Fifth wheel couplings and mounting plates
JOST submitted the patent application for the first cast steel fifth wheel coupling almost 60 years ago. Since then, JOST’s fifth wheel couplings have been a success story around the world. All renowned vehicle manufacturers put their trust in JOST’s expertise and performance.
The extensive product range and high quality are just as crucial for the customer’s trust as the company’s innovative skill and reliable global supply of finished and spare parts.
JOST provides fifth wheel couplings for any application. This includes weight-optimised pressed metal and robust cast steel couplings for imposed loads between 6 and 74 tonnes. Almost all variants are available with a large selection of pedestals in all common heights and with all common hole patterns for plate and frame assembly. Depending on the model and height, it is possible to reduce the weight by up to 100 kg. Different sensory variants that build on one another guarantee secure operation under all conditions, while the automatic lubrication solutions brought together in the LubeTronic product family save time and money.
Design / features
JOST’s range includes the perfect fifth wheel coupling with the required imposed load for a wide range of applications – from lightweight distribution traffic to normal road transport; from site traffic to heavy duty transport.
