Road Construction Machines and Uses for Each

Without the machinery, the construction of different structures, roads, tunnels etc are impossible. Using the construction machines make the work easier, safer and speedier. There are different construction machinery used for carrying out various works. The excavators, loaders and cranes are the most common used road construction and building construction machines. Find below the list of construction machines and the uses for each with the main construction categories. 

Road construction involves designing, building and maintaining pavements and upper layers of transportation routes. Most of the roads surface are constructed with concrete or asphalt. Now coming down to road construction machines, the list goes:

• Milling machine : It helps in removing the surface layer and preparing for construction of new layer.
• Paver : It enables to lay the concrete and makes the layer more even.
• Compactor : A compactor is used for compressing the concrete on the paver.

Types Of Loaders Used In Construction

Loaders are the popular heavy machines, especially used in construction sites for carrying dirt, debris, mud, rocks, sand etc. and dumping these waste materials in to another vehicle or other machines so as to clean the area. This is a popular construction machinery and there are different types of loaders used in construction. The most common types are discussed here in.

Wheel Loader
A wheel loader is basically a front end heavy loading machine. This machine digs the materials from the ground and drag them to the dumping area. The bucket size and operating weights vary in different wheel loaders. There are two basic varieties: tyre mounted or track mounted. The more popular ones being the tyre mounted loader. They are easily movable and fast. The tracked mounted wheel loader is harder on paved roads and other surfaces and hence not very effective to be used in all cases. However they are helpful in loading of sharp edged materials which would otherwise destroy a tyre mount loader. The basic advantage of track loader over wheel loader is the increased traction.

Skid Loader
A skid loader is another variant of loader and often referred as skid steer loader. This type of loader is heavy engine driven machine and has lift arms, in which a number of attachments can be fixed for varied construction applications. There are two basic features that make this loader different from other varieties. A skid loader is very compact. It can turn around in an area irrespective of its length and hence can be used in small space as well. And secondly, the lift arms are attached to the sides of the loader and hence the lifting can be done evenly on both sides. There are two varieties of skid loaders: with rubber track or with 4 wheels.

Skid Loader

Backhoe Loader
Backhoe loader is another popular engineering vehicle used in the construction industry. This is a loader in the body of a tractor, having a bucket or shovel in the front and small backhoe in the back. This is basically small in size and hence preferred to be used in small construction projects.

Classification of Construction Machines As Per Application

It is a common fact that we find a wide variety of construction machines on every construction sites, which make the construction jobs easy, safe and quicker. Depending on the application, construction machines are classified into various categories which we are discussing here.

The construction work can be classified into 3 major groups:

• Earthworks
• Road Works and
• Lifting

Earthworks
Earthworks refer to the construction and engineering works which involve the moving or transfer of large quantities of soil or unformed rock. The two most popular type of construction machines used in earthworks are digging machines and surface digging machines.

Digging Machines: Excavators and Loaders
Excavators are the most popular and widely used types of heavy equipments, which are mainly used for  digging holes and building pits. They are available in different construction variants.  Loaders are another type of digging machines which are very fast compared to excavators. The main purpose of loader is to move loose soil.

Surface Digging Machines: Dozer, Grader, Scraper
The surface digging machines are used to prepare the construction surface by moving and changing the soil. A dozer is an important surface digging machine which pushes soil in and out to create a somewhat flat surface. This flat surface can further be flattened by using graders. The grader as a construction machine is popular as it can do leveling jobs very effectively, creating a smooth surface for construction. This becomes particularly helpful in projects of road construction. Scraper is another type of surface digging machine, used to scrap a thin slice of soil. The scraper further moves the scraped layer of soil material to an area few meters away. Scrapers are most widely used in big earthwork construction sites.

Road Works: Milling Machine, Paver, Compactor
One of common applications of construction machineries is in road works and road construction.  The milling machine in road works is  used to machine solid materials or remove a layer of unwanted material from roads. Widely used for repair jobs, so that a new layer can be created by milling off the destroyed layer.  A paver is an important construction machine used to lay asphalt or concrete on roadways. Compactors are used for compacting concrete or asphalt. Compactors as earthwork  or  road construction machines are used to compress soil and hard materials in construction sites and roads. They press and stabilize the soil for further construction purpose or pave the asphalt or concrete roads to make them smooth and plain roads.

Lifting machinery: Tower Crane, Portal Crane, Cable Crane, Tractor Crane, Truck-Mounted Crane
Lifting machinery as the name suggests refers to the lifting machines used to lift objects in construction sites. There are different types of lifting machines. For example: Tower Cranes are used to lift concrete, steel, large tools and different building materials. They can rise to great heights and are a common machine at any major construction site. Portal cranes  can lift heavy loads and seen mainly on storage sites and and trans-shipment centers. There are cable-operated cranes that are seen at dam construction and other construction sites which have the appearance of a line layout. These cranes can move over huge distances and deep valleys. The tractor cranes can move freely around the construction site. The truck mounted cranes are used for lifting jobs of short duration. Their basic advantage is that these cranes can drive on roads.
