It is used for compacting concrete cubes and cylinders.

Specifications: Sizes: 75cmx75cm 100cmx100cm. To carry out a load of 140kg.  The unit 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 form walking off the table during vibration. A cross arm adjustable on a vertical rod at the centre 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 Lesley 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 440 Volts, 3 phase, 50 cycles, A.C.Supply.

Concrete Moulds are easily cast by using a tamping bar or a vibrating table.  However air trapped in cement mortar paste can not be thus removed while casting cement mortar moulds.  Easy method is to impart greater 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 centre of gravity of the assembly is brought to the centre 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 a 7.06cm cube mould and loose base plate, a time switch 0-5mins x 1 min and certificate of vibration.

The Telescopic Leveling Staff is a professional-grade tool designed for precision in land surveying, construction, and leveling applications. Constructed from durable yet lightweight aluminum or fiberglass, this staff is built to withstand tough field conditions while ensuring ease of use and portability.

Available in various lengths—from 4 to 8 meters, with the 6-meter variant being the most commonly used—this leveling staff consists of multiple telescoping sections (typically 5 or 6) that extend smoothly and lock securely using push-button mechanisms. When not in use, the sections collapse neatly into a compact form, making transport and storage convenient.

The staff features high-contrast, easy-to-read graduations marked in meters, decimeters, centimeters, and occasionally millimeters, enabling high-accuracy readings during fieldwork. The precision markings and rigid structure make it an ideal companion for both manual and digital leveling instruments.

• Lightweight and weather-resistant material (aluminum/fiberglass)

• Telescoping design with secure locking mechanism

• Clearly printed high-contrast metric graduations

• Compatible with auto-levels, laser levels, and total stations

• Easily portable and storable due to collapsible design

• Ideal for indoor and outdoor surveying work

Motorized ASTM: D 1559- T –62.
Generally the test is applicable to hot mix designs using bitumen and aggregates uptoa maximum size of 25mm. In this method, the resistance to plastic deformation of
cylindrical specimen of bituminous mixture is measured when the same is loaded at periphery at 5 cm per min. This test procedure is used in designing and  evaluating bituminous paving mixes. The test procedure is extensively used in routine test programmers for paving jobs. There are two major features of the Marshall method of designing mixes namely, a) density – voids analysis b) Stability – flow tests. The marshall stability of mix is defined as a maximum load carried by a compacted specimen at a standard test temperature of 60oC. The flow value is deformation the marshall test specimen under goes during the loading upto the maximum load, 0.25 mm units. In this test and attempt is made to determine optimum binder content for the type of aggregate mix and traffic intensity.

The apparatus consists of: 1) A loading unit motorized, capacity 5000kgf with two telescopic pillars and an adjustable cross head.Limit switches are fitted inside to control upward or downward movement of the pillars. On-off reversing switch and indicator lamps are on the front side while a hand wheel to manually move the pillars is on the right. The load frame Standard Accessories: Marshal Mould:3 Nos, Marshal Rammer:2 Nos, Pedestal :1 Nos, Braking Head:1 Nos.

Used for the determination of bitumen percentage in bituminous mixtures. It consists of a removable, precision machined aluminum rotor bowl (accessory 1500 or 3000 g capacity), housed in a cylindrical aluminum box.
