Core Cutting Machine Rock Drill.

The objective of the test method is to measure the working and ultimate capacities of rock bolt anchors. The system comprises of a central hole jack,hand pump with a load gauge, directional control value (only for central hole jacks above the capacity of 500 kn), flexible hose pipe 5 mts, truss high tensile bolts with coupling. In general the pull out force is indicated on the load gauge, however a load cell with digital indicator can be used to measure the pull out load. Arrangement is provided for fixing the dial gauge for estimating deflection against the load. 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.
