Single sample Soil direct shear test machine

Single sample Soil direct shear test machine 

Application: 

The test covers the determination of consolidated drained shear strength of a soil or sand material in direct shear. The Automatic Direct / Residual Shear Test Machine is supplied complete with load hanger, carriage assembly and an integral 9:1, 10:1 and 11:1 lever loading device. The apparatus is also motorized and floor mounted. The beam loading device, which is used to strengthen the vertical load on the shear box assembly, can hold up to 50 kg of weight. The total load on the specimen can reach up to 5 kN.

The machine is compatible with a range of square and 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.

Our direct shear test apparatus is a motorized dead weight testing machine designed for direct and residual shear testing on undisturbed and remolded soil specimens. The machine uses a 10:1 beam loading device to control confining pressures, a load cell with readout measures shear pressure and a displacement transducer to measure shear and vertical displacement.
