Direct Shear Test Apparatus
Product Code : EL-STLE-10372
Quick Answer: The Direct Shear Test Apparatus is an electrically operated soil-testing instrument used to determine the shear strength of soil specimens by the direct shear method. It tests square specimens measuring 60 x 60 x 25mm inside a shear box housing, applying normal stress up to 8 kg/sq. cm through a load yoke and driving the shear box at 12 selectable rates of strain from 0.0002 to 1.25 mm/min. The unit runs on a 230 Volts Single Phase A.C. supply and is supplied with a compression proving ring, consolidation and strain dial gauges, and a set of calibrated weights for applying normal stress.
The apparatus comprises of the following:
Loading Unit: The apparatus is supplied with a load yoke featuring a direct and lever system for applying load, with a normal stress capacity of 8 kg/sq. cm. Load can be applied either directly or through a counter balanced detachable lever, with provision for the load to be applied 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.
Shear Box Assembly: 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 and is 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/sq.cm.
Through larger as following :

Complete set as above but without proving ring.
Net weight: 140 kg.
Essential Accessories:
High sensitivity compression proving ring, capacity 200kg.
One consolidation dial gauge 0.01mm x 25mm and one strain dial gauge 0.01mm x 25mm
Optional Extras:
Additional set of weights to give a normal stress of 5 kg/cm2.
Soil sampler for 60mm x 60mm specimen and test forms pad of 50.
Spares:
Porous stone for 60mm x 60mm size sample available in pairs.
The unit is electrically operated and provides 12 selectable rates of strain: 1.25, 0.625, 0.25, 0.125, 0.05, 0.025, 0.01, 0.005, 0.002, 0.001, 0.004 and 0.0002 mm/min, and operates on a 230 Volts Single Phase A.C. supply.
