Fifth wheel couplings manufacturer Jost says it will now be equipping its JSK 37CW and JSK 42W low-maintenance units with LubeTronic automatic lubrication systems for the lock jaw as standard.
These couplings have top plate liners that allow greaseless operation of the coupling plate, as well as a plastic seal and maintenance-free joints or sliding bearings.
LubeTronic equipment is mounted directly on the fifth-wheel coupling and has an integrated supply of lubricant as well as battery-powered electronic control.
Jost says it will keep the lock jaw lubricated for three years or 300,000km, whichever comes first, supplying grease and ensuring reliable and safe functioning.
The company says its upgraded device is aimed at long distance trunking and tanker applications, as well as hazardous-cargo vehicles.
