Rock Bolt Pull Out Test Apparatus
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.
Load Frame For Universal Compression Test Of Rocks 12 Speed 200 Kn
Specification:
This equipment is used for determining unconfined compressive strength of intact rock core
specimens. The rock sample is cut to length and the ends are machined flat. The specimen is
placed in a loading frame and if required heated to the desired test temperature. Axial load
is continuously increased on the specimen until peak load and failure are obtained.
The equipment consist of the following replaceable parts :
Load frame, 200 kn capacity 12 speed from 0.0064 to 1.25 mm/min
Proving ring, 200 kn with calibration certificate
Dial gauge 25mm travel, 0.01mm least count.
Platen set as per ASTM 2938 requirements
Platen set as per ASTM 2938 requirements
Horizontal clearance 300 mm
Vertical clearance 750 mm
Maximum platen diameter 198 mm
Maximum platen travel 100 mm
Specimen diameter 38 mm to 100 mm
Can test AX, BX, NX rock specimen upto 100 mm
Hoek Triaxial
Specification:
Hoek Cells have been designed to be used for triaxial testing of rock specimens.
Hoek Cells comprise a steel body complete with two quick release self-sealing
couplings, two steel end caps which are screwed to the cell body, 2 pieces of
upper and 2 pieces of lower loading caps with spherical coupling and a rubber
sealing sleeve to separate the specimen from the cell fluid.
