Pulleys and cables are the material that is main material which is used to design cranes. The main purpose of crane is to lift the material and to lower the material. All construction industries and manufacturing factories use cranes in order to carry hefty material from one place to another. All heavy material and equipment that cannot be pulled by human beings can be taken from one place to another by using cranes. Cranes are usually used in transport industry or in construction industry.
- These all cranes are operated by operator available in cab.
- These cabs are mainly meant for cranes which travel along with it.
- These cranes take hefty material from once place to another by using buttons available there.
- Movement of cranes take place via push button or radio type control.
These cranes were used in Europe in middle age time period. To build cathedrals of Europe cranes was attached to top of wall in order to perform whole construction. It has two large wheels which are present on each side of crane. For making of shipyards and medieval ports these cranes are used.
This crane has mobile platform on which telescopic boom and steel truss is mounted. Boom is placed at the bottom of crane and it can be easily raised and can be lowered by using cables and hydraulic cylinders.
These types of telescopic cranes also uses boom which further consists of tubes. These tubes are present in large number and in the form of one inside the other. Hydraulic mechanism is the mechanism via which operators can easily change the length of boom.
This crane also called as balance crane. These cranes are very beneficial for carrying hefty material to high level. So it is used to construct high buildings.
Truck mounted crane
In rubber tire truck is used which will provide crane high mobility. During hoisting outriggers are used to stabilize the crane.
Rough terrain crane
In this crane four rubber tires are used and it single engine machine. In this engine is placed in undercarriage.
In this articulated arm is attached to trailer and it is powered hydraulically. In this when there is no usage of crane then it turned into small space.
Mainly named as suspended crane and used in factories to carry hefty load.
Cranes are very important part of manufacturing and construction industry. From ages it helped a lot in all construction work.
