YJZ-500E High Strength Bolt Tester

Used for axial force inspection of large hexagon high-strength bolt connections, construction torque inspection of bolt connections, torque coefficient re-inspection of bolt connections, pre-tension re-inspection of torsional-shear type high-strength bolt connections, and construction torque inspection of torsional-shear type high-strength bolt connections. The software automatically calculates average axial force, average torque, average torque coefficient, standard deviation, and coefficient of variation, etc. It displays torque coefficients, axial force curves, torque curves, etc., and also has functions such as parameter setting, calibration, data report printing, output, and query.

YH-24 High Strength Bolt Anti-Slip Plate Tightening Machine

It is a special equipment for fastening slip plates during bolt anti-slip tests.

HY-24 Anti-slip Coefficient Tester

Used for testing the anti-slip coefficient of friction surfaces in high-strength bolt connections, high-strength large hexagon head bolt connections, and torsional-shear type high-strength bolt connections.

JB-300B Impact Testing Machine

Used for testing the impact resistance performance of metallic materials under dynamic load in Charpy impact tests (for V-notch and U-notch specimens).

DWC-60 Impact Test Low Temperature Chamber

Used to provide a cooling environment for V-type and U-type metal impact specimens, ensuring that low-temperature impact specimens of metallic materials reach the specified temperature.

LY71-UV Impact Specimen Broaching Machine

Used for the drawing and forming of V-type and U-type specimens for metal impact tests.

XT-50 Impact Specimen Notch Projector

A dedicated optical instrument used to determine whether the V-type and U-type notches of metal impact specimens are qualified.

HR-150A Rockwell Hardness Tester

Used to measure the Rockwell hardness of ferrous metals, non-ferrous metals, hard high-hardness alloy materials, quenched and tempered heat-treated materials, plastics, bakelite, and some other non-metallic materials.
