Elektromag Devices Private Limited

`ELEKTROMAG - AIRBARGE' Offers a unique Modular System of standard load bearing platforms and containers that float on an air cushion. These Units provide virtually frictionless movement in any direction for loads of any size and weight when powered from a standard shop air supply.

ELEKTROMAG Bevelling Machine is suitable for bevelling of plates, pipes and structures. This preparation of weld edge is required before welding in fabrication workshops, boiler construction equipment ,shipyards, pipeline ,tank, heat exchanger and machinery manufacturers etc.

Vibrators can be mounted on concrete hoppers, providing a heavy steel liner is used. The liner should extend from the discharge opening of the entire side to which the vibrator is to be mounted. The liner should be held down fast and rest on longitudinal ribs welded along the edge of the plate close enough, so material will not be able to seep underneath. At about 1/4 or less of the distance from the discharge to the top of the sloping side a hole should be cut large enough to allow the Vibrator to be mounted directly to the steel liner. Mount same as on steel hopper.

Sheet metal containers in the form of an inverted frustrum of a cone are ideal for providing efficient vibration. The Vibrator should be mounted directly to the hopper face about 1/4 to 1/3 a distance from the discharge to the top. When two units are necessary they should be mounted diamatrically opposite but at a slightly different height and properly phased.

The "ELEKTROMAG" Thrustor is a device which converts electrical energy into linear mechanical force by its smooth, gental thrust.

The high efficiency off these thrustors make them ideal for a wide variety of general industrial applications such as brakes, thrust motions is machine tools,shutter damper operations, safety devices, actuation of levers, closing the electrodes of spot welding machines, for power processes, operating sliding doors, latches, hopper gates, control valves, transfer mechanisms of conveyors etc.The thrustors enable easy installation as they have only to be electrically connected. The thrustors are particularly adapted for those applications where they are to be frequently operated and are unaffected by these heavy duties because of their robust construction and dust exclusion seals for use in dusty atmospheres. The thrustors economise on muscular effort while saving time, money and labour.

The Electro Hydraulic Thrustor consists of a cylinder filled with oil and having a centrifugal pump at the bottom of the cylinder. The centrifugal pump is driven by a 3 phase fractional horse power class `B' insulated, continuously rated rotor and stator. The specially designed radial impeller permits operation of the pump in either direction of rotation. The rotor and stator is mounted on top of the oil cylinder. The Thrustor is suitable for 720 switching operations per hour. Thrustors confirming to IP-55 and adjustable time lag on both up and down stroke can be supplied at extra cost.

The Vibrator should be mounted on the slopping portion of the hopper, opposite the vertical side. It should be 1/4 to 1/3 or less from discharge to top of slopping side (area).

Inclined chutes not steep enough to produce an easy flow of material, are benefited by the use of Vibrator. One Vibrator usually will handle a 10" to 14" length.

The unit should be mounted below the centre, so the lower portion receives the most provision for slight adjustment in both direction, for many times a slight position change will greatly enhance vibration efficiency.

On tubular chutes, the vibrator should be mounted to a flat or channel-shaped plate which in turn, is clamped to the chute by means of "U" bolts.

When using more than on Vibrator on along chutes, mount the first one within 2' of the discharge, the next halfway between first Vibrator and upper end of chute.

What would you do if you had to move a heavy load across your factory? What if your factory was outdoors? What if the load was fragile? What would happen if the load fell?

The most common methods of moving heavy loads across factory floors are cranes, trolleys, belt conveyors, roller conveyors etc. All these methods have their uses - however cranes require that the infrastructure be forced to support the load and in many cases electric power; trolleys on the other hand are economical - the flooring however must be built so as to support the weight of the load. Some trolleys need rails, loading and unloading docks, and other infrastructure. Belt and Roller conveyors are directional.

In the above cases you either have to build support columns and beams to carry the weight of the load or set up a system of trolleys, rails, rollers etc..

Advances in material sciences have now made possible a safer, more reliable, and cheaper method of moving heavy loads - air ! Yes, air! Loads that are fragile wont break, the load cannot fall, and if you lost power the worst that will happen is that the load will "stay put".

All one needs to do to move a heavy load is put it on an cushion of air (called an air cushion - how simple!) - like a hovercraft. The reduced friction allows one to move a 1 Ton load with approximately 1 Kg of force. Remember however, that one still has inertia to work against.

