Sisu launches 220-ton prime mover


Recommended Posts

Auto Review  /  May 10, 2016

Finland-based truckmaker Sisu (http://eng.sisuauto.com/) abandoned the mainstream truck market several years ago to focus on specialty applications including logging and dump trucks.

A particularly interesting new model is Sisu’s Polar CK16M twin-steer 8x4 heavy haul tractor for carrying oversized loads.

Until now, such tractors were built only by the major European truckmakers.

The CK16M is designed for a gross combination weight of 220 metric tons (485,017 lb).

The new Sisu utilizes a Mercedes-Benz Arocs cab purchased through a supply agreement.

The truck’s OM473 (aka. DD16) engine is rated at 625 horsepower and meets Euro-6 emissions standards.

Unusual for Europe, the OM473 is paired with an American Eaton Fuller RTLO22918B manual transmission with a 2-disc clutch. Sisu has a long tradition is using American transmissions boxes since the early 1970s, and for many years used Caterpillar engines.
