Railway Sleeper Fatigue Testing, Static And Dynamic Rail Sleeper Test Machine

Computer Control Concrete Sleeper Flexure Testing Machine for concrete rail pillows (Type III pillows, fork pillows, bridge pillows, wide rail pillows, etc.) anti-crack degree (bending) test, accurate and fast detection of the strength of various rail pillows, and test the actual carrying capacity of rail pillows. and anti-fatigue capability at different frequency loads. This mobile static design, dynamic test and static test without any hardware changes only need to open different software (to meet static test, oil road using double-valve in-line, fatigue test, two servo valves working at the same time, to meet the requirements of dynamic high flow, static experiments, all the way servo valve work, to meet the static experiment control accuracy requirements. This not only meets the customer's testing requirements, but also saves the customer the cost of a device. ），

The main unit is a frame structure, which is stronger, more stable and more scalable than the four columns, and the bending fatigue test of the rail pillow can be realized with the corresponding components. Complete protective device to ensure that the test sample breaks without foreign splashes during the test.

Test process: rail pillow →medge trolley→ pushed to the test machine →position ruler to adjust the position of the rail pillow→ load center and pressure plate center re-match, set the test procedure, piston rapid → The speed is close to → at the set load speed, constant loading →loading time→ unloading returns to the specified position, (or reloading to crack the rail pillow) to complete the test of the three load surfaces of the rail pillow.
