Resilience and robustness are defining features of the Arocs. This is demonstrated in the trucks structural design, including the frame, chassis, and suspension.
Arocs
Frame, chassis, suspension
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. The other, 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
- Different, application-specific frames for use both on construction sites or off-road, as well as on the road
- Various application specific all-wheel-drive variants 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. With the weight-optimised parabolic spring assemblies and corresponding matched shock absorbers and stabilisers, you are all set for whatever your operations hold in store. The Arocs for road use is equipped with steel suspension on the front axle and air suspension on the rear axle. In conjunction with the wide frame the 4-bellows air suspension1 helps to deliver excellent road holding and high ride comfort. Minimal noise, gentle transport of loads and simple loading operations for tractor units and rigids are further advantages. The air suspension can optionally also be configured for higher loads.
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 help 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.
Ground clearance.
Different types of deployment call for different degrees of ground clearance. Tractor unit, concrete mixer or tipper – the Arocs meets a wide range of construction requirements.
All Arocs trucks go into operation with a high 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 a hassle. For an optimised approach/departure angle, the Arocs features shorter frame overhangs.
Axle load compensation.
The axle load compensation between the front axles helps to avoid overloading damage on 8x8 vehicles.
