Stand-Alone, Four-Point Bending Beam, Small, 4-Point Machine, 110/220V 50/60Hz

The Stand Alone Four Point Bending Beam Machine uses advanced servo pneumatic technology and a high-speed digital data acquisition and control system together with user-friendly software. During testing both graphical and tabular data are displayed on screen and test data is stored to disc in Microsoft® Excel® compatible format. The clamps are at 118.5mm (4.67 inch) centers (the distance between the outer clamps is 335.6mm (14 inches) according to AASHTO specifications but the height and width of the beam can be varied).

Features:

• Frequency range 0.1 to 30Hz¹
• Low cost pneumatic stand alone four point bending machine
• Low-friction actuator and high performance ceramic spool servo-valve
• On-specimen measurement system removes errors due to frame flexure
• Designed for AASHTO beam sizes
• Sinusoidal controlled strain or controlled stress fatigue test modes
• Constant torque motorized specimen clamping to eliminate errors due to localized beam indentation
