Construction excavators, simply known as excavators are well-known heavy construction equipment. They are primarily used for diggers and therefore, also called ‘diggers’. Although for all kinds of detailed information, I would advise you to visit a reputed Hitachi excavator dealer. But for basic understanding, read ahead.

 

What do they structurally consist of?

An excavator primarily consists of a ‘boom’, a ‘bucket’ and a ‘house’.

Attachment

It is a loose term used to label the main functional part of the excavator. Sometimes it is bucket used to pick up heavy earth, other times it is a claw used for digging. Thumbs, grapples, compactions can also be used in the place of the bucket. A general-purpose bucket or GP is generally a smaller, stronger bucket. It has hardened side cutters or teeth. It is generally used to break through hard ground and rocks. The choice of the type of attachment depends on the purpose and the industry where it is being used.

Boom

Boom is the stick that attaches the bucket to the room.it works as an arm. This stick provides the digging movement which is needed to pull the bucket or the claw through the ground. The stick length may vary, depending on the type of work it is required to perform. When it needs to dig deep yet not loose ground, it requires a longer stick. On the other hand, when you need a lot of break-out power, you use a shorter stick. Most common is a mono stick but there are telescopic sticks too.

House

The last main part which completes the whole picture is the house. This is where the operator sits and controls the whole machine. It sits in a pivot point on top of the undercarriage. It can rotate 360 degrees as and when required. Modern construction excavators have sealed cabins. This is to prevent dust and noise from getting in.

Uses of a Construction Excavator

Construction excavators are commonly used in both large scale and small scale construction. Some of its uses are listed as follows:

  • It can be used for digging of trenches, holes and even foundations.
  • Large excavators are used for demolition.
  • Excavators are commonly used for general gradation and landscaping.
  • It is also used in the forests for mulching.
  • Large diggers are used for large construction while compact ones are used for small scale construction.

  • Hydraulic cutters, claws and breaker attachments are used for demolition. The EX 210 construction Excavator by Tata Hitachi has one of the highest-rated hydraulic excavators in India. You can find one in one of many Tata Hitachi ex 210 LC Super Plus dealers in Jharkhand.

  • It can also be used for river dredging.

Construction excavators are one of the most widely used heavy construction machinery. Various Tata Hitachi dealers across India sell world-class construction Excavators which gives high performance. One should check them out before deciding on purchasing them.
