The construction business based on
three important M's: material,
machine and men. Few years ago, all the tasks of excavating were done by humans
because at that time, we didn't have technological facilities. But with the consistent
improvements in technology, the field of construction has also modified. A vast
range of machines have taken the work of digging from humans. Many of the tasks
are done by these latest construction machines. Invention of excavator is one
the blessing in construction industry.
Excavator is a heavy construction
machine, which is used to move the land or any other heavy stuff from earth. It
is also used to scoop out a hole on the ground and afterword the soil from that
location is also transferred to other place with this machine. To do that task,
it has several parts, which helps to make the task of construction easier.
At the beginning, it was used simply
for digging hole but as the time passed, it is started using for some other
works also like digging of ditches, forestry jobs, mining, elevating and
placing of heavy materials and several others.
In the market, both new and second
hand excavators are available with different prices based on their working
capability and condition. There are two types of excavators available in the
market, one is wheeled excavator and the other is crawler excavator. Used
crawler excavators and used wheeled excavators are easier and affordable to
buy than the new ones.
