Flexure Strength


IS: 516, IS: 9399, BS: 1881, and ASTM C78
The Flexure Strength Testing Machines are designed to provide maximum rigidity throughout their working range. The downward movement of Hydraulic ram applies the load. The jack can be raised or lowered for testing different size beams. The load is indicated on a calibrated Bourdon tube type load gauge of range: 0-100KN X 0.5KN (0-10,000 kgf X 50 kgf). The load gauge is calibrated against NPL/NCCBM certified proving ring
Flexure Strength Testing Machine (concrete slabs)
IS:4969
This Flexural Strength Testing Machine is designed to suit the requirements to test precast Cement Concrete slabs for Canal Lining. The machine consists of a Bench Mounting type loading unit having a capacity of 25kN (2,500 kgf) with a self retracting type jack and a hand operated hydraulic pump. A 25 kN x 0.25 kN capacity pressure gauge, with maximum load indicating pointer, is attached to the pump. The machine has a set of platens, the top platen has a self aligning roller fixed at the centre and the lower one has two rollers of 25 mm dia, equally spaced at a distance of 15 cm. These rollers are hard chrome Plated to increase the abrasion resistance and hardness. Suitable for operation with 230 volts, 50 Hz, and single phase, AC Supply
Available Models are:
SCO-1054
Loading capacity 25 KN manually operated
SCO-1055
Loading capacity 100 KN manually operated
SCO-1056
Loading capacity 100 KN Motorised

Flow Test


IS1199, ASTM C124, AASHO T120, and T126:
The Flow Table is designed for determining the workability of Portland cement concrete. The Flow Table top is 76.2 cm dia, finely machined from a solid brass casting. The integral cast ribs are designed for support and strength. The stand is fabricated out of cast iron and is of sturdy construction. Holes for mounting of foundations are drilled in the base plate. The ground and hardened steel cam is designed to drop the table by 12.5 mm. The following model is offered

Hydraulic Jacks


SCO-1060
Hydraulic Jacks have multipurpose utility, i.e. application of loads while engaged in field investigation, determination of load carrying capacity of piles in the field, tensioning of wires in pre-cast structures, loading of members of any structure for deformation characteristics, etc. The jacks are supplied complete with manually operated pumping units fitted with Bourdon tube type pressure gauge and a steel-connecting pipe. All the jacks have a piston travel of 75 mm and jacks up to 500 KN capacity are provided with retraction springs. These are available in the following ranges
Note For all the above-mentioned jacks, the piston travel 150 mm, if specified can be made, at an extra cost. High Pressure Flexible Hose Pipe is required for connecting the pumping unit to the Hydraulic Jack. This is an essential extra to be ordered with any of the above jacks. The hose pipe is available in varied lengths as tabulated.
