MANUAL ROCK SHEAR BOX APPARATUS (K222)

Product Code: K222

Category: ROCK MECHANICS

Sub-Category: SHEAR STRENGTH

• The Manual Rock Shear Box Apparatus is designed for determining the shear strength and stability characteristics of rock specimens under controlled normal and shear loads. It provides essential parameters such as cohesion, friction angle, and residual shear strength for rock slope stability analysis and foundation design.
• The system accommodates both irregular rock fragments and cylindrical core specimens, enabling versatile testing for geotechnical, mining, and civil engineering investigations.
• The test applies a normal load perpendicular to the failure plane, while shear load is applied horizontally through twin hydraulic rams to mobilize shear resistance along the defined shear plane.
• Manual control of normal and shear pressures allows precise simulation of in-situ stress conditions, making the apparatus suitable for laboratory and on-site evaluations.
• The apparatus ensures accurate displacement and load measurement through dial gauges or optional electronic transducers, allowing reliable data acquisition and repeatability.
• Constructed with a rigid steel frame and corrosion-resistant components, it ensures stable operation and long service life even under demanding testing conditions.
