DFT-TB Dynamic and static fatigue testing machine
Description
This testing machine is applicable for static and dynamic test for the steps and pallets of escalator and moving walks.
With additional clamps and fixtures, this machine can complete the dynamic and static mechanical properties of materials and components, including Tensile, compression, low cycle and high cycle fatigue tests of materials and components.
