In order to merge two cities or places that is divided by a huge mass of water, we make bridges. Bridges that are strong enough to carry the load of heavy vehicles and cars all running at the same time over it. In order to build something that needs to be so strong, one can easily imagine the kind of heavy equipment that were used to construct such a bridge. The kind of heavy equipment that one can see in a construction or a mining site may not be very useful when it comes to construction of bridges over the water but if we are building a bridge covering a small area that has more of land, then the utility of equipment like backhoe loaders or an excavator becomes essential.
Building a bridge requires deep study of the location and skilled men who can execute the work. An operator who has been working all his life operating machines in a construction site may not find this work as his cup of tea and may probably not even understand how to go ahead with a given task. It is because the kind of work he has been doing all his life is entirely different from the work that has been assigned to him.
Utility of an excavator:-
Heavy equipment like an excavator are ideally used for building bridges that does not have a huge water body beneath and it needs certain degree of excavation to be done. Excavators are usually required for building bridges. Simultaneously, it has the capability to pull out the dirt from one place and put it on the truck. Though an excavator may not be required while building bridges over a huge water body or perhaps its use is limited during the initial phase of the construction and then it is replaced by other heavy equipments.
Bulldozer is needed to level the roads:-
A bulldozer is primarily required at the time of building roads on the bridge. There are used to level the roads over the bridge. The roll of a bulldozer is also quite limited and not used extensively during the construction of a bridge.
Heavy crane bridge building machine:-
In order to build big bridges, you require huge cranes that will help to put the slabs on the face of the pillars. It is unimaginable to place those heavy slabs without the involvement of a heavy crane. These cranes are initially used to give a structure to the bridge and once the structure is formed, the slabs are placed over it with the help of these cranes. Unlike an excavator or a bulldozer which may have limited use, these cranes are extensively used during the construction of big or small bridges.
Since the making of two bridges are not the same, crane manufacturing companies have come up with different types of cranes required for the construction. Each type of crane is meant for constructing a specific kind of bridge. They comes in different shape and sizes and it varies depending upon the sort of bridge that needs to be constructed.
