Excavator and dumper sizes explained for hire fleets
Micro, mini, midi and larger excavators and dumper sizes explained for hire firms: what each does, who hires it and how it's transported.
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.
