产品简介

Architectural engineering of this machine is mainly suitable for steel pipe nominal diameter of 48.3 mm and 51 mm scaffolding, derrick and templates support the use of malleable cast iron or cast steel fasteners made of the tensile properties, compressive properties, anti-sliding performance and damage resistance and performance test for mechanical properties of torsional rigidity.At the end of the test, the test parameters are automatically analyzed and processed by the software according to the test parameters set at the beginning of the test, and the test results are automatically saved.The test parameters can be checked and printed after the test, and the software has flexible and diverse control methods, and the test software is upgraded for free.
