Triaxial Load Frames

Triaxial Load Frames and components are ideal for unconsolidated-undrained triaxial soil testing in compliance with ASTM D2850. For testing consolidated-undrained, or consolidated-drained specimens under ASTM D4767, only the HM-397 model can be used. These versatile load frames can be used for different load tests in the lab; the table below provides a good reference tool.


Load Frame, 0.001—0.1in/min, 10,000lbf
Models: HM-396, HM-396F
Load Frame, 0.0001—0.3in/min, 10,000lbf
Models: HM-397, HM-397F
Load Frame, 0.00001—0.29999in/min, 20,000lbf
Models: HM-399, HM-399F
Load Frame, 0.02—2.0in/min, 10,000lbf
Models: HM-398, HM-398F

Load Frame Comparison Table

Click the Load Frame Comparison Table above to enlarge, print, or download. The table 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.