Mount same as above and on the centre line. One Vibrator will vibrate 3 sites of a hopper of this shape, to a degree which is generally sufficient. If additional vibration is required, a second unit can be mounted on the opposite side a different height.

One of the most effective systems for material handling and conveying of bulky and heavy objects, or those requiring delicate handling and precise positioning, is based on creating a thin film of air between the underside of the load and the floor on which it rests. Such systems are called Air Cushion Mobility Systems.

ELEKTROMAG-AEG Vibrator Motors are robust, reliable, highly loadable, quite-running and require no maintenance. Their essential characteristics are :

• Generously dimensioned cylindrical roller bearing, self lubricating maintenance-free, long life expectancy;
• Embedded in high-quality impregnating resin vibration-proof winding, insensitivity to damp and dust;
• Dust-tight and water-tight through a sealing covering with special circular rubber washer;
• Robust terminal board, cast in synthetic resin;
• Reliable starting by means of a high-powered starting torque;
• Quality-tested components, each motor tested under load;
• Permanent and well legible setting marking of the unbalance weights;
• One or two solid lifting lugs;
• Vibration-proof joining through the considerable tensility of the mounting screws;
• Absolutely secure centrifugal mounting; only the inner centrifugal weights are steplessly adjustable, the outer ones cannot even be dislodged through an unintentional loosening, due to the provision of a retaining ring;
• Highly stressed casting of ductile cast iron;
• Universal mounting facilities through an optimum choice and interspacings in the base mounting.

The demand for high quality foundry products and their cost effective production places high demands for furnace charging equipments in melting plants. Though much of the initial head way made in foundry automation was with the mould making process, more important is the meltshop automation. This includes remote furnace charging systems. Automation is mainly thought of as a solution to high labour cost and it certainly can increase workers productivity. However, much more important today is the effect of automation on quality. Another important advantage that automation provides in foundry environment is enhanced safety. For example automation allows foundrymen to work at a safe distance from molten metal or do their jobs behind protective barriers thus reducing injuries from metal splash or furnace eruption. Also where automation exercises monitoring & control functions, it helps prevent accidents related to in-attention or judgement errors.

Elektromag has developed a wide range of slide and guideway wipers for protection of both conventional and hydrostatic guideways

Elektromag's engineering department is now equipped to design and develop slide and guideway wipers for almost any application

The types BA 18 and BA 25 are recommended for those applications where it is ensured that there is no long-term temperature exceeding 100 degree centigrade in the immediate vicinity of the wiper. On account of their small dimensions, they are particularly suited for attachment to guideways which will be equipped additionally with telescopic steel guards, or a concertina type protection, or an articulated apron.

The types BAS 18, BAS 25 and BAS 40 are characterized by a lip protection. They are to be used with preference where the wiper is exposed to direct contact with the falling chips.

Different height dimensions of the light-metal supports make it possible to exchange our wipers against any commercial makes in the market. Attachment can be made with screws upto size M6, without the necessity to have the screw-heads countersunk.

Wooden hoppers do not respond to vibration nearly as well as metal hoppers. Vibration cannot be transmitted around corners to other side or to as great distance. If construction is of planking supported on joists, then same instructions apply as for steel hoppers. Bolt direct to planking and make sure you use a large enough unit. If wooden hopper is lined with metal plate (as with concrete hopper) the Vibrator will be mounted on stilts going through the plate but clearing the wooden planking.

The types SC (standard unit) and SCTA (tandem unit) are metal detecting devices for protection and monitoring. These devices are designed with a specification that makes them suitable for a wide range of applications in areas where material have to be checked in view of metal pollution. Where ever metal pieces in the conveyed material may damage sensitive machinery, the metal detecting devices will prevent expensive repairs and production break-downs.

The devices will not report ferric oxides like magnetite and hematite that are often inclusions in basalt, in builders sand, and especially in slages. Thus the metal detecting devices SC and SCTA will help you to assure the quality of your products and save costs.

The ELEKTROMAG/EAB Walk-through metal detector incorporates the latest technological advances for weapons detection and pilferage prevention.

ELEKTROMAG Cable Drag Chains enable the conveyance of flexible cables/hoses etc. to movable units with maximum reliability.

