Automatic Direct Shear Test Machine

STANDARDS : ASTM D3080; BS 1377:7; AASHTO T236, TS 1900-2, CEN-ISO-TS 17892-10

The test measures the consolidated drained shear strength of a soil material in direct shear.

Automatic Direct – Residual Shear Test Machine is motorized and floor mounted.

Normal stress is applied to the specimen by utilizing a weight hanger, a lever arm(amplification ratios of 9:1, 10:1 and 11:1), and a vertical loading yoke.

Hanger can receive up to 50 kg of weight which is amplified by the lever arm and transferred to the specimen by the vertical loading yoke as a normal force

up to 5 kN (5000 N).

The machine is supplied with a shearbox bowl that accepts 60 mm square, 100 mm square, 60 mm dia. round, 100 mm dia. round and 2.5 inc. dia. round shearboxes.

Shearbox bowl is designed to contain water to inundate the specimen during the test.

The shearbox assemblies consist of rigid upper and lower shearbox frames with lifting and locking screws, a grooved loading pad, a grooved base plate, porous

plates (2 pcs.), and perforated plates (2 pcs.).

Drive unit utilizes a high resolution servomotor and a gear box assembly to ensure continuously variable transmission of speed in a range from 0.00001 mm-min. to

15 mm-min for both forward and reverse directions.

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

displacementmeasurements respectively.

Displacement limits are controlled by limit switch.

*** Shearbox Assemblies, Slotted Weight Sets or Individual Weights and other optional accessories including cutting ring and extrusion dolly should be

ordered separately.
