Servohydraulic vertical dynamic axial torsion testing machines of the H.8 series are used to perform torsional oscillating or tensile / torsional tests of test samples or whole products in the engineering, pharmaceutical, construction and automotive industries, including academic institutions. These machines have an axial / torsional test drive mounted on the upper cross member. The optional base plate with T-slots in the crossbar makes these machines very versatile. • Stand design with high axial and torsion rigidity and mechanical resistance. • Possibility of extending the test frame by automatic electro-hydraulic transfer and clamping of the crossbar. • Guaranteed system coaxiality in accordance with ASTM E 1012. • Integrated servo cylinder in center crossbar of the machine. • Torsion induced hydraulically or electromechanically depending on frequency and number of cycles. • Test control by proportional or servo valve with the possibility of control in the power and position loop. • Complete test evaluation and control is provided by Test & Motion material testing software – DYNPACK. • Combined torsion load cells located on the piston rod operating in the accuracy class according to EN ISO 7500-1, ASTM E4 with the possibility of linearization. • Powerful compact hydraulic units of the HAD series with low noise level thanks to the PAC system. • HALT 18 hydraulic unit diagnostics controlled by TOUCH LCD SIEMENS as standard. • The H.8 series machines comply with all the above-mentioned EC directives on machinery and equipment and work in accordance with the new safety functions according to EN ISO 13850-SIL 1/PL.
