Dual channel bridge shell fatigue testing machine

1Dual channel bridge shell fatigue testing machineIntroduction

Mainly used for conducting dynamic and static performance and fatigue tests on the axle shells of construction machinery and heavy vehicles. After configuring corresponding test attachments, it can also be used for dynamic and static performance testing, fatigue testing, and life testing of various components, building materials, and large parts. This equipment generally adopts a two channel coordinated loading test system, mainly composed of a large base plate, gantry, actuator, pump station, control system, accessories, hydraulic pipelines, etc.
