KKS (Automatic coupling system)

The JOST KKS enables the driver to couple and decouple the semi-trailer via remote control without leaving the driver’s cab. The JSK 42 fifth wheel coupling, the Modul E-Drive landing gear, SKS, sensors, King Pin Finder and LubeTronic components form a complete system which saves time when coupling, as well as increases safety, efficiency and ergonomics.

The driver is guided through the fifth-wheel process process and with the help of the sensors and the King Pin Finder, he receives live information about the coupling status on the KKS remote control in the driver‘s cab at any time. Furthermore, the driver can operate the landing gear and fifth wheel coupling locking mechanism from the cab, significantly reducing the coupling duration and number of times needed to get in and out of the cab. It is of course possible to introduce the KKS step-by-step into to the fleets, as the operation in mixed fleets is possible.

The KKS is particularly suited for transport companies which often perform coupling processes and drive short distances, such as those in on-site operations, as the time advantages here are particularly beneficial from a financial standpoint.

KKS Automatic coupling system

Benefits at a glance

Ergonomics and health

  • No need to climb onto the catwalk
  • No more cranking of landing gears, automatic operation
  • No more manual mounting of the fifth wheel coupling
  • Less frequent entry and exit prevents fall accidents

Time saving of up to 50 %

  • No more need for cranking, connecting and disconnecting supply lines or opening the fifth wheel, thus freeing up time for other important tasks

Safety

  • KKS and sensors prevent trailer loss
  • Wrong coupling is no longer possible: when the trailer is supplied with electricity, the king pin is in the fifth wheel coupling
  • The driver cannot become trapped between truck and trailer
  • No more workplace accidents caused by careless climbing
  • Standard pneumatic cylinder always allows effortless opening of the fifth wheel coupling, even when the tractor-trailer is twisted
  • Three sensors are built in as standard, for sensing the king pin, trailer plate and fifth wheel lock
  • The landing gear is always moved all the way up, thereby preventing damage
  • Easy reverse maneuvering thanks to the optional King Pin Finder

Further advantages

  • Simple coupling and decoupling, even when it is raining, snowing or during darkness
  • Relieves time pressure on the driver, resulting in less stress and fewer errors
  • Reduced space requirement, as cranking the landing legs is no longer necessary
  • Increased convenience for the driver
  • Of course, operation in mixed fleets is also possible; therefore, the JOST KKS can be introduced step-by-step
  • Standardised plug certified to ISO 13044-2 makes the system future-proof
  • Supply connections for truck and trailer remain intact
  • Costs can be reduced, as the catwalk, supply lines and side flaps are no longer needed
  • Can be reliably deployed for transporting dangerous goods thanks to ADR certificate
  • Approved as per ECE R55-01 and ECE R13
  • Lower CO₂ emissions due to less idling

JOST KKS is a revolutionary product which will permanently change the logistics sector, thanks to the time, comfort and safety gains enabled through a single product.

The complete automation of manual, time-consuming and strenuous processes enhances safety, efficiency and ensures greater satisfaction amongst drivers in today’s fleets. A huge advancement, particularly in times of demographic changes and a lack of drivers!
