Series SDM 500 - 1000 kN

Specially designed for Crushing Tests on Sewer and Drain Pipes, Concrete Pipes, Fittings, Cones a.s.o. according to EN 1916 for Diameters up to 2000 mm or more.

Concrete Pipe Testing Machines

The frames are rigid 2- or 4-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 anti-rotation system to prevent the natural tendency of the actuator to rotate. With either precision pressure transducer or load cell and optionally displacement transducer for force and displacement closed loop control. The rectangular shaped top bearer is detachable from the actuator and the bottom bearer is V-shaped with an included angle of 150°. The system does not permit rotation at horizontal plane of the top bearer but allows it at vertical plane of a minimum value of +-8°. As option 3- and 4-point bending accessories are available. Available with 19” standard control console in connection with servo valve and digital controller DIGICON 2000, PC running building material testing software PROTEUS and printer for fully automatic test procedure in closed loop mode. Optionally available is a manual controlled testing machine in connection with digital readout DIGICON 1000 and manual 19” standard control console.

Drive-in Cart

for easy loading of the pipes with a crane and for the test preparation

The cart can be pushed easily by hand into the testing machine. In the machine, the trolley is automatically lowered on the base of the machine through a hydraulic system controlled at the console. Rolling track according to customer needs, at least 4 meters long. If the machine is not lowered into the floor, the tracks can be mounted on distance blocks to compensate the height difference.
