Tensile Machine

Steels used in construction are integral part in building structure other than concrete. Unit Test series of PC controlled fully automatic tensile testing machines provide reliable tensile test of common steel used in construction such as steel bar, pc strand & others. Its rugged high stiffness frame is made using extremely solid steel which is virtually indestructible or unbendable, thus provides very consistent test results over many years of usage. Silent operation & low temperature makes it suitable to be placed even indoor with office environment with extremely minimal disruption.

Upon sample failure, the pressure will be hold automatically to allow removal of broken samples at ease. Movement of jaws by hydraulic system from main pump, to ensure proper grip during test. Precise test speed control by servo feedback control unit with high precision & energy efficient long lasting DC motor.

The frame is designed to carry out tensile test using wedge grips placed in hydraulic or manual clamping heads, due to international standards by using accessories devices. The hydraulic servo controlled unit regulates the load rate by computer. As per international safety standards required, an emergency device is built in to stop the machine in any moment. A control pedal situated on frame governs the movement of the top tensile head for an easier positioning of the specimens according to its length. The machine supplied complete with loading frame, control console, PC with software, extensometer, set of wedge grips and printer.
