mini excavator

Heavy equipment is fundamental in completing construction or industrial projects. Luckily, some machines offer versatility so that general contractors, project developers, and property owners can finish multiple tasks using one piece of equipment. Among the versatile machines builders utilize is a mini excavator. If you’re a general contractor, project developer, or property owner, you probably need to look into this valuable piece of machine.

What Is a Mini Excavator?

Before going through all the crucial things about mini excavators, you must first understand the basics by asking yourself, “What is an excavator?”.

Simply put, an excavator is a piece of heavy equipment that’s commonly used to operate earthmoving tasks like digging and lifting massive amounts of soil and gravel. An excavator can function differently depending on the attachment connected to the equipment (more to that later). In that case, a mini excavator, sometimes called a compact or small excavator, is the smallest version of the standard excavation machine that’s ideal for worksites with smaller and tighter workspaces.

Mini excavators weigh below 6 tons or about 13,227 lbs, much less than the conventional excavator. Because a compact excavator is smaller and lighter, it can lessen track marks and ground wreckage. They’re more convenient to use than the larger ones for construction projects with limited spaces like narrow road repairs. This also makes them suitable for indoor work as some of the mini excavators can actually fit doorways.

What Is the Purpose of a Mini Excavator?

Although standard and compact excavation machines serve the same function, they still have differences beyond their sizes. A mini excavator uses several bucket attachments to perform various projects. With its size, a mini excavator can efficiently function in smaller construction and landscaping projects with tough-to-reach spots.

Here are some construction jobs where you can use compact excavators:

  • hole digging
  • grave digging
  • sewer line repairs
  • pool and other water line installation
  • tree installation or removal
  • small structure demolitions
  • snow plowing
  • roadside works
  • home renovations

Primary Mini Excavator Parts

Having established the nature and function of a small excavator, here are the three fundamental components you need to know: the undercarriage, cab, and the arm and boom.


The undercarriage is the supporting framework of the mini excavator. Tracks or wheels are fitted in the undercarriage to help the excavator move. Mini excavators typically use wheels when working on challenging and stable surfaces like roads, cement, or inside buildings.

Here are the other parts that are connected to the undercarriage:

Excavator Tracks, Frames, Pad, Chains, Shoes, and Bolts

Tracks, usually made with steel-inforced rubber, are used when traveling over rough ground to ensure a steady ride. The track frame connects the excavator tracks to the undercarriage. It functions the same as an axel. Having track pads installed can also reduce operating noise, vibration, and wear and tear while also improving traction.

In addition, track chains, shoes, and bolts help move the mini excavator efficiently. The chains are composed of adjustable links that perform similarly to bicycle chains. On the other hand, track shoes are used to pull the excavator along while being linked to the bolts to form the whole excavator track.

Rock Guards, Sprockets, Rollers, and Idlers

To prevent damage to your excavator from rocks and other debris, you can install rock guards on the tracks. Moreover, sprockets move between the track chains to drive the compact excavator.

Rollers and idlers are the final parts that help the tracks run easily. Rollers align and move chains between an excavator’s sprocket and idler. The bottom and top rollers help the chains to function. Large metal wheels known as idlers are used to guide the excavator’s tracks.


The cab is where the operator sits. With swing gear attached to the undercarriage, it helps the mini excavator turn 360 degrees for maximum visibility. Depending on the model, here are the following parts attached to the cab:

Main Controls

This part is the mission control of the excavator. Here, you’ll find the fundamentals like basic controls, wheel mechanisms, and safety features.

Rollover Protective Structure and Counterweight

Also called ROPS, this part is an essential safety feature. It protects the operator from any possible rollovers. The counterweight, on the other hand, acts as a counterforce to the excavator when digging. It increases the operator’s leverage and prevents the machine from toppling over.


The engine provides the machine with the power necessary to operate the boom and the tracks. Engines are typically housed near the cab to provide easier access to maintenance and are mostly powered by diesel fuel.

Hydraulic Fluid and Fuel Tanks

The tanks are typically located within the operator station, and most models operate with hydraulic systems. Fuel tanks, on the other hand, store the energy needed to power the machine.

Main Control Valve

Hydraulic mini excavators have one central control valve that regulates oil pressure and powers hydraulic components like the arm and boom.

Boom and Arm

Excavators perform digging using the boom and arm parts. The arm and boom cooperate to accomplish several earthmoving tasks. The boom is at the front part attached to the cab that holds the arm. Additionally, the arm connects to the bucket. Both of these parts work together to wield the bucket in every place.

With that, here are the other parts that can be attached to the boom and arm to maximize the machine’s capability.


Buckets are the most common type of excavation attachment, and the mini excavator bucket sizes can range from 12-24 inches. Different bucket attachments can also replace the standard bucket of mini excavators to perform other construction activities.

Check out these mini excavator bucket attachments to fully utilize small excavation machines.

Trenching Buckets – Compact excavators typically use trenching buckets for construction productivity to facilitate precise, deep digging. This bucket creates trenches by easily breaking the ground using abrasion-resistant material.

Heavy-Duty Buckets – Also called teeth buckets, this bucket is typically used when digging in challenging environments, such as soils with a high concentration of rocks. The teeth on the end make it easy to puncture rough areas, and the high-strength steel makes the bucket last longer when it’s used to move abrasive materials.

Grading Buckets – A grading bucket has a broader and smoother design compared to other buckets. This bucket is typically used for grading, sloping, leveling, backfilling, and transporting lighter materials like dirt or mulch.

Angle Tilt Buckets – Tilting at 45 degrees, angle tilt buckets can help operators work on slopes. This bucket is used to level and grade uneven ground. The operator can move the bucket to match the slope it needs to work.


The attachments are different kinds of parts inserted in the compact excavator to make the machine more useful for other construction or industrial projects.

Here are the mini excavator attachments you can use for your small excavators to maximize their versatility:

Hydraulic Thumbs – Hydraulic thumbs are highly recommended for grabbing and placing materials like larger stones, branches, and logs. This attachment is easy to use because it can be operated using the excavator’s thumbwheel.

Hydraulic Breakers – Hydraulic breakers, also known as hydraulic hammers, are mainly used for demolition works. The hydraulic energy that fuels this attachment makes it easier for workers to break down rocks, concrete, and asphalt during excavation or demolition.

Auger Attachments – Auger attachments are used to make hole digging easier. They help dig trenches for various purposes, including installing fence posts, planting trees, constructing concrete barriers, and laying the groundwork for pylon stability.

Plate Compactors – A plate compactor can shorten the time it takes to compact trenches and rough terrain. This attachment also eliminates the physical demands that would otherwise be placed on the worker in squeezing soil sod.

Tiltrotators – A tiltrotator can be utilized as an attachment between the machine arm and the actual attachment for greater freedom of movement. The tail can swing in any direction, and the attachment can be rotated 360 degrees and tilted up to 45 degrees with complete freedom.

Quick Couplers – Quick coupler attachments limit the time it takes to change attachments on the mini excavator. For this attachment to work, the operator just needs to push designated buttons in the cab. This makes it easy to switch attachments while the operator is at work.
