Digital Plate Load Test Apparatus Sigma-034DPL:- This test method is used to estimate the bearing capacity of a soil under field loading conditions for a specific loading plate and depth of embedment. It is also used for load tests of soil and flexible pavement components for use in evaluation and design of airport and highway pavements.

Plate Loading Test Set consists of a 500 kN capacity piston assembly and hydraulic hand pump, pressure transducer, LPI battery operated digital readout unit, 2.4 m long datum bar, 3 pcs. 25 mm travel x 0.01 mm digital dial gauges with dial supports, 300 mm, 450 mm, and 600 mm loading plates.

Slump Test Apparatus Sigma-026ST:- The Slump Test Apparatus is filled with freshly mixed concrete and tamped with a tamping rod in three or four layers. The top of the concrete is leveled off with the top of the slump cone, the cone is lifted vertically up and the slump of the sample is immediately measured. The complete set comprises of a Steel Octagon Base Plate (8 faces) with carrying handle, Graduated Tamping Rod 16mm dia x 600mm long with one bullet end, slump cone having base 200mm, height 300mm fitted with handle.

Specification :

• Slump Cone Downside Diameter: 200 mm
• Slump Cone Tube Height: 300 mm
• Tamper: Dia 16 mm
• Material: Iron

We are specialized in offering Jolting Apparatus for our valuable clients. The Jolting Apparatus is used for making standard rectangular specimens 40 x 40 x 160 mm. We provide the Jolting Apparatus at competitive price range.

The jolting apparatus consists of a rectangular table rigidly connected by two support arms to a spindle at a horizontal distance of 800 mm from the centre of the table. The table can be raised and allowed to fall freely on the stop by a cam, which is connected to a motor and gearbox through a V-belt and pulleys. The cam rotates at a rate of 60 rev/min. A stroke counter fitted with micro-switch is provided which stops the machine after 60 jolted. Locating pips are provided for mounting the mould compartments on the table. The mould surmounted by the hopper can be clamped rigidly to the table. It is supplied with mould and hopper. The Jolting Apparatus is suitable for operation on 230 Volts, single phase, AC supply.

Cube Moulds are available in different sizes and are made according to Indian and British Standards. All moulds are supplied complete with base plate.

Cylindrical Moulds Sigma-024CM:- Moulds for testing concrete Cylindrical Moulds for Compressive Strength Testing are offered in two different sizes. These cylindrical moulds are made of Cast Iron and split into two parts longitudinally. These are supplied complete with a base plate and top plate.

Specification:

• Material: Tungsten Carbide, HSS etc
• Shaping Mode: Punching Mold
• Precision: ±0.002 mm
• Roundness: Within 0.0015 mm
• Concentricity: ±0.002 mm
• Straightness: Within 0.002 mm

Vibrating TableSigma-032VT:-

 VIBRATING TABLE: Introduction:

·         The Vibrating Table is used for compacting concrete cubes and cylinders.

 General Description and Specifications: 

·         It is designed to carry a load of 140 kg.

·         The apparatus consists of a motor fitted with a variable pitch pulley housed in a cabinet.

·         The vibrations are imparted by means of off-balance masses rotating on a shaft 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 off 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 step less between a maximum of 3600 vibrations down to 2600 vibrations 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 220-240 volts, 1 phase, 50 cycles, A.C. supply.

 Note: available Sizes of Vibrating Tables 

·         size 50cm x 50cm

·         size 75cm x 75cm

·         Size 100cm x 100cm.
