Rock point load test apparatus
Rock point load test apparatus

PL-02

This apparatus comprises a two-column fixed crosshead frame and a hand operated hydraulic jack. Pressure applied by the jack extends the piston carrying the lower conical point. The upper point is fixed to the crosshead with a scale mounted on the frame to provide specimen diameter information for use in point load strength index calculations.

The upper point is fixed to the crosshead with a scale mounted on the frame to provide specimen diameter information for use in point load strength index calculations.

Its pressure is indicated on the pressure gauge, model PL-02 is indicated directly on the digital readout unit.Loads up to 100 kN can be applied to specimens as large as 90 mm in diameter.
