New kingpin system from SAF-Holland

SAF-Holland kingpin systemSAF-Holland introduces its new removable and replaceable HOLLAND 2-in. AAR King pin system for hot dip galvanized upper couplers.

Designed to meet AAR specifications, SAF-Holland says the patented system features a specially machined king pin housing and king pin. The king pin housing is welded into the upper coupler of the trailer prior to the hot dip galvanization process allowing for complete and uncompromised upper coupler corrosion protection.

After galvanization, the replaceable HOLLAND AAR King pin is precisely secured into the housing with a special nut and collet fastener, allowing the kingpin to remain removable and replaceable over the life of the trailer. Because the AAR King pin is installed in the upper coupler following the hot dip galvanizing process, SAF-Holland says it is not exposed to harsh chemicals and temperatures during the hot dip galvanized process.

“This new AAR Kingpin System answers the OEM’s challenges of hot dip galvanizing upper coupler assemblies by allowing the king pin to be installed after the galvanizing process. This design allows for the easy removal and replacement of the king pin for dealers, fleets and OEMs,” says Jeffrey Talaga, vice president of sales and development, Americas.

In addition to providing long-term integrity of the galvanized coating, SAF-Holland says the new AAR King pin can be easily and quickly removed and replaced, saving time and money over the life of the trailer. The system is designed to be compatible with ¼-in., 5/16-in., and 3/8-in. bolster plates, utilizing the same housing and different length king pins to accommodate the thickness variations.
