PURPOSE:To expand the testable range of one testing machine largely, by supporting supporting posts by supporting shafts, which cross said supporting posts on body brackets, and constituting the supporting posts so that they can be inverted by 180 deg. with respect to the body brackets with said supporting shafts as the centers. CONSTITUTION:The entire bodies of supporting posts 1 and 1 are lifted upward together with supporting shafts 8 and 8 by an actuating means 15 with respect to upper and lower parts 9a and 9b of body brackets 9. Legs 1b and 1b or 1a and 1a are separated upward from a body bed 10. Thereafter, both supporting posts 1 and 1 are inverted with the supporting shafts 8 and 8 as the centers. By this inversion, the position of an upper frame 2 and the position of a lower frame 3 can be inverted. Therefore, the position of an actuator 5 can be changed to either of the upper position or the lower position from a material under test 4. |
