Rock Testing Equipments

Our wide range of Brazilian test apparatus are used for indirect measurement of tensile strength of rocks. These meets the requirements of IS:10082-1982 for use with ‘NX’ size core samples. Further, our equipment comprises of the following:

• Loading frame with 100kN capacity, having a base and a cross head joined together with two solid pillars with nuts. At the top, the pillars have long threads for height adjustment and on the base, a 100kN hydraulic jack is centrally fixed between the pillars. This jack has an integral pumping unit and oil reservoir.
• A 100kn capacity pressure gauge is fixed to the jack for indicating the load on the specimen and also an operating handle is provided with the jack.
• Brazilian Attachment for ‘NX’ core size specimen with thickness half the diameter with two loading jaws. The lower jaw has two guide pins fixed with it and the upper jaw has two guide holes for the guide rods to hold the two jaws aligned. Further, the upper jaw has a spherical seating on the upper side to seat a ball for self-alignment and supplied complete with the steel ball.

We offer rock bolt pull out test, which are made as per the B.I.S. 11309, ASTM D4435, ISRM standards. These are used to measure the working and ultimate capacities of rock bolt anchors.

Further, our products comprises of a central hole jack, hand pump with load gauge, directional control valve and only for central hole jacks above the capacity of 500kN, flexible pipes, truss high tensile test rod with coupling.

Moreover, the load cell can be used for the measuring of pull out load and arrangement is provided for fixing dial gauge for estimating deflection against the load. In addition to this, we provide different size of adopters with the high tensile test rod.
