Direct Shear Appratus
Digital Direct / Residual / Shear Apparatus
ASTM D3080; BS 1377:7; AASHTO T236, CENISO/
TS 17892-10
The test covers the determination of consolidated drained shear
strength of a soil material in direct shear. This Automatic
Direct / Residual Shear Test Machine is motorized and
floor mounted. Supplied with carriage assembly load hanger
and integral 9:1, 10:1 and 11:1 lever loading device as
standard. The beam loading device which is used to amplify
the vertical load on the shear box assembly can receive up to
50 kg of weight. The total load on the specimen can reach up
to 5 kN (5000 N).
The machine accepts 60 mm square, 100 mm square, 60 mm dia. round, 100 mm dia. round and 2.5 inc. dia. round shear box assemblies. All shear box assemblies are designed to contain water that surrounds the specimen. The Assemblies consist of a shear box with a rigid wall square or round hole complete with a vertical loading pad grooved back face, a grooved retaining plate, 2 pcs. porous plates, 2 pcs. plane grids and 2 pcs. perforated grids.
The shear machine is driven by high resolution servomotor and gear box assembly. Speed range is fully stepless variable over the range 0.00001 to 9.99999 mm/min for both direction( forward and reverse). After test the reverse speed is 10 mm/min.). 5 kN load cell is used for load measurement. 10 x 0.001 mm and 25 x 0.001 mm sensitivity linear potentiometric transducers are used for vertical and horizontal displacement measurements respectively. Displacement limits are controlled by limit switch.

Direct Shear (Motorised Twelve Speed)
IS 2720 (PART XIII)
The apparatus comprises of the following.
Loading Unit:
Supplied with load yoke with direct and lever system for applying load. Normal stress capacity 8 kg/sq. cm. Load is applied either directly or through a counter balanced detachable lever. Provision is made for the load to be applied either through a steel ball recessed in the loading pad or direct through a boss on the pre calibrated loading yoke. The loading unit is provided with V strips and roller strips for frictionless movement of shear box housing.
Comprising direct shear box in two halves for a square specimen size 60 x 60 x 25mm one pair of plain gripper plates, One pair of perforated gripper plates, one pair of porous stones, one top of loading pad.
Shear Box Housing:
Accommodates the direct shear box assembly. Complete with two ball roller strips. Specimen cutter: for cutting 60 x 60 x 25 mm. Specimen form larger samples. Set of weights to give a normal stress of 3kg/sa.cm.
