ROCK SHEAR BOX APPARATUS - DIGITAL
The equipment is used for Direct Shear Laboratory Test of Rock Samples. The test measures peak & residual Direct Shear Strength as a function of stress normal to the sheared plane. The equipment can be used for testing Core, Lump specimens.
- The machine is ideal for the testing onsite and in laboratory.
- Equipped with 4" touch screen controller
- Load and displacement will be displayed on the single screen
- The touch screen comes with 48 hours of battery back up to test the samples on site
- Simple plug and play instruments
The apparatus consists of a shear box designed to accept samples not larger than 115×125 mm, or alternatively cores up to 102 mm dia. The shear box consists of two halves, the upper being connected to two rams for reversible shearing action and the lower connected to a ram for normal load application. The loads are recorded by by pressure transducers. The normal loading system is complete with an adjustable low friction pressure maintainer to absorb volume changes of the specimen during the shearing action and to ensure a constant vertical stress. Supplied complete with 2 Nos. Mould former, a 6 channle data logger (2 for load and 3 for displacement measurement) Battery operated (48 hours continuous running) suitable to use on the field