The ELEKTROMAG cable drag chains are so constructed that they cannot bend below a fixed minimum radius to suit the cable or hose.

ELEKTROMAG cable drag chains are not only used for cable leads but also for hoses conveying gaseous, liquid or pulverised media. Single twisted leads can be conducted close to one another.

Besides the normal horizontal movement, the ELEKTROMAG cable drag chain can be used in vertical, circular or combined horizontal and vertical applications.

ELEKTROMAG Moulded Plastic Cable Drag Chains are a logical addition to the range of the steel Cable Drag Chains which have proved themselves worldwide for over 25 years.

They can be used wherever the required energy input cables/hoses are light, the travel is small and the environmental conditions permit the use of plastics.

The chain links and separating plates for taking the cables/hoses, form a single unit in the ELEKTROMAG Cable Drag Chains. The individual chain links can be connected by a snap connection enabling them to be joined to form a chain of any required length. One of the advantages of this system is that the customer can make up any required length of chain so that stocks can be kept and it is not necessary to place an order for each requirement.

If the cross section of a cable drag chain is too small for the cables, it is possible to divide the cables between a number of chains arranged side by side or opposite to each other.

ELEKTROMAG" Vibrating Feeders provide the most efficient and economical method of conveying bulk materials and, what is more important the simplest and easiest means of controlling the rate of flow or feed.

Vibrating Feeders are extensively used in Iron and Steel works, Collieries Quarries, Gas Works, Mines, Chemicals, Pharmaceuticals, Ceramics, Rubber, Clay and Glass Industries for handling all types of materials - big lumps of ore down to fine chemicals - hot or cold - dry or damp - Capacities from 50 grams to 2000 Tonnes per hour.

Vibrating Feeders protect the belt conveyors from damage by feeding the material onto the belt conveyors from storage hoppers, silos, surge hoppers and dumpers at a controlled rate.

The Biggest Advance in Motor Driven Cable and Hose Reeling for many years

ELEKTROMAG-METOOL have available a complete range of motor driven torque regulator reels. The reels shown in this catalogue are direct reeling units where the cable compartment is mounted directly on the torque regulator.

For those applications where the length and weight of the cable is in excess of the design capability of the direct reeling units, we have the indirectly driven torque regulator reels. With these reels the torque regulator unit powers the reel compartment through a suitably selected transmission.

ELEKTROMAG-METOOL have produced in the TR range a reliable low cost solution to be the problems of reeling long lengths of cable at the high duty cycle rates demanded by today's heavy industry.

ELEKTROMAG-METOOL range is now available for the complete range of cables for lengths from 30 to 1000 meters, for voltages upto 11000 volts.

Among the most versatile forms of conveyors are the Helical Conveyors. They consist of an upright tube around which winds a conveying-path, the cross-section of which can be rectangular or round. They are made of Mild Steel or Stainless Steel. According to the spiral-like arrangement of the conveying path, a long effective distance is acheived. They are driven by electromagnetic or unbalance motors which are mounted in diametrical positions and at a certain angle either at the bottom or at the top of the tube. They produce torsional vibrations. By Micro-projectile movements on the whole conveying path, the product is induced to make its way steadily upwards. According to capacities required, the helical conveyors can be built upto a height of 6 metres. They can be equipped with double conveying paths, so that it will be possible to trnsport two different products at the same time. Depending on the bulk material delivery flows upto 20 M3/h can be acheived.

Well ventilated lowered enclosures on sides along the length, and load bearing members along the depth of adequate strength for free standing and top canopy for protection from rain.

Enclosure protection conforming to IP-00, IP11, IP-23, IP-33, and IP42 or totally enclosed IP-54 construction ore available as per customers requirements.

The detector can be set to any predetermined thresh-hold level and remains perfectly tuned during the search.

Fail-safe Remote Control Infra-Red System the cost effective alternative to pendant cable control

Problems of pendants for hoists and cable control for machinery have become a thing of the past. Now, the highly cost-effective TH-IR/12 BEAMER fail-safe remote control system offers an economical alternative to previous cable-limited controls.

You can forget the inconvenience - and danger - associated with struggling around abstacles with cable control. A crane operator for example may now move freely in his area, controlling the crane remotely from wherever he chosses.

