Best Mini Excavator: CAT Mini Excavator

CAT mini excavator is a type of CAT excavator and is popular all over the world.

What is CAT mini excavator?

A wide range of mini excavators covers excavators up to 10 tons. There is no standardization, so what one manufacturer calls a mini may be called a compact, small or medium excavator by another. Each manufacturer makes a mini excavator size chart.

Caterpillar is one of the best-known names in construction equipment, and its excavator products are the number one in the industry.

Caterpillar offers a wide range of mini excavators, ranging from 14.3kw 1768kg of CAT 301.5 mini excavator to 51.8kw 10172kg CAT 310 mini excavator. They are sized to meet a variety of needs.

What is the best size mini excavator?

There is no standard classification that defines the size of mini excavators, that is, there is no best size of mini excavator. If you are doing a mini excavator comparison then here are the simple classifications.

1 to 2 tons

The smallest mini excavators are ideal for tight spaces and small jobs like digging trenches, planting small trees or doing light demolition, even indoors. These mini excavators are simple to use and can be transported by pickup or trailer. Since they are lightweight, they won’t damage the jobsite and are suitable for most spaces.

3 to 5 tons

This is the most versatile machine and the best sized mini excavator for small jobs but with the power, technology and comfort of its larger counterparts.

5 to 10 tons

These small excavators are capable of large jobs such as installing swimming pools and digging utility ditches. The smaller excavators in this class can dig about 10 feet deep, while the larger ones can dig more than 15 feet.

How much does a CAT mini excavator cost?

The price of a CAT mini excavator depends on the size of the machine and its capabilities.

The smallest model, a Carter mini excavator, will cost around $33,000 to $37,000.

A mid-size model is around $48,000.

Larger models of CAT mini excavators cost about $112,000.

How to use CAT mini excavator?

The driver needs to have relevant operating knowledge in the process of operation. Only with relevant operating common sense can the damage of the small excavator be reduced, so as to achieve reasonable construction.

The right operation handle (right-hand operation) controls the work of the arm and the bucket

The handle pulls the arm backward to raise the arm, and the handle pushes the arm forward to descend. When the track contacts the ground, hold the handle and push the excavator forward. Move left to close the bucket, and move the operating handle to the right to move the bucket.

The left operating handle (left-hand operation) controls the arm and rotation.

The handle pulls the arm back, pushes the arm forward and turns it outward. The right side of the operating handle is the right excavator, and the left side is the left side. Adjust the direction. That is, adjusting the left operating handle after adjusting the forearm and rotating action is the opposite.

Walking pedal operation

Push the excavator forward and pull the excavator backward. For quick steering, one can push forward and one can withdraw.

Proper operation of the small excavator can not only improve work efficiency, prolong the life of the machine, but also ensure safe operation (put the machine on a relatively flat ground); avoid damage to machinery and workers caused by improper operation.


How to choose a suitable CAT mini excavator?

There are many factors to consider when choosing a CAT mini excavator, and the excavator you choose should be able to meet your excavation, lifting or demolition needs. It must fit in the work area and should be easy to travel to and from the job site. Here are a few factors to consider:

Working weight

The working weight is used to calculate the lifting capacity of the mini excavator, which takes into account the height and radius of the lift. It also determines the pressure the mini excavator will exert and the impact it will have on the ground.

Digging depth

Digging depth indicates how deep the excavator can dig into the earth and remove it.

Discharge height

Dump height is the maximum height an excavator can lift and dump a load.

Bucket Digging Force

Bucket digging force is the maximum force applied through the bucket. The higher the digging force, the greater the ability of the CAT mini excavator to dig and lift.


The size of the mini excavator, including the height, width and length of the machine – will affect how it fits in the work area and how you transport it to and from the jobsite. Large mini excavators usually have to be transported by a driver with a commercial license, while small mini excavators can be loaded on pickups.



Mini excavators can also be used in various projects. If you are looking for a mini excavator, then CAT mini excavator is your best choice.
