Truck and car speed tester

Products > Test lanes

The tester has the function of measuring the actual speed of the vehicle and compare the value shown by the speedometer and the actual value. 
The speed tester chassis consists on:
- a metal frame that supports 4 rollers
- a braking and lifting device
- a pneumatic system that activates the lifting device. 
The two pair of rollers are rigidly attached to the special transmission shaft in order to ensure equal speed of both wheels tested in the same axle. The rollers are in neutral position, they do not have braking or inertial load counteracting the axle force of the tested vehicle. 
The rollers are rectified and balanced to ensure regularity of the test in absence of vibrations.
