Free roller set 6WD

The 6 WD free roller set is an innovative system designed for speed testing of 4WD and 6WD commercial vehicles in our universal speedometer VTU N. No civil works are required, eliminating installation costs.

6WD rollers complement the speedometer when performing speed and tachograph tests.

The set consists of two welded steel frames on which the rollers are mounted to allow the vehicle tyre to rotate freely. The frames allow longitudinal displacement of the assembly and can thus be adapted to the full range of wheelbases.

In addition, it incorporates a mechanical interlocking system that restricts the movement of the vehicle's entry, exit and test manoeuvres, as well as complementary ramps that facilitate these manoeuvres.
