What Are the Different Types of Excavator Booms?

Mar 12 , 2024

Excavators are versatile construction machines designed for various tasks, and their booms play a crucial role in determining their functionality. Booms are the arm-like structures of an excavator that extend from the machine and house the bucket, allowing for digging, lifting, and other operations. Different types of excavator booms cater to specific applications and working conditions. Here are some common types of excavator booms:

  • Standard Boom: The standard boom, also known as the general-purpose boom, is the most common type. It provides a balance between reach and digging depth, making it suitable for a wide range of applications, from digging and grading to lifting and loading.

  • Long Reach Boom: Long reach booms are extended versions of the standard booms, featuring a longer arm and boom combination. These booms are ideal for applications where extended reach is necessary, such as dredging, deep digging, or working in areas with obstacles or hazards.

  • High Reach Boom: High reach booms are designed for vertical reach rather than horizontal reach. These booms are often used in demolition projects, allowing the excavator to reach greater heights for tasks like tearing down tall structures while maintaining stability.

The dipper arm, also known as the stick, is the part of the excavator that connects the boom to the bucket. Variations in dipper arm design include:

  • Straight Arm (Standard): Commonly used for general digging and loading tasks.

  • Sliding Arm: Features a sliding mechanism that allows the dipper arm to extend and retract, providing additional reach without changing the boom length.

  • Articulating (Wrist) Arm: Enables the bucket to rotate independently, allowing for greater flexibility in positioning and digging around obstacles.

  • Zero Tail Swing Boom: Zero tail swing excavators have booms that can rotate within the width of the tracks, minimizing the risk of the machine's rear end swinging into obstacles. This design is advantageous in confined spaces where maneuverability is crucial.

  • Telescopic Boom: Telescopic booms can extend and retract, providing adjustable reach for various tasks. These booms are useful in situations where precise control over the reach is necessary, such as working in tight spaces or performing tasks with varying depths.

  • Swamp or Wetland Booms: Excavators used in swampy or wetland conditions may be equipped with specialized booms designed to provide stability on soft or uneven ground. These booms often have additional features to prevent the machine from sinking.

  • Rock Breaker (Hammer) Boom: Booms designed for rock-breaking applications are reinforced to withstand the impact forces of hydraulic rock breakers or hammers. These booms are commonly used in mining, quarrying, and demolition.

  • Amphibious Excavator Boom: Amphibious excavators are equipped with booms designed for operation on both land and in water. These booms may have additional flotation devices and specialized features for water-based applications like dredging or shoreline maintenance.

When choosing an excavator boom type, it's essential to consider the specific requirements of the job, including reach, depth, stability, and any site-specific challenges. Different excavator models and manufacturers may offer variations in boom designs to cater to diverse construction and excavation needs.
