Brazilian
Test Apparatus
Our wide range of Brazilian test apparatus
are used for indirect measurement of tensile
strength of rocks. These meets the requirements
of IS:10082-1982 for use with ‘NX’
size core samples. Further, our equipment
comprises of the following:
• Loading frame with 100kN capacity,
having a base and a cross head joined together
with two solid pillars with nuts. At the top,
the pillars have long threads for height adjustment
and on the base, a 100kN hydraulic jack is
centrally fixed between the pillars. This
jack has an integral pumping unit and oil
reservoir.
• A 100kn capacity pressure gauge is
fixed to the jack for indicating the load
on the specimen and also an operating handle
is provided with the jack.
• Brazilian Attachment for ‘NX’
core size specimen with thickness half the
diameter with two loading jaws. The lower
jaw has two guide pins fixed with it and the
upper jaw has two guide holes for the guide
rods to hold the two jaws aligned. Further,
the upper jaw has a spherical seating on the
upper side to seat a ball for self-alignment
and supplied complete with the steel ball. |

Digital
Rock Shear
We offer digital rock shear, which comprises
of two controllers, hydraulic power
pack with tandem pump to feed two actuators.
These are available in the sizes of 300 mm
x 300 mm x 450 mm, which can contain maximum
rock specimens of 300 x 300 x 150 mm that
are naturally or artificially jointed in any
shape and form.
Further,
the parameters like normal load and shearing
load on strain basis or stress basis are controlled
through the computer. In addition, on line
graphical presentation is shown on the monitor.
Moreover, after completion of the tests.
our range helps to plot the following graphs
on the window operated software.
• Shear force Vs horizontal displacement.
• Horizontal displacement Vs vertical
displacement.
• Shear stress Vs normal stress.

Rock Bolt
Pull Out Test
We offer rock bolt pull out test, which are
made as per the B.I.S. 11309, ASTM D4435,
ISRM standards. These are used to measure
the working and ultimate capacities of rock
bolt anchors.
Further,
our products comprises of a central hole
jack, hand pump with load gauge, directional
control valve and only for central hole
jacks above the capacity of 500kN, flexible
pipes, truss high tensile test rod with
coupling.
Moreover,
the load cell can be used for the measuring
of pull out load and arrangement is provided
for fixing dial gauge for estimating deflection
against the load. In addition to this, we
provide different size of adopters with
the high tensile test rod.

Core Drilling
Machine
Our range of core drilling machines are of
light weight, versatile and easy to operate.
These are designed with a tubular frame mounted
on two pneumatic tyres. In addition to this,
we also provide a hook in the front side of
the frame to be towed behind a jeep and the
tyres have been so placed that the total machine
is balanced.
Further, the main gear box gives a manual
feed of 600 mm can be rotated in any direction
that is 0-360o for a convenient angle of drilling.
It is powered by 4.8 H.P. diesel engine and
suitable for taking cores up to the diameter
of 150 mm and depth more than 4-5 meters with
help of extension rods and bits. |
