The testing machine adopts an integral steel welded frame structure with a single rod and double acting piston cylinder to apply the test force, high-strength bolts are used to connect the tested piece, and tension and compression two-way sensors are used to measure the force. According to the specification and length of the test piece, the tension space can be adjusted step by step.

The computer screen controls and displays the test force and test curve, and automatically processes the test data according to the requirements of the test method. The machine is a frame structure beam type, chain type Lifting belts and ropes are special equipment for product by product tensile test, which is used for tensile load, damage and other tests of single structural beam of steel structural frame. It has the advantages of flexible and convenient operation, slow and stable loading, and strong bearing capacity of the machine body.
