Load Frames

Gilson Load Frames by Karol-Warner are adaptable for a wide range of laboratory soil tests such as Unconfined Compressive Strength, California Bearing Ratio (CBR), Limerock Bearing Ratio, Soil Cement, Flex-Wall Permeability and Triaxial testing when fitted with required Component Sets. The Marshall Stability Load Frame and Pro-Loader II Load Frame for Hot Mix Asphalt are used in asphalt testing.

This series of load frames is designed to work with a variety of digital and analog sets and other ancillary products, ensuring each user can create a test system that meets specific testing needs. A simple change of components easily adapts the unit for different soil 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.
  • Load Frame, 0.001—0.1in/min, 10,000lbf a high-speed platen advance rapidly positions the platen for faster set-up.
  • Load Frame, 0.0001—0.3in/min, 10,000lbf  the micro-stepping drive controller allows more precise control of loading rates.
  • Load Frame, 0.00001—0.29999in/min, 10,000lbf features a precision strain rate allowing for testing of sensitive soils. The micro-stepping motor and drive controller precisely control load rates.
  • Load Frame, 0.00001—0.29999in/min, 20,000lbf features an enhanced strain rate for sensitivity. The best choice when testing ASTM D4767 consolidatied/undrained triaxial tests.
  • Load Frame, 0.02-2.0in/min, 10,000lbf allows use for a wider range of test methods. Digital and analog components and sets that attach to the Load Frame are available for Unconfined Compression, CBR, Soil Cement and Triaxial testing.
  • Marshall Stability Load Frame with 10,000lbf (44.5kN) capacity has a fixed loading rate of 2in (50.8mm) per minute as indicated for Marshall Testing of asphalt specimens.
  • Load Frame, 0.02-2.0in/min, 10,000lbf for Hot-Mix Asphalt offer versatility and solid performance with hot-mix asphalt specimens in Marshall and Lottman Testing, as well as with laboratory soil testing such as CBR, unconfined compression, soil-cement, and basic triaxial tests.
