+ Delivery Rate & Operator Rate
We honor the lowest rate on all long term rentals.

Known by those at the Komatsu company as the Komatsu PC 78UU-8 Compact Hydraulic Excavator, this midi excavator rental is an excellent choice for jobs that require a bigger machine without going all the way to a full heavy excavator. That's what midi excavators like this one are for - versatility.

The PC78 UU is ideal for smaller spaces

A highly maneuverable boom and a very large work envelope allows for minimal track movement and ensures efficiency at low operating costs. The size of this excavator rental is ideal for jobs that require careful movement so as not to disturb surroundings, such as a busy residential or urban environment. 

The Komatsu PC78 UU rental is tailored for an urban environment

"Zero Swing" of the Komatsu technology allows the boom to be flexible, letting it get to hard-to-reach corners and work around senstive spots with pipes, foundation and wiring with ease and efficiency.
