HCT/HBT Servohydraulic Testing Machine for Determination of Torsional Oscillation (Tension/Torsion)

HCT and HBT series servohydraulic testing machines for determination of torsional oscillation (tension/torsion tests) have a torsion testing actuator mounted on the upper crosshead. The HC and HB series variant can be used for combined tensile, compression and torsion loading. The optional T-slotted platform makes these machines very versatile.
