▶The Concrete pipe testing machines are consisting of a frame and a hydraulic power pack. The frames are rigid 2 column constructions with superior axial and lateral stiffness and are precision aligned. Integrated in the crosshead is a double acting actuator in servo-quality. The actuator has antirotation system to prevent the natural tendency of the actuator to rotate. The stroke of the double acting actuator is300 mm. Load cell is used for precise load measurement and closed loop control.
