First MTU Engines from Rolls-Royce for KATO Excavators

For the first time, Rolls-Royce is supplying MTU-brand engines to Japanese construction machinery manufacturer KATO for use in its excavator segment.

The engine, a 6-cylinder inline Series 1000 unit delivering 280 hp, will be used to power a 30 t hydraulic excavator from KATO’s HD range. Equipped with an SCR system, the MTU engine meets the specifications of Heisei 26 – the emissions stage in effect in Japan since last year. The MTU brand is part of Rolls-Royce Power Systems.

“We were very impressed by the performance of MTU engines in our rough-terrain lifting cranes, so with our eye on the Heisei 26 emissions standard, we’re again choosing renowned drive technology from MTU for our new excavator,” said Mitsuo Okada, director & executive officer from KATO.

“Japan is a high-tech country where we already have our MTU engines in service in wheel-loaders and cranes. Now we’re delighted to consolidate our successful partnership with KATO by entering the Japanese excavator market too,” said Bernd Krüper, vice president of Industrial Business at MTU.

The hydraulic excavator in question is destined for off-highway service, and the engines powering it must be capable of adapting quickly to unpredictable changes in load imposition. Meeting the special demands of the excavator on the engine dynamics demanded a high level of technological input.
