3 . Main Parameters :

The machine consists form several parts

1. Tension mechanism , servo motor and the strap pulley architecture , the intensity of the rotation transformed into tension and supplemented force values turn sensor read correctly tension , the action of the closed-loop control of servo motor to achieve a number of pull . Static and cyclic testing . Rally and speed can be set free . Mainly used for 5 , 6 , 13 , 14 , 15 , and 16 test .
2. In addition to this machine is also configured with two groups of electric actuator , respectively , for a group of the vertical apparatus and the horizontal apparatus 1 group , each group independently adjust the speed and thrust . Stroke is 500mm
3. The vertical means of the servo motor can be used for the actuator , the vertical position adjustment , mainly used for the first 11 . 4 , 22 , 23 and 24 of the test ; the maximum pressure is 150 kg .
4. Level device servo motor caused the brake position adjustment of the pieces up and down and left and right mobile and flexible to meet the demand for different test location , is mainly used for 10 , 12 . 3 and 12 . 4 testing . 50 kg maximum thrust , adjustable up and down the range from 500 mm to 1200 mm.
5. the bottom plate of the test machine drilling multiple rows of screw holes for easy installation of different

4 . Attachments and fixed test conditions
