Choosing the Right Excavator: Essential Factors and Types

, | June 4, 2025 | By

Many industries, such as construction, landscaping and agriculture, rely on excavators for heavy-duty applications, including digging and hauling materials. Excavators are an excellent way to increase productivity and efficiency at your job site while reducing operating costs.

Selecting the right excavator involves considering power, size and application needs to ensure it meets the demands of your projects. In this guide, you’ll learn about the different types of excavators—including mini, standard and wheeled—and their weight classes and sizes to help you choose the best option for your application.

Key Factors to Consider

  • Digging Depth: Whether digging trenches for utility work or excavating for large-scale mining applications, selecting an excavator with an appropriate digging depth is crucial. Opting for a machine with greater digging capabilities ensures you can easily complete your tasks.
  • Reach: The reach of an excavator is determined by its boom length. While a shorter boom enhances maneuverability and productivity, certain tasks demand a longer boom for optimal performance. Ensuring your machine has the right reach allows you to tackle specialized jobs without limitations.
  • Capacity: Excavators often serve as material handling equipment, making it vital to assess the weight you typically need to move. Understanding your load capacity requirements helps you select a machine with sufficient power and lifting capability to efficiently handle your site’s demands.
  • Hydraulics: The hydraulic system in an excavator significantly impacts its overall control and functionality. Advanced hydraulic controls enhance operator comfort and determine the types of attachments your machine can accommodate, expanding its versatility.
  • Features: Modern excavators have innovative features that enhance efficiency and safety on job sites. Features such as grade control, grade assist, E-fencing and integrated scales improve operator control, reduce rework, boost safety and lower operational costs. 

Excavator Size and Weight Classes

Excavators come in various sizes to suit every project, from residential landscaping to large-scale commercial construction. Understanding the benefits and challenges of different sizes of excavators can help you make an informed decision about the right size excavator for the job.

Mini Excavators

Micro or mini excavators are best suited for tight job sites where standard-sized excavators can’t fit or maneuver properly. They are ideal for small landscaping jobs, infrastructure trenching and digging holes. Additionally, mini excavators have zero or near-zero tail swings, making them perfect for jobs requiring precision, such as installing underground pipes or gas lines. Their lightweight nature makes them easier to transport and more fuel-efficient, reducing operational costs. However, they lack the power and capacity for larger-scale projects.

Standard Excavators

Standard-sized excavators are the most common size for commercial construction projects and offer enough power and hauling capacity to handle tough jobs. Many standard hydraulic excavators support a variety of work tools, allowing contractors to customize their excavators to meet specific project needs. However, their larger size and weight can cause soil damage on softer ground and present transportation and storage challenges.

Standard excavators are sometimes further divided into small and medium excavators. Small excavators balance power and maneuverability, while medium excavators provide increased reach and digging depth for more demanding tasks.

Large Excavators

Large excavators are best suited for heavy-duty applications, such as commercial construction, demolition and large-scale earthmoving projects. These machines can efficiently dig foundations for large structures like shopping malls or apartment complexes. However, their size requires significant storage space and specialized transport solutions, making them more suitable for major projects where their high capacity outweighs logistical challenges.

Excavator Types

You have many flexible options for excavation models and equipment types to meet the needs of your applications. Different types of excavators are better suited to heavy-duty jobs, while others are ideal for less intensive tasks. Some of the most common excavation equipment types and their uses are listed below.

Standard Excavators

Standard tracked excavators use a boom, stick and bucket arm attachment at the front of the equipment. They are designed for heavy-duty applications in industries such as construction, mining and landscaping. Their rotating tracks provide traction and stability, allowing them to navigate steep slopes and rugged terrain.

Wheeled Excavators

Unlike standard excavators that run on tracks, wheeled excavators use wheels for mobility. These machines are well-suited for urban construction, roadwork and flat terrain applications. Their ability to move between job sites without a trailer can save time and transportation costs.

Long-Reach Excavators

Long-reach excavators feature an extended arm and boom, making them ideal for jobs requiring access to hard-to-reach areas. These excavators are often used in demolition projects and excavation tasks that require a longer reach.

Dragline Excavators

Dragline excavators are heavy-duty machines primarily used for large-scale applications like harbor construction, canal dredging, and strip mining. They use a bucket system suspended by chains and wire rope to excavate and transport materials.

Backhoes

Backhoes differ from standard excavators by having the boom attached to the back of the equipment. They are versatile machines that can handle digging, soil leveling and material transportation simultaneously, making them an excellent choice for multi-functional applications.

Hydraulic Shovels

Hydraulic shovels are designed for intense mining and excavation tasks. These powerful machines feature large buckets for moving heavy materials such as minerals, rocks and soil.

Expand Capabilities with Attachments

Excavators can do much more than just digging. Selecting the right attachments allows you to adapt your machine for various tasks, making it a versatile investment. Some commonly used attachments include:

  • Buckets: Essential for digging and material handling.

  • Hammers and Breakers: Used for demolition and breaking through tough materials.

  • Couplers: Enable quick attachment changes, increasing efficiency.

  • Rippers: Assist in breaking up compacted ground.

  • Grapples and Thumbs: Useful for handling logs, debris, and irregular materials.

  • Augers: Ideal for drilling holes in soil, clay, and rock.
