Fifth Wheel Top Plate
SAF-Holland

This platform element serves as the primary contact surface in the fifth-wheel interface, translating axle and vehicle chassis loads into the trailer coupling system. Its geometry supports precise kingpin seating and lock engagement, ensuring reliable hitch performance during dynamic driver maneuvers and load shifts. By maintaining tight tolerances on mounting surfaces and bolt holes, it distributes loads evenly and reduces uneven wear that can compromise alignment and safety. The no-lube configuration further simplifies upkeep while preserving stable friction characteristics across the service life, contributing to lower maintenance costs and faster turnarounds. Its application spans a wide range of heavy-duty operations, including fleets that regularly couple and uncouple in varying road conditions. The VMRS code ties this component to the standard fifth-wheel top-plate family, reinforcing compatibility with diverse chassis configurations that share common mounting patterns. Category context confirms its role as a core load-transfer element within the fifth-wheel assembly. Practical benefits include extended intervals between inspections, predictable wear, and dependable performance under both routine and challenging operating scenarios.
