evaluated by sensors and sent to the software via the field bus system (Bnet).

Functions
1 + 4
Left test rollers
Transmit their rotating motion via friction to the wheel being tested. The test rollers have a plastic/
corundum coating in the standard version. Due to the very high coefficient of friction, high braking
forces are transmitted even with a low axle load.
Each pair of rollers is driven by an electric motor. Power is transmitted between the test rollers on
each side by way of a chain drive.

Inspection pit
The working pit is below the level of the workshop bay; work on the underside of the vehicle is
carried out here.
2 + 5
Right sensing roller
Monitors the running of the wheel (slip check) and the wheel position and thus implements the
switching and safety function of the tester. A foot guard is provided beneath the slip rollers.
