The kingpin is the most critical component used in the load transfer from semi trailer. 1.Making a selection The d-value and the thickness of the welding late are two considerations in making a kingpin selection for a semi trailer design. The actual d-value of the selected kingpin must be larger than the calculated d-value. Then you can determine the thickness of the skid plate. The kingpin d-value and recommended skid plate thickness are stamped at the bottom of the kingpin. 2.Kingpin installation Welding on a channel support for the 2 inch welded king pin, must be more than 110mm between welds. 3.Kingpin operation Operation of the semi trailer will cause normal wear on the kingpin, due to abrasion.
