Gilson’s multi-purpose Load Frames are versatile and used for a wide range of laboratory soil tests such as Unconfined Compressive Strength, California Bearing Ratio (CBR), Limerock Bearing Ratio, Soil Cement, Flexible Wall Permeability and Triaxial testing when fitted with required component sets. The MS-86 Marshall Stability frame has a fixed strain rate for testing hot mix asphalt, while the adjustable strain rate of the MS-398 and HM-398 models provides flexibility for both soil and hot mix asphalt testing. The table below indicates the typical testing applications for which each model is designed.

The load frames in this series are designed to work with a variety of digital and analog sets and other ancillary products, ensuring each testing lab can create a test system that meets specific needs. A simple change of components easily adapts the unit for different testing application or data acquisition requirements.
Models have a force 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 1/8, 1/4 or 3/4hp DC motors and controllers regulate strain rates to ±1% of set point. Sturdy, 14-gauge powder-coated steel enclosures have adjusting nuts on the 1.25in (32mm) coarse-threaded rods to quickly adjust the horizontal cross-head height.
