HCT and HBT series for tension/torsion tests

HCT and HBT series servo-hydraulic testing machines for tension/torsion tests feature a torsion actuator mounted on the upper crosshead. These versions of the HC and HB series can be used for combined tensile, compression and torsion loading; versatility is enhanced by the optional T-slotted platform.
