Railway Signalling Products

Railway signalling is a complex and fascinating subject. We are a main association occupied with offering our customers a top nature of Railway Signaling Products. Railway signalling products  are tough, solid and offer smooth operation for a more drawn out term. In addition to this, we ensure that this raw material is stringently tested at our end to negate any kind of defect so as to offer best of Railway signalling products. Railway signalling is very important to prevent trains taking conflicting routes. Railway signalling maintains a safe separation distance between trains. Railway signalling protects trains from driver malfunction (incapacity / inattention / misjudgment). Railway signalling ensures trains do not exceed their permitted speed.  We design and manufacture the railway signalling system essential for safety train operation. Railway signalling is one of the most important components of the many which make up a railway system and we manufacture Railway signalling prod to meet that system. Train movement safety depends on railway signalling  and the control and management of trains depends on them.

ELECTRIC LIFTING BARRIER

ELECTRIC LIFTING BARRIER WITH HAND GENERATOR BACK UP AND MOTORIZED BOOM LOCKING ARRANGEMENT

Electrically operated Railway electric Lifting Barriers ensure an effective & efficient traffic control at Railway Crossing. Our PANEL OPERATED RAILWAY ELECTRIC LIFTING BARRIERS (Model: GSM -1307) requiring negligible maintenance, are ideally suitable for all such installation. Railway electric lifting barriers have been specially designed to suit Railway Operating conditions.

However, for locations were reliable electrical power is not available. We have developed special ELECTRICAL LIFTING BARRIERS WITH HAND GENERATOR BACK UP (Model: GSM-1702) , which are suitable for all locations. When power supply is available, these barriers can be operated as railway electric lifting barriers by using the push buttons & controls provided on the generator casing door. When power fails, the winch of the hand generator is rotated like a conventional winch type barriers and this rotation develops the electrical power to operate the barrier motors.

Railway electric lifting barriers are reliable and its working capacity is high. Since operating time of railway electric lifting barriers is less, opening and closing is prompt as well as damage of boom also reduces due to heavy road traffic. Railway electric lifting barriers requires less maintenance. Railway electric lifting barriers are comparatively safe and there is no chance of outside interference. In case of power failure, railway electric lifting barriers can be operated with the help of crank handle. Crank handling of railway electric lifting barriers is easy because its counter weight is less and balanced.

BRUSH LESS DC MOTOR FOR RAILWAY CARRIAGE FANS

A brush less DC motor is a permanent magnet synchronous electric motor which is driven by direct current (DC) electricity and it accomplishes electronically controlled commutation system (commutation is the process of producing rotational torque in the motor by changing phase currents through it at appropriate times) instead of a mechanically commutation system. Brush less DC motor is also referred as trapezoidal permanent magnet motors. Brush less DC motor is an indispensable part of modern drive technology, most commonly employed for actuating drives, machine tools, electric propulsion, robotics, computer peripherals and also for electrical power generation.

Brush less DC motor  has no mechanical commutator and associated problems. Brush less DC motor is highly efficient  due to the use of permanent magnet rotor. High speed of operation even in loaded and unloaded conditions due to the absence of brushes that limits the speed. Brush less DC motor has smaller motor geometry and is lighter in weight than both brushed type DC and induction AC motors. Brushless DC motor has long life as no inspection and maintenance is required for commutator system. Brush less dc motor has higher dynamic response due to low inertia and carrying windings in the stator. It has Less electromagnetic interference. Brush less DC motor works with  low noise due to absence of brushes.
