The challenges of suspension systems
The demands placed on today's mobile machines are constantly growing, and so are the demands placed on suspension systems. Manufacturers' and customers' wishes and legal requirements also lead to new challenges, with the focus remaining on driving safety, comfort and durability. There are also functions such as load-independent levelling, driving status-dependent driving behaviour, adjustable driving comfort and suspension locking. To reduce wear, machine downtimes and service costs and to protect the increasing number of sensitive electronic components in machines, it's also important to significantly reduce mechanical component loads. Hydropneumatic suspension systems achieve these functions and offer a suitable solution to the aforementioned challenges.

By decoupling the vibration excitations from the road surface to the vehicle chassis, hydropneumatic suspension systems help to improve driving comfort and driving safety. The customer benefits from this, as the improvement in their machine's driving performance is noticeable in daily use. Our customer satisfaction is our motivation and drives us forward every day.

Axle suspensionFor increased driving stability
Axle suspension systems need to be tailored to the machine and the customer's functional requirements. Both individual axles and systems in which all vehicle axles are fitted with suspension can be implemented. In the latter case, this is referred to as full suspension. To achieve the desired performance setup and an optimum combination of driving safety and driving comfort, we combine the right components for your particular hydropneumatic axle suspension system.
Cab suspensionFor increased driving comfort
Cab suspensions decouple the driver cab from the vehicle chassis and minimise vertical accelerations for the driver. Both partial and full load-bearing hydropneumatic suspensions can be designed to meet specific machine requirements. Depending on the design, cab rolling and pitching movements can also be reduced, which provides additional comfort. With HYDAC suspension struts (FDE), we offer you a system solution that combines suspension cylinders, travel measurement technology, spring accumulators and valve technology in an extremely compact way. This saves installation space and installation costs.
Boom suspensionFor optimum component protection
Hydropneumatic boom suspensions make a significant contribution to improving the driving behaviour and driving comfort of mobile machines with masts. By installing the HYDAC hoisting gear stabilisation units (HSE), vehicle chassis excitations caused by uneven ground are decoupled from the hoisting gear during driving. For this purpose, the piston chamber(s) of the lifting cylinder(s) is (are) connected to the HSE, which combines valve technology and piston accumulators in a compact design. This "hydropneumatic spring" also reduces mechanical and hydraulic component loads. Our hydropneumatic boom suspension system is available in various sizes and designs to suit your machine.
