Multitech Scientific Instruments - Tensile Testing Machine

Standard Used : 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. 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

Available from 3 ton to 50 ton

Standard Used : IS 10082-1982

Specification: The instrument is useful for testing specimen from 50mm dia to 100mm and of thickness of half the diameter. This is to test for indirect measurement of tensile strength of rocks. The specimen is held in circular jaws, this is primarily similar to a compression machine and consists of a small load frame having sturdy base with two vertical threaded rods and an adjustable cross head. The hydraulic jack is fitted at the centre of the base of the load frame. The jack of the load frame is self retracting and two plain platens are supplied. A pressure gauge capacity 0-100 kn x 1 kn is fixed at the base of jack. A maximum pointers is also provided on the gauge, a pair of semi circular platens for 50mm dia samples also provided. The instrument can be used in field also.

Optional Extras: Pair of jaws for samples dia (a) 60mm (b) 70mm (c) 80mm (d) 90mm (e) 100mm.
