Slide Base
SAF-Holland

The slide base serves as the foundational interface for sliding fifth‑wheel assemblies, providing a stable platform on which adjustment, alignment, and movement occur. It contributes to precise positioning of the hitch relative to the tractor, enabling optimized weight distribution and trailer maneuverability. VMRS code 059-001-003 designates its place within the slide mechanism category, while category context ties it to SAF-Holland’s sliding base components used in a wide range of highway and vocational applications. Benefits include smooth, repeatable sliding action, accurate indexing for quick coupling, and robust support for heavy loads during dynamic driving conditions. Practical applications span fleet operations where quick adjustment of kingpin position is necessary to accommodate varying trailer lengths, axle configurations, or operator preferences, all while maintaining structural integrity and service life.
