Digital Point-Load Test Apparatus

Digital Point-Load Test Apparatus – ELE International

The ELE Digital Point-Load Test Apparatus is a versatile and accurate device for determining the strength classification of rock specimens. Designed originally at Imperial College London, the apparatus is used for rapid, non-destructive strength testing of rock cores and irregular rock fragments. Featuring a two-column frame and a hand-operated hydraulic jack, this point-load tester allows loads up to 55 kN and accommodates samples up to 101.6 mm in diameter. It meets the ASTM D5731 standard and provides direct digital readout of applied load, simplifying the determination of the point-load strength index.

Key Features of Digital Point Load Test Apparatus

• Digital Load Display: Provides accurate real-time pressure readings for enhanced precision.

• High Capacity: Capable of applying loads up to 55 kN for a wide range of rock types.

• Large Sample Compatibility: Handles specimens up to 101.6 mm in diameter.

• Robust Construction: Two-column frame with fixed crosshead ensures stability during testing.

• Integrated Scale: Built-in scale helps determine specimen diameter for calculating point-load strength.

• Manual Hydraulic Operation: Hand-operated jack gives user control during load application.

• Supplied With Safety Gear: Includes a heavy-duty face mask for operator protection.

Applications

• Rock Strength Classification: Ideal for preliminary classification of rock strength in the field or laboratory.

• Core and Fragment Testing: Suitable for both core samples and irregular rock fragments.

• Geotechnical and Mining Surveys: Commonly used in site investigations for slope stability and excavation assessments.

• Teaching and Research: Perfect for educational institutions conducting rock mechanics instruction.
