These have been designed by SAMM for installation on light and medium armoured vehicles weighing under 25 tonnes and have been installed on a number of different tracked and wheeled armoured vehicles.

The hydropneumatic suspension element carries out, in the form of a compact linear unit, the elasticity and damping functions of a suspension. The elastic element consists of a gas which is compressed while oil viscosity is used to damp the motions. If required, the unit can perform additional functions such as attitude correction and ground clearance variation.

Different arrangements can be provided to meet specific customer requests, for example, on-arm suspension type for retrofitting to medium tracked vehicles and MacPherson suspension types for 4x4, 6x6 and 8x8 wheeled vehicles.
