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 Load Frame model can be used. These versatile load frames can be used for different load tests in the lab; the chart 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

Sieve Shaker Comparison Chart

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.
