Bending testing machine 300kN


The bending testing machine is suitable for bending tensile strength tests of various steel fibre concretes, concrete beams and shotcrete. A position measuring system is installed in the cylinder by default. The massive steel frame is extremely stiff, the columns are tensioned without any play. High accuracy class 1 according to DIN EN 7500-1 in a very wide measuring range.

Norms: DIN EN 12390-5, 1339, 1340, ASTM C78, C293, C469, C496, C1019, C109/C109M

Control Unit

Doli EDC provides fully automated experimental procedures with predetermined rate of loading, force controlled tests (deformation and displacement controlled tests require further accessories), automatic break detection.


A large area of the testing machine can be equipped optionally with an impact-resistant, transparent test room protection made of polycarbonate.
