The Hendrickson Hydro-Pneumatic (HHP) suspension provides severe off-road vehicles with superior ride quality, handling, stability and durability with low maintenance requirements.
- Use of hydraulic spring cylinders combined with advanced hydraulic piston accumulators reduces vibration and harshness to chassis and body equipment, providing smooth ride and extending life of vehicle
- Proven in a variety of demanding defense applications to provide premium performance and rugged durability
- Hydraulic valves provide controlled, load-dependent damping for superior ride quality in demanding load conditions
- Cross-plumbing between spring cylinders provides high stability and handling characteristics to accommodate uneven terrain, NATO double lane changes and evasive maneuvers
- Advanced triple chamber piston accumulators provide low spring rate regardless of load conditions, and equalize load to help provide continuous tire contact with the ground for increased traction
- System provides raising and lowering capability, and ability to achieve multiple ride heights
- Optional blocking system automatically locks ride height in situations where movement of vehicle platform is not desired, such as loading, unloading, towing or satellite communications
- Power only used to level vehicle due to changes in load; no power/fuel consumption while vehicle is in motion due to closed system
- Adaptable to multiple axle combinations and load range requirements
