Two new Demag crane models featuring MTU engines from Rolls-Royce

  • The AC 300-6, 78 meters high, with 6R 1500/OM 473 engines
  • Compact AC 45 City crane with 6R 1000/OM 936 engines
  • MTU engines now powering 13 Terex and Demag crane models

FRIEDRICHSHAFEN – Rolls-Royce is to supply MTU engines to equipment manufacturer Terex Cranes for two new Demag models. The Demag AC 300-6 will be powered by a Series 6R 1500/OM 473 engine, and the AC 45 City crane by 6R 1000/OM 936 engines.

MTU and Terex Cranes have a long history together, with MTU supplying engines for nine mobile crane models and four crawler cranes down the years. The successful partnership with MTU is now to be continued for the company’s current range of cranes.

Dr. Aaron Haußmann, Head of Construction and Agriculture Sales at MTU, said: “MTU leads the pack when it comes to drive systems for large mobile cranes. As well as Terex Cranes, numerous other big-name construction equipment manufacturers such as Tadano and Manitowoc also source many hundreds of Series 1000 to 1500 engines per year from us.”

The two new Terex Cranes models are all-terrain cranes, able to move on or off-road, making them ideal for building telecomm towers and overhead cable masts, power stations and container terminals as well as for use in rescue and recovery operations, and for revision and testing activities.

Up to 78 meters high: the Demag AC 300-6 crane
With its 80-meter arm fully extended, the Demag AC 300-6 crane can lift weights of up to 15 metric tons to a height of 78 meters. The all-terrain crane is therefore mainly used as an auxiliary crane for erecting rotating tower cranes. With a vehicle base just 15.3 meters in length and 3 meters wide, its compact dimensions mean it can be adapted to suit a wide variety of tasks. The 6R 1500/OM 473 engines are able to produce up to 430 kW of power, and their exhaust gas aftertreatment systems such as SCR and cooled exhaust gas recirculation (EGR) ensure they meet the requirements of the current ‘EPA Tier 4 final’ emissions directive.

Nimble and compact: the Demag AC 45 City crane
The AC 45 City crane, which was presented last October, has convincing features which include a compact design combining a single cabin for both driving and crane operation with high power performance. 8.69 meters long, 2.55 meters wide and 3.16 meters tall, its modest dimensions make the Demag AC 45 City one of the most compact cranes in its class. The extremely small, nimble vehicle has been designed specifically for use in towns and cities, and therefore requires a compact engine featuring high power density. The answer is a six-cylinder Series 1000/OM 936 which provides the Demag AC 45 City with up to 260 kW of power.

Because the 7.8-meter-long chassis housing of the main boom is also very compact, the AC 45 City is able to work inside fairly low bays while lifting heavy loads.

The MTU Series 1000 to 1500 engines have been developed specially for industrial applications in the agriculture and construction sectors and are based on Daimler commercial vehicle engines.
