Fifth Wheel Assembly
SAF-Holland

A high-capacity fifth-wheel assembly variant designed to handle substantial vertical loads while maintaining precise king-pin alignment. The maximum vertical load specification of 55,000 pounds indicates suitability for heavy tractor-trailer combinations frequently found in regional hauls and bulk-commodity transportation. The additional dimensional detail specifies a 2-inch king-pin diameter, which aligns with standard king-pin configurations on conventional semi-trailers, simplifying compatibility with a wide range of trailers. This variant’s build supports consistent release and engagement forces, minimizing drive-line misalignment and hitch wear during dynamic maneuvers. The VMRS code 059-001-135 anchors this part in the SAF-Holland part system for streamlined maintenance planning, while the integration with left-hand release geometry enhances operator ergonomics and controllability in tight coupling scenarios. Cross-references are not listed for this item, but the design is compatible with common stationary mounting plates and standard mid-body frames used in mainstream fleet equipment. Category context: fifth wheel assemblies, optimized for standard/moderate applications with emphasis on load capacity and reliable king-pin engagement.
