Hydraulic & Engineering Instrument

Our wide range of Brazilian test apparatus are used for indirect measurement of tensile strength of rocks. These meets the requirements of IS:10082-1982 for use with ‘NX’ size core samples. Further, our equipment comprises of the following:

• Loading frame with 100kN capacity, having a base and a cross head joined together with two solid pillars with nuts. At the top, the pillars have long threads for height adjustment and on the base, a 100kN hydraulic jack is centrally fixed between the pillars. This jack has an integral pumping unit and oil reservoir.
• A 100kn capacity pressure gauge is fixed to the jack for indicating the load on the specimen and also an operating handle is provided with the jack.
• Brazilian Attachment for ‘NX’ core size specimen with thickness half the diameter with two loading jaws. The lower jaw has two guide pins fixed with it and the upper jaw has two guide holes for the guide rods to hold the two jaws aligned. Further, the upper jaw has a spherical seating on the upper side to seat a ball for self-alignment and supplied complete with the steel ball.

Our range of core drilling machines are of light weight, versatile and easy to operate. These are designed with a tubular frame mounted on two pneumatic tyres. In addition to this, we also provide a hook in the front side of the frame to be towed behind a jeep and the tyres have been so placed that the total machine is balanced.
Further, the main gear box gives a manual feed of 600 mm can be rotated in any direction that is 0-360o for a convenient angle of drilling. It is powered by 4.8 H.P. diesel engine and suitable for taking cores up to the diameter of 150 mm and depth more than 4-5 meters with help of extension rods and bits.

We offer digital rock shear, which comprises of two controllers, hydraulic power pack with tandem pump to feed two actuators. These are available in the sizes of 300 mm x 300 mm x 450 mm, which can contain maximum rock specimens of 300 x 300 x 150 mm that are naturally or artificially jointed in any shape and form.
Further, the parameters like normal load and shearing load on strain basis or stress basis are controlled through the computer. In addition, on line graphical presentation is shown on the monitor. Moreover, after completion of the tests, our range helps to plot the following graphs on the window operated software.

• Shear force Vs horizontal displacement.
• Horizontal displacement Vs vertical displacement.
• Shear stress Vs normal stress.

Our range of mobile drill rig are designed for the exclusive needs of pre-construction geo-technical investigation and post construction quality control and maintenance requirement of the structure. These are light in weight and easily move able on its two pneumatic tire wheels.
Further, the precise hydraulic operation and centralized control panel ensures easy operation and low maintenance of our products. In addition to this, the continuously variable rotation speed and feed rate under constant torque range with least vibration in the unit enables our range to give better core recovery and faster penetration at uniform rate both in soil and rocky strata.
Our products are used in the following organizations:

• Professional Soil/Site Investigating Agencies.
• Consulting Geo-tech Civil Engineers.
• Research Organizations.
• Technical Education Institute.
