Development
ACUTRONIC is pleased to introduce a new range of Geotechnical Centrifuges Colin Stevens, Vice President Sales, ACUTRONIC Switzerland
ACUTRONIC manufactured geotechnical centrifuges in the 80s and 90s and now intends to continue with a redesigned line for the new millennium.
Users of geotechnical centrifuges are t ypically universities and/or civil engin eering facilities that may be researching building foundations, dams, oil rig foun dations, piles, earthquakes, and more. Their research may include failure modes for any structure or material that is d ependent upon its self weight. These modes can be simulated on a reduced
