  • The host employs a four-column frame structure with hydraulic lifting, clamping, and elastic release for crossbeam stability during tests
  • Column surfaces are electroplated with hard chromium for enhanced wear resistance
  • Crossbeam movement is enhanced with HAWE hydraulic components with ultra-high pressure and zero leakage, ensuring reliability
  • Integrated with high-precision LVDT displacement sensors to measure experimental displacement
  • A precision oil filter with 0.003mm filtering accuracy and a dedicated two-stage electro-hydraulic servo valve enhance actuator performance
  • The modular servo linear actuator offers low damping, high response, and a long lifespan
  • A hydraulic buffer zone at the amplitude limit prevents damage from running out of control
  • Supplied with high-precision load sensor is used to measure test loads, with a pre-stressed ring for improved dynamic response
  • Conveniently designed sample clamping, beam movement, and emergency stop button stations enhance usability
  • Utilizes bidirectional clamping for sample coaxiality regardless of thickness changes
  • The piston, made of alloy steel, undergoes high-frequency quenching for durability and wear resistance
