In KRRASS’s words
“KRRASS torsion-bar press brakes use a thick, full-length mechanical connecting bar to synchronize the left and right hydraulic cylinders.”
“E21 Simple control for X-axis back gauge, ram stroke, and multi-step bending jobs. E310P 4-axis CNC for X/Y/R/C and servo backgauge control. Auto-calculates bend depth from angle, material, thickness, and tooling. E315PS Practical control for torsion-bar press brakes and everyday bending jobs. ESA S829 Touchscreen ESA-S829 control for 2-axis NC press brakes. Pairs with ESA servo motor and precision backgauge setup.”

Where these figures come from
Read from the specification table on KRRASS’s product page at krrass.com (row “125T/4000”) on 27 October 2026. Values are copied cell by cell and never estimated; force given in kN is divided by 10 for tonnes, and a working-speed range is shown by its upper value.
