Arocs

Frame, chassis, suspension

Loading capacity and robustness are standard equipment on the Arocs.

Loading capacity and robustness are standard equipment on the Arocs. In the design. For the material. And for 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 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
  • Two different application specific frames for construction site/off-road use and for road use, with different frame tracks of 744 mm and 834 mm and longitudinal members in three thicknesses of 7 mm, 8 mm and 9 mm
  • 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 resulting from increased frame height plus front and rear axles with varying offsets through to a straight axle

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.

Steel suspension. The steel suspension on the Arocs performs well in every situation 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 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.

The axle load compensation between the front axles prevents overloading damage on 8x6 and 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.
