King pin

King pin festures 1.Manufactured from high tensile drop forgings and heat-treated 2.Available in bolt-on series and welded series 3.Complied with australia standards as2175-1995 and australian design rule adr62/01 Kingpin instruction The function of the kingpin is to engage the semi trailer to the fifth wheel. 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.
