The fifth wheel plates give the connection between the towing truck and the semi trailer hitch, tractor unit, dolly or driving trailer. Few entertaining vehicles utilize a fifth wheel arrangement, obliging the pairing to be introduced at the bottom of an elevated truck like a lugging vehicle. To decrease contact, oil is connected to the surface of the fifth wheel. The setup is once in a while called a turn-table in Australia and New Zealand, particularly in the event that it is a pivoting ball-race-bearing sort. The upside of this coupling is enhanced towing steadiness.
