Loading capacity and robustness are standard equipment on the Arocs. In the design. For the material. And for the frame, chassis and suspension.

Frame, chassis, suspension
Loading capacity and robustness are standard equipment on the Arocs.
A strong foundation to build on.
Construction-site and on-road use impose different requirements on the frame. That's why we have developed two for the Arocs. One with a narrow frame track of 744 mm, which boasts high torsional flexibility and stability even under extreme off-road conditions and one with a wide 834 mm frame track, which comes into its own in on-road use while also performing convincingly in light off-road use.
Advantages at a glance.
- Robust and durable steel suspension for high load capacity and resilience in heavy-duty construction site operations
- 4-bellows air suspension121 for optimised driving dynamics and ride comfort in primarily road-based operations
- Different, application-specific frames for use both on construction sites or off-road, as well as on the road
- 8x6 and 8x8 vehicles with axle load compensation for reduced wear and better handling in off-road use
- Electronic brake system with integrated auxiliary brake function, drum and/or disc brakes, hill holder
- Various application specific all-wheel-drive variants and Hydraulic Auxiliary Drive135 for maximum traction on tap when high payloads are involved
- High ground clearance
Suspension variants.
Robust steel suspension or a combination of steel suspension and air suspension – the Arocs has the right solution according to the intended application.
A robust, durable steel suspension provides good load capacity and high suspension comfort in construction site use.
Axles.
On-road, off-road or at the construction site – the axles on the Arocs are impressive performers everywhere. Depending on the type of application and chassis, various front axles with a permissible front axle load of up to 9 t are available. For road use, the Arocs is fitted with hypoid drive axles with a load capacity of up to 13 t. The planetary axle with a load capacity of up to 16 t comes into its own at the construction site.
Full braking power.
Depending on the intended application, drum brakes, a combination of disc and drum brakes or disc brakes ensure short stopping distances for the Arocs. For increased safety, the complex braking and traction functions of the entire integrated structure are controlled via the electronic brake system with anti-lock system and acceleration skid control.
All-wheel-drive range.
Two all-wheel-drive variants are available for outstanding traction: permanent all-wheel drive with low-range gear and disengageable all-wheel drive. For the majority of its work which entails demanding manoeuvres in difficult terrain, such as moving off on gradients on unsurfaced terrain, the Arocs is equipped with permanent all-wheel drive.
When high payloads and low fuel consumption are required, the engageable all-wheel drive is available.
Hydraulic Auxiliary Drive135.
The Hydraulic Auxiliary Drive is available for operations geared towards road use which occasionally need high traction on tap.
The starting-off aid is suitable for all operations which require maximum torque at short notice but also demand a high payload and an optimum drivetrain.
Ground clearance.
Different types of deployment call for different degrees of ground clearance. Tractor unit, concrete mixer or tipper – the Arocs meets practically all requirements.
All Arocs trucks go into operation with a higher frame, resulting in greater ground clearance. All-wheel-drive tippers perform impressively even in difficult terrain, with their large ground clearance. Arocs tractor units offer sufficient ground clearance to enter construction sites without incurring any damage. For an optimised approach/departure angle, the Arocs features shorter frame overhangs.
Axle load compensation.
The axle load compensation between the front axles prevents overloading damage on 8x6 and 8x8 vehicles.
