it within a standardized top-plate family that supports interchangeable interfaces and predictable maintenance scheduling. While the provided data does not list additional features, the top plate typically accommodates bolt patterns and tolerance stacks that influence how precisely the release system engages, how evenly loads are shared during locking, and how easily technicians replace worn components during overhauls or upgrades. In practical terms, a robust top plate contributes to longer service life, reduced maintenance downtime, and improved reliability in high-usage fleets.
