Key takeaways

  • Micro and mini excavators (under 1t to 3t) are the most hired small plant.
  • Midi excavators (around 5t–10t) suit groundworks and drainage.
  • Dumpers are hired alongside excavators; match sizes so the pair works together.
  • Machine size decides transport: trailer, beavertail or low-loader.

Choosing sizes for your fleet

  • Pair excavators with dumpers of matching capacity.
  • Choose sizes you can transport with your own vehicles and licences.
  • Add a size only when customers keep asking for it.
  • See best first fleet.

FAQs

Common questions

What size mini digger is most popular for hire?
Around 1.5 tonnes is often the most hired, because it suits a wide range of jobs, fits narrow access and travels on a standard plant trailer.
What's the difference between a mini and midi excavator?
Mini excavators are roughly up to 3 tonnes; midi excavators are larger, often around 5 to 10 tonnes, and suit bigger groundworks.
What size dumper goes with a mini digger?
Usually a 1-tonne tracked or high-tip dumper for a 1.5t digger, and larger dumpers for bigger excavators.
