Portable Point Load Test Apparatus
The portable point load tester provides an index for the strength classification of hard rocks and allows for a quick, non-expensive on-site evaluation of hard rock strength.
A sample of rock is mounted between two pointed platens. Pressure is then applied until failure (breakage) of the sample occurs. The peak-applied load is recorded and used to calculate the point load index.
The standard test-set is consisting of:
- Hydraulic cylinder with conical pistons
- Hydraulic pump
- Digital-manometer with pressure and load display
- Base plate
- Operator protection set
- Operating manual
- Easy to handle, functional design
- High-level stiffness and light-weight frame with special, hardened conical pistons
- Suitable for testing samples up to 120 mm in diameter
- Hand-operated hydraulic pump, pressure cylinder, aluminum base plate
- High quality hydraulic components with fine adjustable two stage hydraulic pump
- Height adjustable, stiff crosshead for different sample heights
- Version with digital precision pressure gauge Cl. 0.1% with maximum memory, IP 65, resolution 0.01 kN
- Version with analogue pressure gauge, pressure range: 0 - 100 kN and 0 - 25 kN, accuracy: 1.0 kN resp. 0.5 kN
- Digital measuring device for axial strain
- Splinter protection
