Channel Fatigue Testing Machine

The electro-hydraulic servo embedded channel fatigue testing machine utilizes electro-hydraulic servo control technology and is primarily used for fatigue life testing of embedded channels in electrified railway catenary tunnels, fatigue characteristic testing of the channel body, and fatigue characteristic testing of the integrated prefabricated assembly of channels, anchor rods, and T-bolts. It complies with standards such as TB/T3329-2013 "Embedded Channels in Electrified Railway Catenary Tunnels" and TB/T "Test Methods for Components of Electrified Railway Catenary Systems."
