Industry knowledge:

What is a mini excavator?

A compact or mini excavator is a tracked or wheeled vehicle with an approximate operating weight from 0.7 to 8.5 tonnes. It generally includes a standard backfill blade and features independent boom swing.

Hydraulic Excavators are somewhat different from other construction equipment in that all movement and functions of the machine are accomplished through the transfer of hydraulic fluid. The compact excavator's work group and blade are activated by hydraulic fluid acting upon hydraulic cylinders. The excavator's slew (rotation) and travel functions are also activated by hydraulic fluid powering hydraulic motors.

Most compact hydraulic excavators have three distinct assemblies: house, undercarriage and workgroup.

In recent years, hydraulic excavator capabilities have expanded far beyond excavation tasks. With the advent of hydraulic powered attachments such as a tiltrotatorbreaker, a grapple or an auger, the excavator is frequently used in many applications other than excavation and with the tiltrotator attachment, actually serves as an effective tool carrier. Many excavators feature quick coupler (quick-attach) mounting systems for simplified attachment mounting, dramatically increasing the machine's utilization on the jobsite.

Why get a mini excavator?

A mini excavator is small and lightweight enough to transport quickly to the site of construction. However, it is not too small as to be underpowered. In fact, advances in hydraulic systems make some mini excavators outperform larger construction machines. Some examples of mini excavators are the Bobcat E32i Compact Excavator, Yanmar ViO17 Mini Excavator and John Deere 50G Compact Excavator.

There are other advantages to the small size and low weight of a mini excavator. These two qualities mean that such an excavator is compact enough to maneuver in confined areas and light enough to do only minimal damage to the landscape. For example, a Zero Tail Swing (ZTS) mini excavator has a house that does not overhang its tracks and therefore allows 360-degree rotations without the cab bumping against obstructions.
