Load Frame, Motorised, 30 speeds, 50 KN (5,000 kgf)
Main features of the load frame is for Triaxial
and CBR Tests
The Load Frame consists of a cabinet which houses the gear system and motor
with sturdy angle iron frame. The loading is done through the bottom loading
platen, which is carried on a lead screw which advances upwards. The top
load bracket, which slides over two upright pillars, can be positioned at
any desired height and locked. It carries a hexagonal screw adapter for
standard proving rings. The loading part of the unit is detachable from the
main unit for ease of transport and to avoid damage to the tension rods.
Rates of strain: 30, between 6 mm / min and 0.00048 mm/min. By interchanging
the drive and driven gears, another set of 24 rates of strain can be
obtained. Operate on 230 V, 50 Hz, single phase, AC Supply.
Load Frame, Motorised, 12 speeds, 200 kN (20,000 kgf)
The Load Frame is extremely versatile and designed
to conduct triaxial shear test on soil and rock specimens. The instrument
consists of a cabinet, which houses the gear system and motor with sturdy
angle iron frame. The loading is done through the bottom loading platen,
which is carried on a lead screw, which advances upwards. The top load
bracket, which slides over two upright pillars, can be positioned at any
desired height and locked. It carries a hexagonal screw adaptor for standard
proving rings. The loading part of the unit is detachable from the main unit
for ease of transport and to avoid damage to the tension rods. Rates of
Strain: 12 (between 1.25 and 0.00032 mm/min) Suitable for operation on 230
V, 50 Hz, Single Phase, AC Supply.
Load Frame, Motorised, 12 speeds, 490 kN (50,000 kgf)
The Load Frame is designed for conducting triaxial
shear tests on rock specimens, but its use can be extended to any field
where there is a requirement of the rates of strain of this load frame to be
applied. This load frame gives a choice of twelve rates of strain from
0.000125mm/ min to of 5mm/min. Suitable for operation on 3 Phase, 415 V, AC
Supply. It consists of a cabinet housing the electric motor, reduction gear
and the turret gear box. Two pillars are fitted on the base over the
cabinet. The load is applied by advancement of a lead screw. A suitable
adapter is provided for fixing a 500 kN capacity proving ring which is
supplied at extra cost. This load frame has a platen of about 25 cm dia to
house the High Pressure Triaxial Cell.

- Proctor Penetrometer, Spring Type, 0-40 kg x 1
The instrument consists of a needle attached to a spring loaded
plunger, the stem of which is calibrated to read 0 to 40 kg division.
Long stem is graduated at every 12.5mm to read depth of penetration and
for use with needles of larger areas . The small penetration stem is
also graduation in 12.5mm division and is used with needles of smaller
areas. Needle points one each of 0.25, 0.5, 1.0, 1.5, 2.0, 3.5 and 6.0

- Proctor Penetrometer, Hydraulic Type, 0-40 kg x 2
This instruments is same as above but the penetration pressure on the
needle is conveyed through a hydraulic system Comprises hydraulic
proctor needle system complete with a pressure gauge fixed at easily
readable angle reading 0-70 kg x 2 kg. A set of needle points consisting
one each 0.25, 0.5, 1.0, 1.5, 2.0, 3.5 and 6.0 sq. cm. and a wooden
- Penetrometer, Proving Ring Type. (Vicksberg Penetrometer)
Simple and light instrument for measuring static penetration
resistance. The thrust force is provided directly by the operator who,
by pushing on the T handle, forces the cone into the soil.The
encountered resistance is measured on the fitted load ring. Testing is
only possible in soils with good consistency and for short depths.

Sample Riffle Divider
For the rapid collection of true representative
samples from aggregates, sand and fillers, sample divider is required.
Riffle Sample Divider consists of a metal box fitted with a series of chutes
of equal width, which discharge the material alternatively in opposite
directions into separate pans. The chutes of the riffle are steep enough to
allow rapid flow of the material.
