EHF-U Series

Servo-Hydraulic Testing Machine (Servopulser)
U-Type Loading Frame (Overhead Actuator Type)

For Endurance Testing and Functional Testing of Actual Specimens

The large testing table below and crosshead mounted actuator above create a large testing space for testing actual objects, such as structural members and large specimens.

[Features]

The spacious testing space accommodates 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.
The one-touch crosshead hydraulic drive mechanism allowed the crosshead to be raised or lowered and clamp operation to be performed easily by a single handle.
