This machine has been specifically designed to suit the requirements of Central and Commercial laboratories of the construction industry and Civil engineering in general. This universal tester, in fact, can be used for tensile tests on steel re-bars up to 40 mm dia., flats up to 35x75 mm, and compression tests on standard concrete specimens. It can also be used, with the appropriate accessory, for transverse and bending test on steel, flexural tests on concrete beams and general compression tests. Specialò accessories are also available for testing steel strands and electro-welded steel screen.
All the control functions are managed from a standard keyboard and mouse. The frame differ substantially from the old traditional models because of the originality of the design as for example the remote control displacements and gripping systems. The software include a complete suite of programs: tensile, bending, flexure and compression tests. Once the specimen has been placed in the machine (using accessories if required) and the specimen data introduced, the test is run completely automatically at the press of a button up to the printout of the test certificate and the storage of the test data.
Machine frame, cylinder assembly, load cell
Steel base with rigid frame housing the lower grippers
Piston/Cylinder assembly mounted on the top of the rigid frame. Load cell incorporated in the piston
