The revamp at Mercedes-Benz Trucks of its wide lineup of trucks is moving forward quickly. Catering to construction work, the brand is working on the new Actros for long-distance transport while the Antos is intended for heavy-duty short-radius distribution. Starting in 2013, the Arocs name will be attached to all the trucks and tractor units that have on and off-road applications in the construction sector.
This is the widest vehicle range that the company has ever offered for the highly diversified sector. The new dump trucks, all-wheel drive dump trucks, concrete mixers, tractor units and drop-side chassis vehicles are offered as two, three and four-axle vehicles with 16 output variants, which range from 238 hp to 625 hp. The entire engine lineup was designed to comply with the future Euro VI emissions standard and could be ordered as a Euro VI version.
The BlueTec 6 engines are created as in-line six-cylinder engines with exhaust-gas turbocharger and intercooler to generate outstanding tractive power at slightly higher than the engine's idling speed. The maximum tractive power delivered by the four engine sizes (7.7, 10.7, 12.8 and 15.6 litre) varies from 1,000 to 3,000 Newton metres. The last variant to be cited is totally new and is offered in the form of the new OM 473 engine.
Furthermore, the Arocs will set an example with its drive system. Power is sent via the Mercedes PowerShift 3 automated transmission, which is standard. The available drive programs were developed particularly for the vehicle's diverse range of applications.
The Arocs range has several drive configurations available to it, such as the 4x2 two-axle version with rear-wheel drive to 8x8/4, a four-axle vehicle with all-wheel drive and two steering front axles. Some examples of the broad selection of new Arocs versions straight off the production line are four-axle versions with one front and three rear axles, a wide variety of air-sprung vehicles, or a load-optimized concrete-mixer chassis with single-tired drive tandem.
