Compression Testing Machine for Rock Cores 2000 kN

Servo-controlled hydraulic compression machine with spherical seat for determining the uniaxial compressive strength of rock cores. Used in mining, tunnelling, dam foundation and rock mechanics investigations.

Specification

The frame applies steady axial load to prepared rock core cylinders and records peak load for uniaxial compressive strength. A stiff four-column frame and spherical seating allow accurate failure measurement of hard rock. Load rate control keeps results consistent with standard stress rates.

Features

• Four-column rigid frame with safety shield
• Pacing indicator for constant stress rate
• Peak hold digital load display
• Spherical seat top platen with hardened plates
• Suitable for NX, BX and HX core sizes
