Static And Dynamic Steel Rail Test Machine
Product Description
The first domestic three-station sleeper fatigue tester, with the ability to test fatigue life at the same time of three samples per group, greatly improves the detection efficiency and reduces the operating cost. It adopts a 3-station self-reactive force integrated loading frame, which has a compact structure and a small footprint. This model is developed according to the technical requirements and design concepts put forward by the railway construction inspection station. It has been operating continuously and reliably for a long time in the China Academy of Railway Sciences. It is now a CRCC general fatigue testing equipment.
It is mainly used for testing the mechanical properties and fatigue life of large components and building structures. The machine is equipped with corresponding test loading attachments to achieve typical concrete or steel structures such as beams, columns, plates, frames, sleepers, rails and their welded joints, bridges (full-scale), steel trusses, rubber bearings, railway fasteners Static loading of assembly, steel wire anchors, cables, large deformed springs, slings, rigging, ring joints, automobile chassis, automobile front and rear axles, locomotive bogies, large-diameter precision-rolled rebar, highway pavement structures, etc. Dynamic load performance test and fatigue life test.
