Fifth Wheel Plate
SAF-Holland

Serving as the base interface for the fifth-wheel assembly, the plate distributes load from the connecting surface into the support structure while maintaining a flat, consistent seating plane for the mating plate. Its dimensions and mass properties are optimized to minimize localized stress concentrations while maximizing alignment stability during coupling and towing cycles. The part, coded within VMRS 059-001-001 and grouped under category 42763, functions as a primary anchoring element that transfers dynamic forces from the kingpin area through the mounting hardware and into the chassis. In practical use, technicians replace this component to restore uniform load distribution after wear or impact, ensuring the upper and lower interface surfaces maintain proper contour and contact. Compatibility with various fifth-wheel plate or slider systems is supported by standardization of hole spacings and thickness tolerances noted in the category guidelines. This element plays a pivotal role in sustaining towing performance, protecting adjacent components from excessive stress, and enabling reliable coupling across a fleet’s operations.
