Digital Point Load Tester

The strength of rock can be quickly determined in the field on core or irregular lump samples by using the Digital Point Load Tester. The frame, loading jack and digital readout are supplied as an integral unit mounted on the base of the carrying case. Loading pressures up to 13,000 lbf. (55 kN) can be applied to specimens as large as 4” (101.6 mm) in diameter. A scale mounted on the frame provides specimen diameter information for use in point load index calculations.

Digital Point-Load Test Apparatus

Originally developed at Imperial College, London, the 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. Pressure is indicated directly on the digital readout unit. Loads up to 55 kN can be applied to specimens as large as 101.6 mm in diameter.

The apparatus is supplied complete with heavy-duty face mask.

Standard: ASTM D5731
