Heavy Duty Fifth Wheel Couplings

Fifth Wheel Couplings (Heavy Duty)

heavy duty fifth wheel coupling

Fifth wheel couplings are fitted to a tractor unit to connect it to the trailer. Fifth wheel couplings are vehicle attaching parts that are subject to mandatory design approval and on which the highest safety requirements are placed. We can supply a suitable fifth wheel coupling for all applications, thus always guaranteeing a sage and secure link between the tractor and the trailer. Below is a list of fifth wheel couplings supplied by JOST Australia.
