Underrun protection
2022
General information
General information
The components used to connect a vehicle and trailer are exposed, even during normal use, to very high tensions. Regular service and maintenance is a prerequisite if the mechanism for the underrun protection is to function well for the duration of its service life.
The length of the service intervals depends on usage, roads 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 function limits have been exceeded or that the function of the product has been impaired, servicing must be carried out immediately.
None of the product's wear limits having been exceeded indicates 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 underrun protection has been damaged due to e.g. jackknifing, off-road driving,
reversing or collision, the underrun protection with attachment parts must be replaced.
Always follow the vehicle manufacturer's bodybuilding instructions.
