Model 2001-D, 2001-DF Direct Shear Machine

INTRODUCTION

The Karol Warner model 2001-D Direct Shear Machine
is a tabletop unit that provides direct or direct/residual
shear values for evaluating the strength and stability of
soils. This device utilizes a pneumatic loading piston
for applying the vertical load to the sample. A calibra-
tion chart is included for setting the high load or the low
load via the Fairchild Regulator while a built-in digital
readout displays the vertical load in psi.
This Direct Shear Unit has a strain rate of 0.0001 – 0.3
in/min (0.0025 – 7.62 mm/min) with a maximum shear
displacement of 0.8in (20.3mm) and the travel speed
is set with the thumbwheels on the left side of the unit.
The residual shear force is determined by a load cell
and while real time load settings and peak load are dis-
played on the digital readout. Consolidation and shear
displacement are measured with Displacement trans-
ducers and displayed on a digital readout.
