ELE Dynamic Electromechanical Triaxial Testing System is a triaxial system, based on an axially-stiff load frame with a beam mounted electro- mechanical actuator. It has been designed to fulfil the demand within the geotechnical laboratory testing industry for a lower cost, more basic dynamic triaxial testing system
This system superseded systems using pneumatic actuators in terms of life costs and overall usable performance. Electro-mechanical systems can carry out full load dynamic testing to the stated frequency. Electro-mechanical systems are environmentally friendly as they only draw the energy required to do the test, resulting in lower life costs. Electro- mechanical systems are also safer to run due to no high pressure air or hydraulic pipelines being required.
Triaxial Cell
• Conforms to IS:2720 (Part 11) & (Part 12) standards.
