Fifth Wheel Assembly, Sliding
SAF-Holland

This sliding coupling platform delivers robust, long‑life performance for heavy‑duty tractor‑trailer applications. Built around a durable kingpin interface and precision‑machined rails, it provides controlled fore‑aft travel with a reliable locking mechanism that maintains alignment under load, vibration, and high‑speed highway conditions. The design emphasizes consistent contact with the mating surfaces during coupling and uncoupling, reducing wear on critical mating components and improving stability when traversing uneven surfaces or crosswinds. By enabling adjustable positioning, it accommodates a range of trailer footprints and kingpin locations, which translates into faster dock side alignment, simpler retrofits, and reduced maintenance downtime. The asset is identified within the VMRS 059‑001‑135 family, ensuring standardized service and compatibility guidance across fleets and repair networks. In fleets, the system supports modular installations with common mounting patterns, enabling straightforward replacements and recognizable part numbers for stock management. Key benefits include improved pin engagement confidence, reduced side‑load chatter, and extended service life through corrosion‑resistant finishes and tight tolerances. Overall, this solution enhances reliability in demanding environments, supports safer operation during coupling, and contributes to lower lifecycle costs for premium, road‑used applications.
