LGWY-5000J Computer control Electro-Hydraulic Servo Compression Shear Testing Machine

Compression Shear Testing Machine

Introduction

LGWY-5000J microcomputer controlled electro-hydraulic servo compression shear test machine adopts cylinder under-type and four-column structure. The frame has high rigidity and small deformation, and meets the requirements for testing of road and railway bridge plates type, pot type and spherical bearings. The test space is steplessly adjustable to facilitate test requirements at different heights. It adopts independent research and development and proprietary multi-channel closed-loop coordinated loading electro-hydraulic servo control system. Microcomputer control coordinated multi-stage hydraulic loading, continuous loading, stable multi-level test force retention, automatic load retention, automatic acquisition and storage of data, and drawing of curves, Automatically print test reports, the computer controls the test process in a timely manner, displays the test force and test curve, and the operation is simple and reliable.
