The Purpose of Using Long Reach Excavators

Feb 26 , 2022

Excavators are considered to be very important machines, especially for the construction and mining sectors, as they are used to dig or excavate large amounts of ground from the ground. There are many excavator models available in the market. Each excavator has a specific configuration for a particular excavation task. One particular model that is widely used is the long boom excavator. The machine is designed with a long arm, often called a boom. Long boom excavators are most often used to dig deep holes or trenches. 


Many times, long boom excavators are used to excavating rivers or lakes while placed on floating platforms or barges. Some long-reach excavator models are equipped with oversized counterweights designed to counteract the leverage of the moving arm. When equipped with handheld augers and other similar attachments, long-reach excavators are used to reach heights. In addition, when equipped with mechanical thumb attachments, the machine can be used to lift and move pipes, poles, and other similar objects. There are many long-arm excavator brands on the market, but Caterpillar excavators with long-arm designs are considered the best.

Long Reach Arm and Boom

A long-arm excavator is actually a tracked machine designed with a bucket and a digging bucket for digging trenches and holes. Just like a tracked backhoe loader, a long-arm excavator can be found on every major construction or mining site. While it is an ideal machine for digging deep holes and trenches, the long arm excavator has limited digging capacity. The main part is the moving arm, while the bucket bar can extend all the way to the bucket. Special hydraulic cylinders power the three main components: the bucket bag, the boom, and the bucket.

 

Designing a long-arm excavator is a much more difficult task, requiring more than simply attaching the long arm and bucket bar to a standard excavator. Longer and larger cylinders require longer distances and efficient component movement. Longer boom excavators need to be designed with the proper balance of forces to counteract not only the weight of the moving arm but also the added leverage. This additional leverage is created when the bucket is already full. Not including additional balancing may cause tipping when the excavator tries to lift the loaded bucket.

 

How to operate an excavator?

What is the use of the excavator: The excavator is generally used to start materials such as rocks and earth. With its accessories you can also make steel cuts, break concrete, drill holes in the ground, make gravel foundations before paving, shredding rocks, steel, and concrete.

How does an excavator work?

 

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

This piece simulates the movement of the human arm, just as the wrist and elbow would. Then we have the engine which works through a change in hydraulic power.
