Frame, chassis, suspension

Frame, chassis, suspension

Resilience and robustness are defining features of the Arocs. This is demonstrated in the trucks structural design, including the frame, chassis, and suspension.

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

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.

Steel suspension. The steel suspension on the Arocs performs well in many situations by virtue of its robust, solid structure, high resilience and high load capacity.


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.

The axle load compensation between the front axles helps to avoid overloading damage on 8x8 vehicles.

Torsionally flexible frame. For construction site operations, the Arocs comes with the narrow frame offering good torsional flexibility. This ensures that the high power is transferred to the ground virtually undiminished, even on uneven terrain.
