LOAD FRAME FOR UNIVERSAL COMPRESSION TEST OF ROCKS12 SPEED 200 KN AZA1007
The AZA1007 Universal Compression Test Load Frame is a heavy-duty mechanical and hydraulic testing system specially designed for determining the uniaxial compressive strength (UCS) and deformation behavior of rock core specimens. Engineered for precision and durability, this equipment is widely used in geotechnical laboratories, civil engineering institutes, mining operations, tunneling projects, and research organizations.
Built with a 200 kN high-capacity loading system and a 12-speed gear control mechanism, AZA1007 allows highly controlled and uniform load application, ensuring repeatable and accurate test results. Its rigid steel construction minimizes frame deformation during testing, offering maximum stability and long service life even under heavy laboratory workloads.
This load frame is manufactured to comply with ISRM Suggested Methods and ASTM D7012 requirements, making it a reliable solution for internationally accepted rock strength testing.
Description
Why Rock Compression Testing is Important
Rock compression testing determines the maximum axial stress that a rock sample can withstand before failure. This data is essential for:
-
Foundation and footing design
-
Tunnel and underground support planning
-
Slope stability and landslide assessment
-
Dam and hydropower project safety analysis
-
Seismic and rock fracture behavior studies
AZA1007 enables engineers to obtain these critical parameters with high accuracy.
Working Principle
The machine operates using a vertical compression system where cylindrical rock core specimens (typically Ø50–100 mm) are placed between hardened steel platens. A hydraulic or mechanically driven system applies a steadily increasing compressive load.
The 12-speed gearbox allows operators to adjust loading rates based on rock type and testing standards. A calibrated load indicator displays force in real time, while optional digital systems can record stress–strain curves for advanced analysis.
