U-Type
Loading Frame
Servohydraulic
Fatigue System (EHF Series)
Description:
The large
testing table below and crosshead-mounted actuator above create a large
testing space for testing construction materials and large
specimens.
Features Include:
- The large testing
space accomodates large specimens and allows the attachment of
various test jigs and environment control devices.
- The highly rigid
frame prevents buckling of specimens and saves losses in hydraulic
energy due to frame deformation.
- Various test jigs can
be attached.
- Major test
applications: testing of automobile parts and frames
