FW33J736XL00
Fifth Wheel Assembly, Sliding
SAF-Holland

Engineered for deep-duty service, this sliding mount variant emphasizes high vertical load capacity and rugged kingpin engagement. The presence of a 55,000-pound maximum vertical load indicates a strong ability to bear dynamic loads during acceleration and braking while maintaining a reliable pin engagement under lateral loads. The 2-inch kingpin diameter ensures compatibility with standard trailer fittings, and the explicit load specification supports predictable service life and maintenance planning. The left-hand release feature improves operator ergonomics and reduces effort during routine coupling operations, while the slider mounting type permits fine-tuned fore-aft adjustment to align with different tractors and tandem configurations. The low-lubricant variant reduces lubrication requirements and simplifies maintenance intervals in harsh environments. VMRS 059-001-135 places this unit in the same family of heavy-duty hitching systems, enabling accurate maintenance documentation and part-tracking across fleets. Cross references are not listed, but compatibility with typical 2-inch kingpin configurations and standard 42518 fleet installations is expected. This design is well-suited for long-haul, regional, and vocational duty cycles where uptime and reliability are critical to operations.
