Description of excavator:

 

The two main sections of an excavator are the undercarriage and the house. The undercarriage includes the blade (if fitted), tracks, track frame, and final drives, which have a hydraulic motor and gearing providing the drive to the individual tracks, and the house includes the operator cab, counterweight, engine, fuel and hydraulic oil tanks. The house attaches to the undercarriage by way of a center pin. High pressure oil is supplied to the tracks' hydraulic motors through a hydraulic swivel at the axis of the pin, allowing the machine to slew 360° unhindered.

 

The main boom attaches to the house, and can be one of several different configurations:

Most are mono booms: these have no movement apart from straight up and down.

Some others have a knuckle boom which can also move left and right in line with the machine.

Another option is a hinge at the base of the boom allowing it to hydraulically pivot up to 180° independent to the house; however, this is generally available only to compact excavators.

There are also triple-articulated booms (TAB).

 

Attached to the end of the boom is the stick (or dipper arm). The stick provides the digging force needed to pull the bucket through the ground. The stick length is optional depending whether reach (longer stick) or break-out power (shorter stick) is required.

FAQ of excavator:

Q: What are the main functions of excavators?

A: Excavator is the machine that can excavate the the soil of various types forcefully and then using hydraulic system a hydraulic force is generated and utilizing this force bucket is exchange with some other attachments then excavator can be used for multi-purpose. For exemple pile diver, hydraulic jack hammer etc...

 

Q: What are the main type of excavators?

A: Crawler excavator; Wheel excavator;

 

Q: What is the application of excavators?

A: The excavator has increased the work speed tremendously. It is used extensively in numerous fields, including the following:

•Wood removal in forests

•Normal grading work and landscaping
