Excavators are heavy construction equipment that consist of a boom, bucket, and cab on a rotating platform. All functions are accomplished through hydraulic fluid. Their design evolved from steam shovels. Key manufacturers include JCB India, BEML, L&T Case, L&T Komatsu, and Ingersoll-Rand India. Excavators come in different types and are used for digging, material handling, forestry work, grading, lifting pipes, mining, dredging, and driving piles. They are commonly used in construction, mining, quarries, and other heavy industrial projects.
2. ï‚— Excavators are heavy construction equipment consisting of a
boom, bucket and cab on a rotating platform (known as the
"house"). All movement and functions of the excavator are
accomplished through the use of hydraulic fluid, be it with rams
or motors. Their design is a natural progression from the steam
shovel.

10. Segmentation and target
Major segment- Road construction, mining and quarry
and heavy construction and general construction.
Target- roads and highways, construction sites, and
mass excavation application.
11. Segmentation and target
 20T – construction , infrastructure.
ï‚— 20T up to 33T -are mainly used in quarries, sand
pits and light- duty mining applications.
ï‚— 33T to 50T -range of excavators are primarily
deployed in mining, limestone, granite and marble
quarries and on large hydro electric power
generation projects.
ï‚— 50T -machines are used for large mines.