Unrestricted freedom of movement decreases the time to complete the job, benefiting profitability while increasing safety.

The BEAMER has been designed to comply with international safety regulations.

ELEKTROMAG" Stall Torque Motors are used for applications where motors need to be continuously energised at standstill and still provide constant torque e.g. Reeling Drums for cables, hoses, wire ropes etc.

SQUIRREL CAGE Stall Torque Motors are used in applications which involve small payout of cables/hoses.

SLIPRING Stall Torque Motors are used for applications where high thermal losses associated can be dissipated in the externally connected resistances. In addition these have the advantage of possible speed control by switching in and out differing resistance values. Higher torques can be achieved with intermittent duty or with external ventilation.

"ELEKTROMAG" Stall Torque Motors have builtin disc brakes which eliminate the problems of dust clogging encountered in conical brakes.

The motors can be supplied for an operating voltage of 415V/240V 50c/s supply and for ambient temperature upto 60ºC .

These motors can be supplied for horizontal mounting, base mounted (B3 construction) or flange mounted (B5 construction) depending on requirement.

The motors are rated for continuous duty. The motors conform to IP55 protection and are class 'F' insulated.

Small parts conveyors are vibrating conveyors used for discharging, conveying, feeding, dosing and distributing fine-grained bulk materials and large quantities of relatively small parts. Elektromag has been manufacturing these conveyors over the years and leads the field in India.

They are used in many branches of industry, for example in the chemical and synthetic materials industries, food processing, sand, gravel and stone quarries, for small parts assembly mechanisms, in the foodstuffs and luxury food sectors, paper making industry, and in sugar refineries, oil refineries and foundries.
The compact small parts conveyor drives are available in a range of sizes and can be fitted with attachments such as troughs, tubes or rails.

Contactors with rating from 15 Amps to 1500 Amps are available in four
basic types, viz.,Single pole, Double Pole, Triple Pole, and Four Pole
with main contacts open or closed or a mixture of both, as per clients
specification.

Operating coil is 'B' class insulated, D.C. energised working on 2200 Volts
D.C. Other operating voltages can be offered on request. Contactors can also
be offered with a rectifier bridge to take direct supply from an AC source.

The contactor will operate satisfactory on 80% of normal voltage when the
coil is hot and will hold in on 200% of normal voltage. The coil will
withstand 110% of the normal voltage continuously.

Arc chutes are made from special heat resistant material such as syndyano
and are hinged so that they can be lifted for inspection or replacement of
contacts. In the lifted position the arc chutes are self supporting.

Two or more Singal Pole contactors, mounted on a singal base can be
mechanically interlocked in a simple but efficient manner to operate as a
multi-pole contactor. Shaft mounted multi-pole contactors can also be supplied.

A wide range of electrical interlocks by means of Auxiliary Contacts is
available on request at extra price.

Three sizes of stainless feed hoppers are available to suit the range of different small parts conveyors. The volume of the hopper and the diameter of the discharge outlet are determined by the width of the standard trough used. The feed hoppers are adjustable for height and are attached to a special frame. The base-plate of the frame supports the small parts conveyors, thereby forming a single unit (fig. 3). The vertical adjustments makes it easy to regulate the layer height in the trough, which in turn controls the delivery flow. If required, the feed hopper can be supplied with a viabrator which causes the material being conveyed to discharge more easily.

ELEKTROMAG" Electro magnetic Clutches are uses are used where frequent load cycling takes place. Where a motor must be accelerated and decelerated, there is motor heating which reduces the motor life. By installing a Clutch the motor can be operated at its normal speed and the load can be cycled by engaging and disengaging the clutch.

Where rapid cycling is involved, the load requires that the inertia of the system must be overcome. In a directly connected system, motor inertia delays the response of the system. With a clutch installed, only clutch inertia has to be overcome which is considerably lower as compared to that of the motor.

The clutches are ideal for jogging applications as motor tend to get overheated due to frequent stopping and starting to inch a load into position. The Clutch enables the motor to run continuously at constant speed and the clutch can be engaged and disengaged to jog the load. Where a load has to be stopped, one member of the clutch can be kept fixed and the clutch works as a brake to stop the load from rotating on its own inertia. Indexing and positioning is made possible by using a clutch and brake. A clutch enables the load to be brought to position and stopped in that position by means of a brake.
