Couplings

General information
General information
The components used to couple vehicles and trailers are exposed to very high stress,
even during normal use. Regular service and maintenance is a prerequisite if the coupling is to function well for the duration of its service life.
The length of the service interval depends on the type of trailer, loads, road and climatic conditions, etc. The service should ideally be carried out in conjunction with other inspection of the vehicle, e.g. every 60,000 or 90,000 km.
If daily inspection or safety checks show that any of the wear limits have been exceeded or that the function of the product has been impaired, servicing must be carried out immediately.
If any of the product's wear limits have been exceeded, this is an indication that other parts also require servicing.
Check that all type plates and warning/information labels are legible and have not been painted over, washed off or otherwise damaged. Illegible labels must be replaced and can be ordered from VBG Truck Equipment GMBH.
If the coupling is damaged as a result of jackknifing, off-road driving or reversing, the vehicle must be stopped and the coupling replaced.
NB! All coupling equipment must be depressurised and de-energised before servicing is carried out. This means that you must disconnect the air supply and power to actuator-assisted couplings.
Always follow the vehicle manufacturer's bodybuilding instructions.
