ROCK POINT LOAD TEST APPARATUS

STANDARD: ASTM D-5731

This apparatus comprises a two-column fi xed 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 fi xed to the crosshead with a scale mounted on the frame to provide specimen diameter information for use in point load strength index calculations.

For model PL-01, its pressure is indicated on the pressure gauge, model PL-02 is indicated directly on the digital readout unit. Loads up to 50 k N can be applied to specimens as large as 101.6 mm in diameter.
