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
