Fifth Wheel Assembly, Sliding
SAF-Holland

In the 42518 category, this sliding interface delivers a robust fore-aft coupling solution designed for heavy-duty tractor-trailer operations. The sliding mounting mechanism enables precise navigation of the trailer tongue relative to the tractor, allowing operators to optimize tongue weight and turning clearance across varying loads and road conditions. With a VMRS code of 059-001-135, this assembly supports fore-aft adjustment during on-vehicle setup and trailer hookup, improving stability, reducing jackknife risk, and enhancing hitch alignment from start-up to shut-down. The design emphasizes reliability under rough-roading demands, with a focus on consistent engagement and smooth travel during long-haul cycles. Installers should verify compatibility with the tractor’s kingpin interface, ensure proper alignment with the trailer saddle, and follow maintenance intervals for slide rails and locking hardware to preserve smooth operation. In practice, fleets benefit from easier pickup and drop-off at the loading dock, quicker reconfiguration for mixed-use routes, and improved fuel economy through optimized tongue weight distribution. This configuration is suited for applications requiring dependable, adjustable coupling with standard heavy-duty trailers, delivering predictable performance across diverse operating environments while maintaining compliance with industry standards within the category 42518 ecosystem.
