20,000lbf (89kN), 0.00001—0.29999in/min
INTRODUCTION
The versatile HM-399 Pro-Loader 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 20,000lbf (89kN) 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 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.
