Construction Machinery: Humans are curious creatures and have been constructing and engineering structures for thousands of years. As time has passed, our species has become more and more competent, with advancements in construction science being a key contributor to our societal progression. This sentiment is reflected in our naming conventions for the periods of times which have past. For example, first came the Stone Age, then the Copper, Bronze and Iron Ages. As each new Age gained access to more powerful material and methods, so too did our tools, structures and weapons become more powerful.
Eventually, the materials and methods were adept enough to allow the development of construction equipment and machinery. In Ancient Rome and Greece, waterwheels would be used to harness the tremendous power in nature; and cranes could be used to displace weights that no humans could dream of lifting by hand. These innovations were followed with the invention of the portable steam engine, which was a main contributor to the great increase in efficiency of the agriculture industry. The steam engine was further improved upon, until finally petrol and diesel engines were made – which opened up a world to power almost any machine imaginable.
Construction Machinery:
In the current construction industry, the following are some of the mostly commonly used machines and equipment:
1. Excavator
This machine is usually used as the core machine in the crucial first stage of any construction project: excavation. Excavation is important as it is necessary to setup the building structure with strong foundations, while also providing a stable surface for future construction operations. An excavator machine is equipped with a large “bucket”, which is used by an operator to dig and relocate large chunks of the Earth quickly and efficiently.
2. Tower Cranes
This machine is the core in the construction of taller buildings and skyscrapers. They are usually fixed onto the ground to a concrete pad to improve stability and greatly reduce the risk any disaster. The crane then uses cables and engines to gracefully hoist large amounts of materials, tools and equipment to the very high elevations that they are needed at. Without these machines, towering skyscrapers would likely not exist.
3. Bulldozers
This machine can be used for shallow excavations and ground levelling. They are made to be extra powerful, so that they are able to quickly push tremendous amounts of materials; such that they able to clear and clean construction areas to create an optimal environment for efficient building. Most bulldozers have tracks instead of wheels – similar to that of an army tank – so that they able to much better distribute their weight and therefore, perform much better on any soft or sloped surfaces.
