How Much Do You Know About Excavator Boom Configurations?

Mar 09 , 2023

Excavators are a type of heavy construction equipment commonly used in various excavation and digging projects. These machines come in different shapes and sizes, but one of the key features that distinguish them is the boom configuration. Excavator booms refer to the long, horizontal arm that extends from the machine's body to its bucket, allowing it to move and dig with precision.


There are several types of excavator boom configurations, each with its own advantages and disadvantages. In this article, we will explore the most common boom configurations used in the construction industry.


Standard Boom

The standard boom is the most basic and traditional type of excavator boom. It consists of a single long arm that extends straight out from the machine's body to the bucket. The standard boom is suitable for general excavation and digging projects and is often used in small to medium-sized machines. Its simplicity and versatility make it an ideal choice for most construction projects.

Long Reach Boom

As the name suggests, the long-reach boom is an extended version of the standard boom. It has a long arm that allows the excavator to reach deeper and farther than the standard boom. Long-reach booms are commonly used in excavation projects that require digging in deep or hard-to-reach areas. They are also useful for demolition projects where the excavator needs to reach high places.

Armored Boom

Armored booms are designed for use in harsh and abrasive environments, such as mining sites or quarries. They are reinforced with extra steel plating to protect against wear and tear from rocks and debris. Armored booms are heavier and more durable than standard booms, making them more suitable for heavy-duty excavation projects.


Knuckle Boom

Knuckle booms, also known as articulated booms, have two or more joints that allow them to bend and move in various directions. This type of boom is ideal for excavation projects that require precision and flexibility, such as digging trenches or excavating around obstacles. Knuckle booms are commonly used in small to medium-sized machines and can reach higher and farther than standard booms.


Demolition Boom

Demolition booms are designed for use in demolition projects where the excavator needs to break down structures. They are heavier and more robust than standard booms and have a longer reach to access high places. Demolition booms often come with a variety of attachments, such as hydraulic hammers, crushers, and shears, which allow them to break down different types of materials.


Stick Boom

The stick boom is a type of boom that is attached to the back of the excavator's body instead of the front. It is used in projects where the excavator needs to dig straight down, such as when digging deep trenches or digging underground utilities. Stick booms are often shorter than standard booms and have a larger bucket capacity to allow for efficient digging.


Compact Radius Boom

Compact radius booms are designed for use in tight spaces, such as urban construction sites or road work. They have a shorter tail swing radius than standard booms, allowing them to maneuver in confined areas without damaging nearby structures. Compact radius booms are often used in small to medium-sized machines and can be equipped with a variety of attachments for different excavation projects.


In conclusion, excavator boom configurations play a vital role in determining the machine's capabilities and suitability for various construction projects. It's essential to choose the right boom configuration based on the project's requirements and specifications. Consulting with an experienced excavator operator or a construction equipment expert can help you select the appropriate boom configuration for your project.
