This testing machine adopts a frame structure of welded steel plates as a whole, driven by an AC servo motor and a ball screw. The load sensor measures the force, and the tensile space can be adjusted step by step according to the sample size and length. The computer screen displays the test force and test curve, and automatically processes the test data according to the requirements of the test method. This machine is an ideal inspection equipment for coal power enterprises, coal mining machinery equipment, safety production inspection institutes, technical supervision and other industries. It is suitable for testing the tensile load and damage of products such as wires and cables, porcelain bottles, double hooks, steel strands, safety belts, waist ropes, foot buckles, etc. It requires flexible and convenient operation, slow and stable loading, strong body bearing capacity and other advantages

The testing machine adopts a digital AC servo speed control system with high speed regulation accuracy and stable performance, and a motor as the driving system; Specially designed synchronous toothed belt reduction system and ball screw pair drive the movement of the testing machine's moving crossbeam; The control and data processing software based on database technology using Windows as the operating platform adopts virtual instrument technology instead of traditional digital tubes and oscilloscopes, realizing the screen display of test force, peak test force, beam displacement, sample deformation, and test curve. All test operations can be completed on the computer screen by mouse input, with a good human-machine interface and convenient operation; The dual channel fully digital programmable amplifier inserted into the PC realizes true physical zeroing, gain adjustment, and automatic shifting, zeroing, and calibration of test force measurement, without any analog adjustment links. The control circuit is highly integrated, completely eliminating mechanical adjustment devices such as potentiometers, and the structure is simple,.
