Description

IS 11309, ASTM D 4435
Specification:
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
