Universal machine for tensile-compression tests

This machine is designed with four columns loading frame is overdimensioned to assure high rigidity and stability. The loading piston, double action, is rectified and lapped. The piston is foreseen of an hydraulic maximum and minimum piston stroke’s security device, by avoiding any damage risk due to wrong manipulations of the unit. An hydraulic selector allows to select the tensile or the compression test.

The heads holding the jaws are obtained from only one block of high tungsten steel, while the jaws are hardened over 65
HRC. The “V” autoclamping form allows a quick and practical churking of the specimen.

This machine is utilized to carry out tensile tests on steel reinforced bars from diameter 6 to 25 mm and flat maximun
25×15 mm. These sample measurements are suitable only for traditional reinforcement bars with maximum resistance around 540 Mpa. In case of testing high resistance rebars with maximum resistance of 800/850 Mpa, the maximum diameter is 20 mm and flat is 25×12 mm.

It can also carry out compression tests on concrete cube specimens maximum side 150 mm. and cylinders maximum diameter 160×320 mm.

The machine is supplied with pair of jaw-holders, but without accessoires for the tensile and compression tests, which must be ordered separately .

Maximum compression load: 1500 kN
Power supply: 230 V | 50 Hz | 750 W
Piston’s stroke: 100 mm
Distance between columns: 270 mm
Distance between the jaws: from 300 to 400 mm
