INTRODUCTION
The versatile HM-397B Load Frame can be utilized for multiple soil
tests. Individual component sets can be fitted to the load frame to
perform California Bearing Ratio (CBR), Unconfined Compressive
Strength, Soil Cement, and Triaxial tests.
This 10,000lbf (44.5kN) capacity frame has a strain rate of
0.00001—0.29999in/min (0.000254—7.62mm/min) controlled
to +/- 1% of set point. Front panel controls allow the operator
to adjust the direction and speed of the platen. The strain rate
is set using the thumbwheel selector. Sliding the cross-arm up
or down the coarse-threaded 1.25in (32mm) diameter rods and
tightening the nuts makes adjustment for the wide variety of
testing components quick and easy.
