One of the most essential qualifications for a construction truck is high ground clearance. That’s why we created the air suspension GRAS-G2 for up to three rear axles. At the same time we created outstanding stability and driving comfort, whether the truck is laden or unladen. This is a rear suspension that is specifically developed for the gravel pit. And now it’s available for the Volvo FH series.
Better Traction and higher avarage speed.
Optimised rear-axle pressure on every axle means better traction, thanks to the air suspension. The driver can adjust axle load distribution for better traction if needed. Air suspension gives less vibration into the truck and you will get an improved driving comfort, especially when unloaded. This will also contribute to a higher average speed.
Stabiliser in bogie centre.
The position of the stabiliser bar results in less torsion forces on the chassis and better roll and tipping stability. It also contributes to the high ground clearance.
Air bellows mounted above the axle.
The air bellows are more protected and their new positions contribute to the high ground clearance. As do all other components.
Air suspension provides outstanding driving comfort and makes it possible to vary the ground clearance. No parts of the suspension lay outside the rear tire envelope. This makes it easier to adapt the chassis for applications such as asphalt layers or tippers.
Don’t worry. No parts of the braking system stick out beneath the rear axle. That’s why you can be sure that the truck can handle all obstacles.
