Taking A Look At The Main Parts Of An Excavator

Excavators are of great importance in construction sites. Excavators are made up of many parts that work together to get the job done.

Main Parts of an Excavator

As mentioned, an excavator has many parts that work together to get the job done. The most common parts are:

Motor : it creates the power used in moving an excavator. The motor can be powered by petrol, fuel or even electricity. It's good to note that while there are electric excavators in the market, they are very rare and they are designed to work in specialized areas.

The hydraulic motor is one of the most important motors in an excavator. This is the motor that rises and extends the excavator arm.

Excavator Arm : The arm is attached to the lower part of the frame chassis and has two main sections that are joined with a hinge. The sections have pistons that move them. When the first piston extends, the rod pushes against the arm and raises it then extending the section. The second arm then contracts and expands thus raising and lowering the second section. To help the excavator to scoop and dig, the arm has a bucket loader.


They are rigid and fixed in one place. The tracks are stationed around a series of gears that turn after receiving power from the drive shaft that is connected to the engine. When the tracks are in gear they roll the excavator back and forward in a straight line.

For you to turn the excavator you have to stop one track and put the other in motion. To spin the excavator you have to put one track into reverse and the other into forward.

Taking Care of Excavator Parts

Since the excavator parts are involved in tough work, you need to take good care of them for them to last for a long time. One of the things that you should do is to regularly oil all the moving parts. Oailing not only promises rust, it also ensures that the parts move without strain.

In addition to oiling, you also need to regularly clean the excavator parts. For example, if you are working on a construction site you should clean the excavator at the end of the day. This prevails dust from accumulating that damaging the expensive parts.


This is what you need to know about excavator parts. In addition to taking good care of the parts you also need to ensure that you buy them from a reputable seller.
