An excavator is one of the most useful machines when it comes to construction. The device helps in performing tasks that you cannot do with human effort. Although excavators have increased on the speed of work, experts are still modifying the machines in order to reduce on their weight as well as minimize on the noise generated at the jobsite.

General description of an excavator

An excavator consists of different parts that make it efficient in performance various tasks on the construction site. To begin with, it features an undercarriage that comes with wheels for the enhancing on the mobility of this machine. Through research, experts are trying to improve on the ride of the wheel. The older models features an excavator counterweight suspended at the rear end of the machine for providing additional capability during the process of lifting and force needed for digging deep into hard surfaces. The modern models feature an excavator counterweight that remains inside the machines track with when it swings from one point to another. This makes its movement safer while at the same time improving on the maneuverability of the device when functioning in restricted areas. Some of the common excavators on the market feature diesel engines for generating hydraulic pressure used in supporting numerous operations. Furthermore, some of the modern excavators have electric motors that use fuel cells for the generation of power. Fuel cells are becoming more popular in many machines because they are not only efficient but also environmentally friendly. Moreover, the fuel cells are also smaller and lighter when compared to the diesel engines in the old excavators. The operator cabin has also undergone some modifications to make it more spacious and comfortable than before.
Components of an excavator and their uses
The basic mechanism of any excavator comprises of an undercarriage that features tracks, frame, final drive and blade. The final drive features a hydraulic motor as well as gears that help in driving the tracks of the excavators. The operator cabin, excavator counterweight, engine, fuel tanks and hydraulic system on the undercarriage serve different functions. Their location enables the excavator to turn through an angle of 360 degrees without any form of hindrance. The main purpose of the engine is to help in driving the hydraulic pumps of the excavator so that they provide oil at high pressure for slewing the motor and other accessories of the excavator. The boom makes motions up and down as well as shifts from the right to the left hand side of the excavator. The boom features an arm that helps in imparting strong force on the ground as the machine digs deeper. There is also a bucket at the end of the arm for carrying soil and any other debris. The excavator also features other attachments that help in crushing, boring, ripping and lifting different loads at the construction site. While using the excavator, you need to be very careful since counterweight accidents are very common especially when removing it from the machine. Most of the drivers will remove the excavator during the process of transportation to minimize the chances of hitting some of the workers.

Improvements on the excavator to enhance on its safety

• Excavator counterweight removal system
A hydraulic removal system can make it safe to detach counterweight from the excavator. While using the system, ensure that you follow the instructions provided to avoid any form of injury that may arise along the way.

• Rear view camera
The rear view camera will eliminate the need for the operator to turn round in order to see whether it is safe to remove the counterweight or not. This system is very good for the tail swinging design of excavators.

Applications of an excavator

With an excavator, the work speed has increased greatly. The machines are very useful in different areas including the following

• Removing of wood from the forest

• Normal landscaping and grading

• Cutting of bushes with the help of its attachments

• Structure demolition and removal of any resultant debris

• Laying down heavy pipes

• Dredging of rivers

• Installing piles within foundations

• Digging trenches, holes as well as foundations

• Handling of heavy weight materials at the construction site

In summary, an excavator is very crucial during the process of construction. The machine has undergone modification to increase on its efficiency while at the same time making safer. Some of the expected modifications include weight and noise reduction. As an excavator operator, you need to be very careful while using the machine so that you do not injure some of the workers on the site.
