Rotary geared limit switch grls is used to trip motor supply when the moving loads reach the extreme end positions of working zone. the driving motion is transmitted by worm gear through worm shaft. the rotations and movements are transmitted to switches by adjustable cams. complying to IEC/EN 60947-5-1, IEC/EN 60529, IES 60060-2-78 IEC 60068-2-30.

Applications-
A rotary geared limit switch are suitable for use on reversing drivs such as hoists, winches rolling mills and various other mechanisms used in steel plants such as coke even, feeding oven machinery etc.

Weight operated limit switches are used on control/power circuit of reversing drives so as to limit their rotation/movement with in a predetermined position. complying to IEC/EN 60947-5-1, IEC/EN 60529, IEC 60068-2-78, IEC 60068-2-30. 

Operation-
When the snatch block of the crane reaches its top position the snatch boxes pushes a plate which is hanging from one end of the lever of the limit switches. due to the weight placed on the other end of the lever, this lever is pushed up. when the lever is pushed up the shaft to which this lever is connected rotates there by rotating the cams which eventually open the contacts.

The anti-collision system is a safety device to avoid collision of two electric overhead travelling cranes on the same bay. the system works on the principle of retro-reflective infrared waves.
The system comprises of an emitter cum receiver module and a reflector. the emitter continously emits infrared back to the receiver end of the system which activates an alarm signal to an stops/reduce the speed of the crane. if two cranes are away from each other the reflected waves will not reach the sensor and the cranes operate normally.
The advanced digital anti-collision system incorporates a micro-controller based circuit for taking digital inputs for easy range setting and gives an accurate cut-off range to the device.two sets of anti-collision systems are required for collision avoidance between the two cranes.
