How Do Excavators Work?

Feb 15 , 2022

Some construction projects require deep excavation to move large amounts of material, so excavators are needed to perform such work. From sewer, plumbing, and wiring operations to the construction of urban complexes, roads, highways, and paving, excavators are useful for performing high-performance deep work.

This will allow us to obtain the necessary information when choosing a model. A hydraulic excavator is a heavy-duty machine with hydraulic arms of various sizes with blades at the tips, designed to move on wheels or chains, and also has the ability to rotate 360 degrees around its own axis.


Its functions include digging, rotating, moving, loading, shifting, and unloading objects. The machine is commonly used to open up recesses where pipes, drains, and cables will be installed, as well as to excavate foundations or ramps.

A hydraulic excavator is a machine that uses a combination of mechanical, electronic, and hydraulic components to achieve superior performance in mining and construction. Generally, the engine of a hydraulic excavator is a four-stroke diesel engine.


Its mechanical arm is able to combine different tools to work on land, concrete, rock, or steel.

Functions of the excavator operator.


Start the material and load it into the transport unit

When equipped with a hydraulic hammer, it can also perform trenching, load handling, and block removal and destruction.

It can be adapted to different arm ranges, bucket capacities, soft or hard floors.

When very hard, it can contain more wear-resistant parts.

How do I operate an excavator?

What is an excavator used for: Excavators are generally used to start materials such as stones and earth. With the help of its accessories, you can also cut steel, break concrete, drill holes in the ground, make gravel foundations before paving, and crush rock, steel, and concrete.


Excavator training

How an excavator works: To understand the operation of an excavator, we must know that its moving arm consists of two hydraulic cylinders, a bucket, and a moving arm.


This work simulates the movement of the human arm, just like the wrist and elbow. Then we have the engine that works by changing the hydraulic power. In the cabin are the operator’s seat and the controls of the machine. It has some feet that can be of normal wheels or caterpillars.


Excavator parts

Parts and components of a hydraulic excavator: An excavator is composed of the following parts.


Joining point between arm and pen
