JOST coupling systems use cutting edge electronic technology to increase safety, comfort and efficiency in all operations. The following variants are currently available for different demands:

  • Automatic coupling system (KKS)
  • Sensor coupling system (SKS)
  • Sensor fifth wheel coupling (sensors)
  • LubeTronic 5- and 1Point
  • King Pin Finder

JOST KKS is the ground-breaking automatic coupling system, which is revolutionising the coupling process. The tried-and-tested components – including the JSK 42 fifth wheel coupling, the Modul E-Drive landing gear, SKS, sensors, King Pin Finder and LubeTronic – form a complete system which no longer requires the driver to climb, crank or plug.

In the SKS sensor coupling system, three sensors constantly monitor the status of the fifth wheel coupling. The coupling is opened comfortably and in a time-saving manner using a remote control in the driver‘s cab. The sensor fifth wheel coupling system also permanently monitors the locking position via sensors, displaying the position via remote display in the driver’s cab.

The coupling systems are supplemented by LubeTronic, the automatic lubrication systems which are available for both standard and low-maintenance fifth wheel couplings. These systems reduce both the effort required for subsequent greasing, as well as the amount of grease. The biodegradable, high-performance lubricant is not only easy on the wallet, but also on the environment.

The optional King Pin Finder, a high-resolution camera in the JSK 42 fifth wheel, also enables a precise image when maneuvering backwards. This provides additional safety when hitching up.
