Improved Flexible Coupling For Trucks

-The Improved Flexible Coupling has smaller inertia and better damping ratio.

-Improves lifetime of the power train components.


Sandvik has released a new Flexible Coupling for Sandvik TH551, TH551i, TH663 and TH663i dump trucks.

New improved flexible coupling has smaller inertia value and better damping ration compared to old flexible coupling.

This improvement, associated with the Improved Up-Box (see previous page), will help to reduce the torsional vibration in the rest of the power train, which improves the lifetime of the power train components.

This modification is only possible on Volvo powered trucks.
