An excavator is heavy construction machinery with versatile uses that is a crucial part of construction and mining projects. The primary function of an excavator is digging soil and rocks. Apart from that, the excavator is also used for demolition and cutting operations on-site. The excavator operates on a hydraulic system and is controlled by an operator from the cabin, popularly known as the ‘house’. Excavators are expensive machines and come loaded with features. Several special attachments available for excavators enable them to carry out other tasks besides excavation. 

Investing in an excavator, though costly, saves construction companies hours of manpower and allows them a quicker turnaround time for their projects. Many types of excavators are available in the market since the construction requirements vary according to the terrain. Choosing the correct type of excavator for a construction project ensures maximum operational efficiency. The basic components of an excavator are a boom, arm, bucket and cabin. The undercarriage located below the cabin supports the tracks or wheels that excavator uses for its mobility. 

Here are the different types of excavators you can see on a construction site:

1.Standard Excavator

The standard excavator, popularly known as the crawler or hydraulic excavator, has a boom, stick, and bucket in front of the machine. The bucket arm extends and lowers through hydraulic power to excavate soil or other materials and can then retract towards the machine to lift the materials. The operator cabin can rotate in full 360 degrees, allowing the operator to dig, move, and dump things conveniently. 

2.Wheeled Excavator

Wheeled excavators are general-purpose excavators used for earthwork, utility work, construction site projects, street maintenance, etc. These excavators have a high ground clearance and are equipped with advanced controls that make them easy to maneuver in confined spaces. As their name suggests, they are wheeled rather than tracked for higher mobility and can be transported from one site to another by road. Wheeled excavators are preferred for construction sites in urban or semi-urban areas. 

3.Mini-excavators

A mini-excavator is a general-purpose excavator with a high-performance output but a short swing radius superstructure which is beneficial in urban and confined areas. There are 2 types of mini excavators, one with a conventional tail swing and another with a zero tail swing. Mini-excavators have several special attachments available in the market, making them versatile pieces of machinery on a construction site. 

4.Long-reach Excavator

A long-reach excavator consists of a giant boom and arm that offer an extended working range for performing tasks such as deep trenching, well digging, canal cleaning and underwater digging in places that are hard to reach. Los Angeles motor grader deals are the preferred choice for demolition projects and over-water body applications.

5.Backhoe Excavator (Backhoe Loader)

A backhoe excavator is a commonly seen excavator on any construction site. It resembles a farming tractor with a bucket on the front side for digging and a backhoe on the back for loading- unloading, also termed as Backhoe Loader. Backhoe excavators are versatile and are popularly known as multi-purpose machines. They can handle every task from earthmoving to landscaping. Backhoes are also used on quarry and mining sites. The only drawback of a backhoe excavator is that it cannot rotate 360 degrees and require space to operate. 

6.Dragline Excavator

Dragline excavators are heavy-duty machines, usually reserved for large-scale sites for activities like strip-mining and canal dredging. They use a bucket system to excavate materials by dragging the bucket on the material’s surface using chains and wire ropes. 

Conclusion

Excavators are versatile construction equipment. High-quality excavators improve the turnaround time of any construction project drastically. They also save several hours of manpower due to special attachments that enable them to carry out tasks other than excavation. Hyundai Construction Equipment is one of the India’s most reputable manufacturer of all types of excavators. They have a vast distribution network, making purchasing spare parts, special attachments, and maintenance convenient regardless of the project location. Their excavators are fuel-efficient and deliver high output by consuming less fuel and keeping the operational costs in check.
