Elevator wheel fatigue tester
Product description:
Elevator wheel fatigue tester
Load frame
1. The load frame is double columns framework structure, and the servo linear actuator is at the bottom.
2. The crosshead elevating by hydraulic force, pre-tensile stress clamping and hydraulic loosening
guarantee the stability and reliability of the test and meanwhile guarantee the crosshead locked during
non-test status.
3. Shape of the crosshead has the feeling of three
dimensions and looks terrific.
4. Surface of double columns is plated with chrome, which
make it looks good as well as anti-abrasive.
5. Servo linear actuator is at the bottom, in which there is a
LVDT displacement transducer, out of which there is a
servo valve, and equipped with a precise filter and
accumulator to constitute a servo module.
6. Servo valve is the special high response two grades
servo valve, and the frequency curve is as follows.
7. Applied NCA series linear actuator with the features of lower damp, high response, long life and big
clearance design;
8. The seal parts of servo linear actuator adopt the special high –speed seal parts.
9. Equipped with high precious load cell
