BEAM MOULDS
For casting, concrete specimens for flexture tests.
Specifications :
Made of cast iron. The moulds are made of 4 plates assembled together. Each mould is supplied complete with base plate. Faces are machined flat to +-0.2mm. and finished in size to 0.2mm.

CAPPING SET
For correct compressive strength of concrete cylinders, the end surfaces of the specimen must be truly flat. If they are not, using capping compound and a capper, the faces are plastered flat. Capping set can be used for cylindrical specimen like concrete cylinders of cores. They can be used in laboratory or in field.

CAPPING SET (HORIZONTAL)
IS : 516 – 1959, BS 1881, ASTM C 31, C 617.
For 15cm dia x 30cm length cylinders.
Specifications :
The set comprises of a cylinder capper, a cylinder carrier and a ladle.
The cylinder capper consists ofa a base on which two accurately machined plates are mounted vertically. Once plate is firmly fixed and the other one is adjustable horizontally. Two plates are provided with holders for holding the cylinder in position. The holders are split and the bottom half of each holder is fixed firmly and the top half of each is removable and bolted down to the lower half. On the upper parts of the vertical plates ‘V’s are provided for pouring the capping compound. Two spacers are also provided. Complete with cylinder carrier and ladle for molten compound..

CAPPING SET (VERTICAL) IS : 516 - 1959
For capping compression cylinder specimens. This apparatus can be used both in the laboratory and in the field. The specimens capped in this apparatus have plane parrallel faces. Specifications: For cylinders 150mm dia x 300mm long.
Consists of a base with an upright. The upright serves as a guide for positioning the capping plate and the cylinder. The 19mm thick capping plate is machined accurately. There is a racess in the plate for keeping the molten capping compound and to position cylinder. Complete with cylinder carrier and ladle..

VIBRATING TABLE
The Vibrating Table is used for compacting concrete cubes and cylinders.
Specifications:It is designed to carry a load of 140kg. The apparatus consists of a motor fitted with a variable pitch pulley housed in a cabinet. The vibrator clamped to imparted by means of off-balance masses rotating on a shalf of a vibrator clamped to the underside of the table top. The table top is 50cm x 50cm. and has stops along its edges to prevent moulds from walking of the table during vibration. A cross arm adjustable on a vertical rod at the center of the table is provided to hold the moulds while operating the table. The variable pitch pulley arrangement permits the frequency to be varied steplessly between a maximum of 3600 vibrations down to 2600 vibration per minute. A speed regulation handle is provided for increasing or decreasing the frequency. A switch is provided for starting the motor. suitable for operation on 440 volts, 3 phase, 50 cycles, A.C.Supply.
Note: Vibrating Tables of table top size 75cm x 75cm as well as 100cm x 100cm are also available.

VIBRATING MACHINE
(Also called MOULDE VIBRATOR OR MORTAR CUBE VIBRATOR )
IS. 4031 – 1968, IS : 1344 – 1959, BS : 12.
Concrete moulds are easily cast by using a tamping bar or a vibrating table. However air trapped in coment mortar paste can not be thus removed while casting cement mortar moulds. Easy method is to impart greater vibratin of lesser amplitude to the mould while casting. This is achieved in a Vibrating Machine.
Viberating Machine is used for the preparation of mortar cubes for the determination of compression strength of ordinary and rapit hardening Portland cement, low heat Portland cement, Portland bleast 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 forur 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 entire 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 cubs mould with loose base plate, a time switch 0-5mins x 1min and certificate of vibration from a standard laboratory.
Spares: Set of Springs, Belt and Belt guard..

HYDRAULIC JACK (HAND OPERATED) REMOTE TYPE
For applying loads for various tests in field or laboratory. Hydraulic Jack hand operated with seprate pumping units. These Jacks are portable and available in various capacities. The pumping unit is connected to the hydraulic jack by means of a flexible connecting pipe 2 meter long. The jack is fitted with lifting handles for easy transportation. The approximate lift of the ram is 90 to 120mm, the pumping unit is a single plunger type with detachable handle. The unit is fixed on a Channeled base which is fitted with lifting handles. A pressure release valve is provided on the pumping unit. The load is indicated on a 15cm dial hydraulic pressure gauge of appropriate capacity which can be detached from the pump when not in use. The least count of the calibrated dial will be according to the capacity of the gauge (Normally 100 divisions for full capacity)

JMT - 550
INTEGRAL TYPE HYDRAULIC JACKS CAPACITY 30,50 & 100 KN
These are hydraulic jacks with integral pumping unit. The hydraulic pressure gauge is of 15cm dial mounted on the side of hydraulic jack. A detachable lever is provided to operate the pump. Lift of the ram is 95 to 100mm. Face of the ram is flat..
Note: Hydraulic jacks of 1000 KN & 5000KN capacity can be supplied with two speed pumping units. These jacks have lift of approximately 200mm.
