Long Stroke Thrusters
Seismic Test Systems - Unholtz-Dickie Corporation (UD)
Unholtz-Dickie offers the world’s first all air-cooled, electrodynamic long-stroke testers for telecommunications, earthquake simulation, and transportation applications. Up to 2,300 lbs (1,040 kg) of payload can be supported on a 48x48 inch (1.2 x 1.2 m) footprint on either the slip plate of the horizontal LS12H thruster or the bearing-guided head expander of the vertical LS12V unit. Both are driven by the highly reliable SAI120 SiC amplifier with an integrated switching cabinet for either vertical or horizontal testing. And because it’s an electrodynamic shaker, relatively high frequencies of up to 1,000 Hz can be achieved.
