AOS. The oscillation suppression system from PALFINGER

Research and development has real meaning for PALFINGER: To ensure the consistent further development of the product range, the company cooperates with numerous research establishments, conducts internal testing and develops new systems and components.

PALFINGER scores a hit with AOS
The challenge: To suppress the oscillations occurring in crane operation to such an extent that precise load positioning is guaranteed.

The solution: Through the AOS facility integrated in the control system the load is positioned very quickly and virtually oscillation-free. Without having to intervene the operator can work precisely, quickly and therefore particularly efficiently.

What does AOS mean?
The abbreviation AOS system stands for Active Oscillation Suppression system. The patented active oscillation suppression system compensates for the shocks and high stress cycles which arise in crane operation. To be able to recognise these oscillations and then calculate them, extensive metrological analyses had to be performed during the research phase. In line with the results a special sensor system was developed and work to integrate this into existing components began. The outcome of this research activity is a further PALFINGER high-tech product: The AOS system.

Advantages of AOS
- Precise crane movements despite heavy loads and large outreaches
- Crane operations are even more efficient and economical
- Prolonged service life for the loading crane

PALFINGER PALTRONIC 50 and AOS
The AOS facility is integrated in the proven PALFINGER PALTRONIC 50 control system and can be switched on and off using the PALFINGER radio remote control. The dynamic oscillations on the crane are enormous especially in the deployment of long-arm cranes, when a fly jib is used or when moving very heavy loads. The AOS system neutralises the vertical oscillations that result from fast movements and sudden load changes. It registers the pressure peaks and processes them in the PALTRONIC 50. The necessary corrective movements in the crane boom elevating cylinder are then initiated by the control valve.
