FT300 Tests

FT300 has stationary parts, provided with grips for holding one end of each of the test pieces in a fixed position, and similar but reciprocating parts for holding the other end of each of the test pieces. The travel of the up and low grips can be adjusted to fit different tests. FT300 use two equal groups for testing, so that one group is being flexed while the other group is being straightened, thus reduce the vibration in the machine.
