Mercedes-Benz Arocs

• Specialist for on- and off-road operations

• Hydraulic Auxiliary Drive: start assist at the push of a button

• Wide choice of cabs and axles

The Arocs is one of the Mercedes-Benz truck models specially developed for tough conditions. This model is suitable for demanding off-road tasks both in winter and road maintenance service, and can also be adapted to suit customer needs as a roll-off container truck/skip loader.

The economical BlueTec 6 engines are available in 16 different output ratings ranging from 175 kW (238 hp) to 460 kW (625 hp).The four displacement variants ranging from 7.7 l through 10.7 l and 12.8 l to the new top capacity of 15.6 l in the new OM 473 generate maximum torque of 1000 Nm to 3000 Nm.

As standard, the engine power on the Arocs is transmitted by automated Mercedes PowerShift 3 transmissions. Different drive programmes have been specially developed and can be implemented according to the vehicle's application. The available drive configurations range from the 4x2 two-axle vehicle with rear-wheel drive to the 8x8 and 8x8/4, a four-axle truck with all-wheel drive and two steered front axles.

Seven cabs are available in 14 variants. Apart from the product group "Loader", there is also a "Grounder" Arocs group. The Loader exploits the available weight-saving potential to the full. In contrast, the stable and robust Grounder is designed for assignments in tough conditions.

Hydraulic Auxiliary Drive: start assist at the push of a button

Mercedes-Benz supplies the Arocs without all-wheel drive for predominant use on the road and in mild terrain, and with selectable all-wheel drive for terrain of medium difficulty and with permanent all-wheel drive for heavy-duty off-road use. The Arocs with Hydraulic Auxiliary Drive (HAD) now rounds out the product line-up as another variant. The term describes a hydraulic auxiliary drive for the front wheels for occasional off-road use.

The practical advantages: While payload is paramount for classic construction site vehicles with bulk cargo, loading and unloading requires high traction. Roll-on/roll-off tippers require a traction aid when unloading on unpaved or slippery ground. This is especially true when the truck is also used for winter road maintenance during the cold months.

The operation of Hydraulic Auxiliary Drive is quite simple for the driver: all it takes is a push of a button in the cockpit and the auxiliary drive is active. This can be done while still on the road before entering the construction site, or at any time in off-road terrain.

Like the Actros and Antos, the Mercedes-Benz Arocs can be equipped with a turbo-retarder clutch (TRC) which allows wear-free starting and a high braking performance. At the same time it reduces fuel consumption and CO₂ emissions.

Lowered cab

Four-axle chassis with an engine tunnel height of 320 mm instead of 170 mm are new in the Arocs series. The correspondingly lowered cab offers the advantage of a lower overall height for dump trucks. It is generally easier to climb in thanks to a smaller distance between the steps.

Also new is a further extended offering of drive axles: The three-axle versions with two driven rear axles are now all also available both with a permissible axle load of 2x10 t (26 t GVW) and 2x13 t (33 t GVW) from 310 kW (421 hp).

Show exhibits

On the stand in the hall, Mercedes-Benz is showing an Arocs 1835 LK 4x2 with a tipper chassis, the road-sweeper body of which was manufactured by Faun. This is incidentally the first ex factory Arocs to feature the space-saving "Sweeper Pack", which was specially designed for compact road-sweepers with a short wheelbase.

An Arocs 2743 AK 6x4/4 with a steerable, lifting trailing axle and an Arocs 2036 AK 4x4 are on display in the outside area. In the first case the body is by Meiller Tippers and Hiab Cranes, while the second Arocs is a winter service vehicle from Charter Way with a body by Aebi Schmidt.
