Gilson Load Frames are manufactured in cooperation with Karol-Warner and models listed here are ideal for laboratory California Bearing Ratio (CBR) Testing when outfitted with suitable components. A quick change of components easily converts Load Frames for use with other soil testing applications, such as Unconfined Compressive Strength or Triaxial loading. The chart below indicates their individual capabilities and capacities.
The Gilson Manual CBR Load Frame is designed with separate hand-operated cranks for loading, and doesn’t require an additional component set.
View or download the Load Frame Comparison Chart which indicates force capacity and strain rate for common geotechnical testing applications.
Models have a capacity of 10,000 or 20,000lbf (44.5 and 89kN) with 11.9x37.3in (302x947mm) WxH frame openings. Platen diameter is 8in (203mm). Units run on 3/4hp DC motors and controllers regulate strain rates to ±1% of set point. Sturdy, 14-gauge painted steel enclosures have adjusting nuts on the 1.25in (32mm) coarse-threaded rods to quickly adjust the horizontal cross-head height.
