Description
Liya Test Fully automatic Direc Shear device is an advanced system specifically designed to perform consolidation, direct and residual shear stages in a fully automated way. The system is based on an electroservo motor system which along with a high-performance regulator guarantees an automatic application of a vertical load up to 10 kN, thus offering the unique possibility to reduce to the absolute minimum any form of manual intervention (no need of dead weights or level arms).
The test measures the consolidated drained shear strength of a soil material in direct shear. Automatic Direct Shear Test Machine is motorized with servo motor and measuring sensors are electronically connected to a digital readout unit to get accurate readings. Supplied with carriage assembly load hanger and integral 9:1, 10:1 and 11:1 lever loading device as standard. The loading arm 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.
The shear machine is driven by high resolution servomotor and gear box assembly. Speed range is fully steeples variable over the range 0.001 to 9.9999 mm/min. 5 kN load cell is used for load measurement. 10 x 0.002 mm and 25 x 0.01 mm sensitivity displacement sensors are used for vertical
and horizontal displacement measurements respectively.
Displacement limits are controlled by limit switch.
The machine shear box tests on 60 mm and 100 mm square, Ø 60 mm round, Ø 100 mm round and Ø 2,5” round samples. All Shear box assemblies can contain water that surrounds the specimen. The Assemblies consist of a shear box with a rigid wall square, complete with a Vertical Loading Pad grooved back face, a Grooved Retaining Plate, 2 pieces Porous Plates, 2 pieces Plane Grids and 2 pieces Perforated Grids.
Direct Shear Test Machine Supplied with Slotted Weight Set.
Shear Box Assembly, Specimen cutter and Extrusion Dolly should be ordered separately depending on the sample size.
