General information
Features and applications
The wire rope isolators AVC comprise two pairs of bars, joined together by a connecting cable with a helical winding (coil).
They are generally used for isolating vibrations and shock absorption, where axial holding force, resistance to compression and shear force is required.
Vibrations can cause:
- malfunctioning and reduction of the machine lifespan and/or of the adjacent ones;
- damage to health;
- noise.
They are particularly suitable for use with HVAC, pumps, purification and desalination plants, instrumentation panels, rail, naval and military. Some examples of application are shown in Fig.1.

The min. load is the value below which the vibration damper is not able to isolate the vibrations as it would be too rigid.
The max load is the value beyond which some type of failure may occur that compromises the functionality of the vibration damper.
The min.deflection is the crushing of the vibration-damping support corresponding to the min. load.
The max.deflection is the crushing of the vibration-damping support corresponding to the max. load.
