CBR Load Frames

Gilson CBR (California Bearing Ratio) Load Frames are manufactured in cooperation with Karol-Warner and are ideal for CBR Testing in the laboratory. A quick change out of available test components converts Load Frames for use with other soil testing applications such as Unconfined Compressive Strength or Triaxial loading. Gilson offers a unique variety of Load Frames suited to your application.
  • Pro-Loader Load Frames have a 10,000lbf (44.5kN) capacity, 3/4hp DC motors and controllers to precisely regulate the variable strain rates to ±1% of set point. Models are available with maximum strain rates of 0.1in (2.54mm) or 0.3in (7.62mm) per minute.
  • Pro-Loader II Load Frames features similar construction with a higher overall strain rate and do not use a high-speed platen advance. Strain rate is from 0.02 to 2.0in (0.508 to 50.8mm) per minute.
  • Manual CBR Load Frames have separate hand-operated cranks for platen positioning and testing operations. The press meets specifications when cranked at the required speed.
  • CBR Stress/Strain Kits & Component Sets quickly install onto Load Frames and feature high-quality analog or digital instrumentation required to perform laboratory CBR Tests.
