便携式点荷载仪

The point load test is a simple portable device used to determine the strength index of rock samples(index test) and unconfined compressive strength. This test can be performed quickly and easily on rock specimens without special handling either in the laboratory or in-situ.

Germany wille The portable point load tester provide an index for the strength classifi cation of hard rocks and allows a quick and non-expensive on-site evaluation of stone strength of hard rocks.

A sample of rock is mounted between two pointed platens and pressure is applied until failure of the sample occurs. The peak-applied load is recorded and used to calculate the point load index.


Type of tests : Diametral Test, Axial test, Prismatic test, and Test on an irregular sample(Block Lump Test)
