Those who are in construction business would know very well that there are three major types of construction machines used for constructing buildings, roads, dams, bridges and the likes. These are earthwork machinery like excavators, dozers and loaders etc; roadwork machinery like road paver, chip spreaders, and compactor etc; and lifting machinery like cranes. Here in this article, you will come across the most popular and most widely used construction machines names and pictures with short descriptions about them.
Excavators, Dozer, Loaders – Construction Machines
These three are perhaps the moct common construction machinery- excavators, dozers (bulldozer is the most famous name) and loaders.
Excavators- Excavators are the heavy construction and engineering machines that are used for digging and moving large objects on construction sites. Used heavily for making roads, buildings, highways, skyscrapers etc. excavators are indispensable for any project.
Dozer- A dozer is also a heavy equipment used to clear and grade land. These machines have continuous treads and a broad hydraulic blade in their front portion and are classified functionally on the basis of types of blades in a dozer. The two most popular dozers are the bulldozers and the scrape dozers.
Loader- Loaders, as the name suggests, are used on building sites to upload sand, debris, dirt and mud into other vehicles. Their end aim is to clear rubble and digging materials on the sites.
Chip Spreader, Road Paver, Compactor- Road Machines
While the excavators, dozers, and loaders can be seen on any construction site, there are certain specific machines that are only used while making roads.
Chip Spreader- This self-propelled road machine is used for pre-coated chipping surface treatments. It is also used in repairing works. Stone chipping gives quality and durability to roads and chip spreader is the main equipment used for this.
Paver- Also called road paving machine, it is used for laying pavement. Screed, tractor and lorry are its main component parts. It gets the material from lorry and places it in correct dimensions onto the prepared surface forming a mat like structure. This mat is then compacted by roadrollers.
Compactor- Te compactors reduce the size of waste materials through compaction and are found in different shapes, sizes and configuration. Plate compactors, vibratory compactors, sheeps foot compactors, steel rollers compactors with rubber tyres, etc. are some of the popular types of this construction machinery.
Cranes- Lifting Machines
Cranes are also an indispensable equipment for constructing purposes. These are huge tower like machines having provisions for lifting and lowering materials. They are operated by cab operator or with the help of infrared or radio signals. There are many types of lifting cranes such as tracked cranes, vehicle cranes or the truck mounted cranes and crawler cranes.
