Concrete moulds are easily cast by using a tamping bar or a vibrating table. However air trapped in cement mortal paste can not be thus removed while casting cement mortal moulds. Easy method is to impart greater vibration of lesser amplitude to the mould while casting. This is achieved in a vibrating machine. Vibration of lesser amplitude to the mould while casting. This is achieved in a Vibrating Machine. Vibrating Machine is used for the preparation of mortar cubes for the determination of compression strength of ordinary and rapid hardening Portland cement, Low heat Portland cement, Portland blast furnace cement and high alumina cements.

Specifications: The machine consists of a vibrating frame assembly and an electric motor mounted on a sturdy base. The complete frame assembly consists of a vice to hold a 7.06cm cube mould and two studs threaded at top and a hopper to feed the sample in the mould. This assembly is supported on four springs and has an in built rotating shaft which rotates eccentrically and thus imparts vibrations to the entire frame. A balance weight is an integral bottom part of the frame. The center of gravity of the assembly is brought to the center of the eccentric shaft or within a distance of 25mm below it. The electric motor drives the shaft of the frame and thus imparts required vibrations to the mould. The frequency of vibration is 12000+/-400 vibration per minute. Supplied complete with on 7.06cm cube mould with loose base plate a time switch 0- 5minsx1min and certificate of vibration from a standard Laboratory.

Manufactures a wide ranges of hydraulic pumping units. These are hand operated of electrically operated. The pumping units are suitable for applying load is a load frame of applying pressure to hydraulic jacks. The special features of pumping units is that the plungers of the pump have tolerances and no seals are used in the units and special type of non return valves as against traditonalball valves are used, which gives much longer trouble free service. Electrical Pumping Units work on 230Volts A.C. or 440 volts A.C.3 phase depending upon their capacity and these can be operated by hand in case of power failure. The front panel accommodate pressure gauge, on/off switch, slow fast lever to control the rate of loading and indicator lamps. Further in electrical units a micro switch fitted in the pressure gauge and a connected to a relay automatically cuts of the power supply to the unit when gauge capacity is reached. A dummy pointer to record maximum load applied is fitted on the cover glass. In hand operated pumping units, two plungers of different diameter are used. The plunger with larger diameter pumps oil at faster rage and is used for initial loading. Further load is easily applied by the second pump which has a smaller diameter plunger, The lever for operation of the pump is sufficiently long to minimize efforts and these units are suitable for site use.

Strength of Concrete is a very important aspect during construction. Strength of concrete is obtained by crushing the specimen form of cubes of cylinders. Concrete is carefully designed for a particular compressive strength by the Engineers and specimen is tested by applying load in a compression Testing Machine. Manufactures a range of Compression Testing Machine from 10 Tonnes to 200 Tonnes in different models. Portable models are very convenient and useful for site use where carrying frequently the specimens for testing in a standard Laboratory is inconvenient and uneconomical. With special attachment the machines can also be use for bricks hallow or solid concrete blocks, using appropriate capacity machine In general a Compression Testing Machine consists of a Load Frame with suitable platens and a Pumping Unit with Pressure Gauge, either hand operated or electrically-cum-hand operated. Load Frame and Pumping unit are connected by pressure pipes.
