Application area:
Suitable for testing equipment for static load crack resistance test of concrete sleepers (I pillow, II pillow, III pillow, fork pillow, bridge pillow, wide sleeper, etc.)
System composition:
The use of digital bus technology, microcomputer control, servo hydraulic loading system and other new technologies. Can accurately and quickly detect the static strength of various sleepers, and can test the actual bearing capacity of sleepers. The sleeper static load tester consists of a press, a trolley, a track, a jacking mechanism, a hydraulic system, and an electrical control system. It fully satisfies the technical conditions for the concrete sleeper static load tester developed by the National Academy of Sciences of the Ministry of Railways.
