Dynostar Model 4T

A UNIQUE DYNAMOMETER

With this unique and multifunctional dynamometer, you are able to test three different types of vehicles: carts, ATV’s and motorbikes. All Dynostar Model 4T dynamometers are fitted with electrically adjustable wheel clamps. The wheel clamps are designed to make sure even wide quad tires can be clamped without any problems. 

Because the dynamometer is fitted with a roller with a high mass inertia it is suitable for dynamic power up to 440 kW. 
With a powerful air-cooled retarder this dynamometer can absorb power up to 355 kW (with a cold eddy current brake). To save space, the eddy current brake of this Model is integrated in the roller. To cool the eddy current brake, Dynostar has applied the principle of forced cooling. A centrifugal fan presses air through the heart of the roller, this way the retarder is force-cooled. 

The roller-brake combination is mounted on one shaft, which results in a dynamometer which is totally free from vibrations.
