A kingpin is a heavy metal cylindrical pin that is located underneath the front end of the trailer. The kingpin is the mechanism on the trailer that locks it to a road tractor. It is typically positioned between 18" to 48" from the trailer nose.
A greased metal grid plate surrounds the kingpin. This grid plate allows the fifth wheel to slide underneath the trailer.
When the tractor is backed into the nose of a trailer, the fifth wheel pivots and slides underneath the trailer's grid plate.
The fifth wheel then locks onto the trailer's king pin.
