Direct Shear Apparatus

Product Details:

The test covers the determination of consolidated drained shear strength of a soil material in direct shear. This Direct 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.

SPECIFICATIONS

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 gearbox assembly. Speed range is a fully step-less variable over the range 0.00001 to 9.99999 mm/min for both directions ( forward and reverse). After the 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 a limit switch. Shear Box Assembly, Slotted Weight Set, and other optional accessories including specimen cutter and extrusion dolly should be ordered separately.
