dynoKRAFT A380/200-4WD-ML

Single roller 4WD dynamometer

High-end, modular test bench with mechanical link system

Features highlight

  • 630mm [24,8″] rollers
  • 330km/h [205mph]
  • 1250HP / 800HP wheel power
  • mechanical bevel-gear link

The dynoKRAFT A380/200-4WD-ML automotive chassis dynamometer is the absolute leader in the marked for high-end AWD test benches.
It supports longest wheelbase and widest track among all dynamometers currently found on the market.

It’s modular design enables upgrade from A380-2WD over to 4WD and mechanical link in 3 steps.

The mechanical link system was engineered using angular bevel-gear gearboxes and custom cardan shaft. Any axis can be manually disabled using hand-lever. No noisy belts, greasy chains!

The defaults installation type in PIT. The dynamometer is delivered with all required installation material and metal grating for the pit-installation.
Floor-top installation or combination with 4-post is lift available on request.

Roller width of 2200mm allow to test even wide-body GT race cars without problems.
Wheelbase range: 2200-3300mm (true wheelbase – without need to use roller tangent)

With two 3820Nm and 2000Nm eddy current brakes the A380-2WD automotive chassis dynamometer allows to test up to 1250HP and 800HP  (rear and front wheel horsepower).
All retarders are constantly cooled by built-in fans.

The roller diameter of 630mm reduces tire wear drastically and help keeping the tire temperature under control during long test sessions.

The dynamometer comes equipped with pneumatically actuated wheel-bumper that supports the vehicle during setup.
An built-in LED underbody illumination provides clear view during vehicle strapping.

The dynoKRAFT A380/200-4WD-ML can be freely configured with extension modules (additional inputs, OBD Interface etc…) to match customer needs thanks to our upgradable design concept.
