HBT-A Series (500kN-3000kN)
The bending testing machine adopts a robust three-cylinder loading structure, enabling rapid and flexible adjustment of test span and supporting full 180° bending of metallic plates and welded components. Designed for high-capacity flexural evaluation, the tester is capable of both constant loading-rate control and constant displacement-rate control, with seamless switching between the two modes.
