nigeria LHSL-326E Expansion Joint Rubber Seal Strip Clamping Performance Testing Machine
Product Description
The microcomputer-controlled electronic tensile testing machine, specifically designed by Beijing Lanhang Zhongke Measurement and Control Technology Research Institute, is for rubber sealing strips in highway bridge expansion joints. The computer system controls a high-precision stepping motor through a full-digital controller and a speed control system. After deceleration by the deceleration system, it drives the movement of the moving beam through a precision ball screw pair to complete the repeated tensile mechanical performance test of the sample. It is suitable for the performance testing of rubber sealing strips in highway bridges and other applications. The equipment complies with the standard requirements of JT/T326-2016 "General Technical Conditions for Highway Bridge Expansion Joints".
