- / *A/5* * 7 8• Initially some concepts were

developed and the gate,basically the automatic gateswhich were developed were ofusing huger amount of power.

The gear motors were usedand they were of high powerconsuming.

• Some of them using a powerof high source and it seemedimpossible to operate themwithout the availability ofpower. And as we know thatthe power is not a continuoussource and it can beunavailable at any time so itwas di cult to run o theautomatic gates without the

ower.

• Some of the newer models ofthe gates make use of thesensors and these sensors areeven not in pro table andacceptable range of the

pockets of each and every user• The function of these sensors isto sense the presence of anyob!ect and transmit the signalto the receiver present in thesliding gates and due to which

the gate is opened and closedaccordingly. The sensorsperforming such type of worksare pro"imity sensors.

- / *A/5* * 7 8• There are many companies

which are manufacturing suchtypes of automatic slidinggates that are completelydependent on the continuous

power supply. Some of themare #rimetech Automation, Technocrats Security System#rivate $imited, %odre!Security &'uipments.

• (ut the only drawback ofthese companies production isthat the automatic slidinggates they manufacture aremaking use of electricity andcan)t be run without theavailability of power. (esidesthis these gates are also nota ordable b ever user.

• *ence after heading towardsthese information there arise aneed of constructing such agate which does not make useof any electric power and

which is fully automatic.• So considering all the above

drawbacks, we decided togenerate a new concept ofmanufacturing the automaticsliding gates that does notmake any use of electricpower and are utterlyautomatic, known asAutomatic +echanical Sliding%ate

Spur gears are the most common type of gears. They have straight teeth, and are mounted onparallel shafts. Sometimes, many spur gears areused at once to create very large gear reductions.

Spur gears are used in many devices like theelectric screwdriver , dancing monster ,oscillating sprinkler , windup alarm clock ,washing machine and clothes dryer . (ut you

A crank is an arm attached at right angles to arotating shaft by which reciprocating motion isimparted to or received from the shaft.

It is used to convert circular motion into
