Concrete sleeper static load testing machine system / SM800 concrete sleeper static load testing machine system

Application

Equipment suitable for testing the static load crack resistance of concrete sleepers (type I sleepers, type II sleepers, type III sleepers, fork sleepers, bridge sleepers, wide sleepers, etc.).

System composition

It adopts new technologies such as digital bus technology, microcomputer program control, servo hydraulic loading system, etc. It can accurately and quickly detect the static load strength of various sleepers and test the actual load-bearing capacity of sleepers. The sleeper static load test machine is mainly composed of a press, a trolley, a track, a lifting mechanism, a hydraulic system, an electrical control system, etc. It fully meets the technical requirements of the concrete sleeper static load test machine formulated by the National Academy of Sciences of the Ministry of Railways.
