This December 2017, a special unit was delivered for a company testing high atmosphere aeronautical components in partial vacuum chambers.

The E-4600 synchronizing vibratory drive was specially prepared to withstand the lower outside pressure, with stronger sealings and an overall diminished gap where parts rotate.

Driven by a specially sealed hydraulic motor instead of a regular three phase electric drive via a cardanic assembly, the platform on coil springs to which the vibratory drive is attached, will perform different tests at given amplitude and frequencies, simulating the thin atmosphere stress in high altitude aeronautical components.

With a maximum 8.600 (Kg cm) working moment, it means one can vibrate a 10 tons device on springs with a stroke of 8,6 mm, at 875 rpm for example.

E-4600 vibratory cells are used mainly with heavier vibratory equipment, where the natural synchronizing of two counter-rotating single vibratory motors is not given anymore.
