Session-5
Special Vehicles
Embedded Files
•Automobile technology has several other applications also. We shall now get acquainted with some of these special applications.
•You would have all travelled by a Train. Railway locomotive is basically a type of automobile.
Steam Locomotive
Electric Train
•In the beginning trains were pulled by locomotives which were powered by steam. Now a days, most rail engines run on diesel fuel or electricity.
•In India, train is a very important means of transportation of goods and passengers. As you know that, a train cannot run on roads but runs on a railway track.
Lifters
•Many of you must have also seen big machines which have long extended arms for reaching high rise buildings or top of electric poles.
•These are mounted on an automobile and the complete machine is called a Crane.
•Some time you may have seen traffic police using a crane to lift cars which are wrongly parked.
•Another interesting application of an automobile is the Fork Lift. A fork lift is used mostly in factories and in large warehouses for carrying components and goods within the premises.
Tankers
•When liquids like water, milk, oil, petrol, diesel etc. are required to be transported to long distances, it is done with the help of Tankers.
•These tankers have very big cylinders mounted horizontally on the chassis of a specially built automobile.
•Sometime, you may have seen the sign “inflammable material” on the tankers that carry volatile fluids like petrol & diesel or gas.
•This warning is to caution people on the road that they should not bring any ignited object like match stick or fire crackers near the tanker.
•This is because petrol & diesel can catch fire very easily. It may be noted that sometimes these tankers are also mounted on railway trains.
