CTW Automation ~ Damper & Shock "Dyno" Testing Equipment

Mission Statement:
CTW Automation grew out of the ashes of what was Roehrig Engineering. We built the industry standard shock testing equipment for the racing community and then provided the best customer support on the planet. Now, with all ex-Roehrig employees we are building a new generation of testing equipment to fit your needs and exacting requirements. We make a wide variety of crank type machines as well as a broad range of electric linear actuators capable of high force, high velocities and very high frequency response.

We are fully capable of servicing all types of damper and spring testing equipment and will be quickly ready to upgrade your software as well to the next generation of CTW Shock Testing and Control Software.
