Main features
  • High flexibility universal flexural frame, 300 kN cap.
  • C-shaped open structure for easy specimen loading, closed for testing by a vertical rod hydraulically clamped.
  • Load measurement by high precision load cell
  • Large testing space for a wide range of accessories for conventional and tests under control of displacement and strain rate.
  • For connection to suitable control consoles (eg. 50-C9842 ADVANTEST 9)
General description
General description
UNIFLEX 300 flexural frame has been designed to satisfy the stringent requirements prescribed by the standards concerning, above all, the determination of deformability and ductility index of sprayed concrete and fiber reinforced concrete. The “C” shaped open structure allows an easy and practical front loading but, once the specimen is in the loading position, the structure is closed by a vertical rod hydraulically clamped and controlled assuring high rigidity.
Fitted with high precision strain gauge load cell for  accurate and reliable test results. The frame has to be connected to a control console and completed with the suitable testing accessories depending on the test to be performed. The tests under control of displacement and strain rate can only be performed with the ADVANTEST 9, Servo-hydraulic control console or MCC, multifunctional control console
