I. Product Introduction

The computer-controlled rail static bending testing machine is a specialized device for static bending tests of welded rails. It is used to conduct static bending tests on flash-welded rails, thermite-welded rails, and gas pressure-welded rails for railway applications, testing mechanical properties such as the maximum load capacity, failure test force, and deflection deformation of rail welded joints.
