3 Proper usage
If they are subject to additional dynamic forces, for example if they
are used on uneven road surfaces or on construction sites, do not
use the complete fifth wheel load and D value, or use a heavier fifth
wheel coupling. Alternatively, consult JOST.
Every fifth wheel coupling has a serial number, which is embossed
on the type plate. This gives the coupling a unique identity.
