Description:

Rock point load test apparatus

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 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.

Specifiction

model PL-02 is indicated directly on the digital readout unit.

Loads up to 50 kN can be applied to specimens as large as 101.6 mm in diameter.

Max work pressure: 60Mpa

Piston diameter: dia.35mm

Pistion stroke 160mm

Piston area: 9.62cm2
