The 7731 Karol-Warner Load Frame is an economical Load Frame that can perform a variety of soil tests. Its 20,000lbf (89kN) capacity and wide strain rate of 0.00001 – 0.29999in/min (0.000254 – 7.619mm/min) cover California Bearing Ratio (CBR), Unconfined Compressive Strength (UC), Triaxial and Soil Cement Testing when equipped with proper load and displacement components. The reliable DC stepper motor regulates speed to within ±1% and is matched to the unique speed and torque requirements of the Load Frame.
With its sturdy powder-coated steel cabinet and precision loading screw with a protective boot, the Load Frame can handle even the most severe lab environments. Front panel controls allow the operator to adjust the direction and speed of the 8in (203mm) diameter platen, as well as select the strain rate. The vertical 1.25in (32mm) diameter rods allow for a quick change of crossarm height.
