Trampoline pressure testing machine

Trampoline pressure testing machine CX-7302 a Test principle: This device is based on EN913 Annex B, ASTM F381 clause6.6 standards, by applying a static load loading pad on the outer edge of the trampoline and trampoline center position and maintain a certain time frame, to check the trampoline as a whole and components are obvious rupture and deformation. Second, according to the standard: EN 913 Annex B & EN 13219 clause5.3and5.4.2 ASTM F381 clause6.6 Third, the test device: This device as a whole rack of gantry form, size L6000 * W1700 * H3800; an intermediate position in the door frame beams fixed vertical force loading means loading force by the motor drive rod load, load 1000KG end screw fitted pressure sensor connected to the other end of the sensor load pads, trampoline for different heights, you can adjust the height of the force loading mechanism, adjust when by another screw drive mechanism to adjust. Four, test methods and steps: 1) load the trampoline at the loading position of the test pad is placed directly below, while the fixed leg trampoline prevent moving; 2) to adjust the height of the force loading means, means for urging the drive motor, loading pad to move down on the trampoline load static load; 3) loading pad down rate was adjusted to not more than 0.5ft / s; 4) After loading force to achieve and maintain load 65S; 5) loading pad shift, from the trampoline surface, check trampoline for damage; 6) Check the position of the next test, when the loaded position changed by changing the position of the trampoline to achieve. Fifth, the main technical parameters:
