Integral Proving Rings

Integral Proving Rings
Integral Proving Rings
Item code: ESTE-83

The Proving rings are made of special steel carefully forged to give maximum strength and machined to give high sensitivity commensurate with stability ensuring long life and accuracy. All proving rings are integral type viz, the loading (outside) bosses are forged integral with the ring body. This ensures that there is no possibility of abutment shift and consequent loss of accuracy in reading that always exists with bolted abutments. The dial gauge and anvil are mounted on U-brackets clamped to the ring body by set screw. The dial gauge is fitted with a special back cover and threaded bush. Which does not permit any shift from the original dial alignment, coaxial with the loading boss centres, that is set at the factory before calibration. For all compression proving rings and tension compression proving rings up to and including 5 KN capacity the loading bosses have female threading ½” BSP (16 TPI) The boss faces are ground and polished and are plane parallel to within 0.2mm total DTI run out.

Tension compression rings have their integral loading bosses male threaded, 1.25” dia, 8 tpi square thread, 1.25” long. Caps are provided for use when loading in compression Repeatability is as stipulated in IS 4169 The rings are supplied complete with dial gauge and Works calibration Chart. Individuallypacked in polished wooden. Boxes. NCCBM Calibration can also be arranged for any proving ring at an additional cost. Proving rings to meet special requirements are also available on request. Separate polished and ground pair of Loading Pads FOR Compression Proving Rings and Pair of Shackles for Tension Proving Rings are provided to suit each proving ring, at extra cost.

Direct Shear Test Apparatus

Direct Shear Test Apparatus
Direct Shear Test Apparatus
Item code: ESTE-93

The Direct Shear test apparatus consist of a square or circular box divided into two halves. The specimen, contained in the box, is subjected to a constant normal load while an increasing horizontal force is applied to one of the sections of the shear box. This force causes a shear failure along the juncture between the box sections of this. The shear force and the normal load are measured directly. The rate of strain is adjusted by the speed of the horizontal force applied. The loading unit has V-strips on which the shear box housing rests. The load yoke in these direct shear test apparatus helps counter balance the loading system. The lead screw connected to the shear box housing helps application of shear stress. Direct Shear Test Apparatus comprises of Direct Shear Box assembly for 60mm x 60mm x 25mm thick specimen, Shear Box Housing, Specimen cutter, Loading Unit with a capacity of 8kg/cm2, set of weights to give normal stress of 3kg/cm2, Proving Ring duly calibrated by Nccbm (Govt) of 2.5kN (250kgf) capacity & 2 (Two) Dial Gauges 0.01mm x 25mm travel.

The load yoke with direct and through level system for applying normal load upto 8 kg/cm2 capacity, fixtures for proving ring, brackets for holding consolidation and strain dial gauges are also provided in these direct shear test apparatus.

Plate Bearing Test Apparatus

Plate Bearing Test Apparatus
Plate Bearing Test Apparatus
Item code: ESTE-100

We are engaged in manufacturing and supplying Plate Bearing Test Apparatus, which is used for estimating the bearing capacity of shallow foundations in situ and for the design of flexible pavement. This test is a standard technique fro determining bearing capacity of soils and is used in agriculture, defense, education, geophysical/ seismology, irrigation and mining industry.
Dynamic Cone Penetrometer (DCP) It is used for rapid in-situ measurement of the structural properties of existing road pavement constructed with unbound materials.The unit incorporates an 8 Kg weight having a drop of 575 mm, fitted to end of the shaft is a 20 mm diameter cone. With the standard DCP measurements can be made down to a depth of approximately 850 mm.Reading are taken after a set number of blows, changing the number according to the strength of layer being penetrated. For good granular bases,readings every 5-10 blows are satisfactory, but for weaker sub-base layers and sub grades, readings every 1-2 blows may be appropriate.

The DCP requires Three operators, one to hold the instrument in a vertical position, one to raise the hammer and let it fall and one to record the results. A typical test takes only a few minutes, providing a very efficient method of obtaining information, which would otherwise require the excavation of test pits. Where pavement layers have different strengths, boundaries can be identified and layer thickness determined.Supplied complete in a nice Wooden Carrying Case.
