Top Plate Assembly
SAF-Holland

This top‑plate assembly variant preserves the essential coupling surface and mounting interface while adapting to specific fleet requirements within the 42763 category. VMRS 059-001-001 anchors its function to the fifth‑wheel subsystem, enabling interchangeability with other assemblies in the same family and simplifying parts inventories for multi‑year fleets. The assembly combines precise geometry with rugged construction to withstand repeated hitching cycles, rough road conditions, and high misalignment scenarios. Benefits include consistent kingpin seating, reduced parasitic wear on jaws, and improved engagement reliability during cold starts or after extended idle periods. Applications span long‑haul tractors, regional fleets, and rental operations where standardized top‑plate interfaces are essential for uptime, predictable maintenance planning, and rapid replacement during routine service events.
