ENGINEERING AND ENVIRONMENT TESTS

Hydraulic tests facilities

Test Means

5 Hydraulic Generators are available to carry out tests in the low frequency range. These test facilities allow the simulation of marine vibrations conditions. They have proven their efficiency in such fields as road (HGV), rail transportation or seismic vibrations.

Special characteristic of the 150 kN generator

The test chamber of the 150 kN generator complies with pyrotechnic test standards and is equipped with a dia. 2 m. horizontal table fitted with a pneumatic load compensation device.
