Gilson HM-397 Operating Manual

0.0001—0.3in/min, 10,000lbf (44.5kN)
INTRODUCTION
The versatile HM-397 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
0.0001—0.3in/min (0.00254—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.
