Fifth Wheel Couplings
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 safe and secure link between the tractor and trailer.

When mounting, using, converting or exchanging our fifth wheel couplings, the vehicle manufacturer’s notes, JOST instructions for mounting and use, and the relevant national regulations must be observed. In Germany these are §§19, 20, 21, 27 of the “StVZO” Motor Vehicle Safety Standards.
