FW70S924XL00
Fifth Wheel Assembly - Heavy Duty, Sliding
SAF-Holland

This heavy-duty sliding fifth wheel interface is engineered to provide a robust coupling solution between a tractor chassis and trailer for demanding freight operations. It delivers a substantial maximum load capacity of 79,366 lbs, supporting long-haul and heavy-haul applications with confidence. The platform footprint measures 35.75 inches in width and 63 inches in overall length, creating a broad, stable contact surface that distributes towing forces across a large area for improved stability and reduced wear. A travel range of 24 inches enables precise fore-aft adjustment to accommodate variations in tractor-trailer neck geometry, minimizing hookup effort and aligning kingpins with trailers across a wide operating envelope. Mounting height of 9 inches is compatible with common trailer neck heights, ensuring consistent coupling geometry across fleets. The inboard slide mount design contributes to torsional rigidity, reducing fore-aft play and enhancing steering feel during cornering while protecting the pin and plate from uneven wear. Category context highlights its role within SAF-Holland’s FW70 family and standard heavy-duty rails. In service, this unit supports faster, safer hitching, smoother towing dynamics, and predictable performance under high cyclic loads. Routine inspection of slide rails, bushings, and mounting hardware is recommended to preserve alignment and load distribution over time.
