What this guide helps you decide
Estimate whether your project needs one excavator or multiple machines based on work fronts, loading demand, trenching output and programme pressure. The best option depends on site access, ground conditions, material type, working distance, loading method, hire duration and production target.
Project Plant Hire can assist with machine availability, wet hire options, lowbed transport, attachments and practical fleet recommendations based on the work you need completed.
Key selection factors
Digging depth and reach
Trenching, foundations and bulk excavation all need different boom reach, bucket size and machine weight.
Material hardness
Soft soil, rock, demolition rubble and blasted material affect bucket choice and production rate.
Loading requirement
The excavator must match ADTs, tippers or stockpile work so loading cycles remain efficient.
Quick recommendation table
| Situation | Best starting option | Typical use |
|---|---|---|
| 5 ton mini excavator | Tight access | Small trenches, estates, landscaping and confined work |
| 20–35 ton excavator | General civil work | Trenching, loading, foundations and roadworks |
| 40–120 ton excavator | High production | Bulk earthworks, quarry support and mining |
Common mistakes to avoid
- Choosing equipment only by hourly rate instead of output and total project cost.
- Ignoring haul distance, access restrictions, tipping space or loading conditions.
- Using one machine type when a balanced fleet would complete the work faster.
- Booking equipment before confirming ground conditions, attachments and mobilisation requirements.

Frequently asked questions
Can Project Plant Hire recommend the correct machine?
Yes. Send the site location, project type, material, access conditions and expected hire duration and we can recommend suitable options.
Do you offer wet hire?
Wet hire can be discussed depending on machine availability, location and project requirements.
Can machines be supplied with support equipment?
Yes. Many projects require combinations such as excavators with ADTs, rollers with water bowsers, crushers with screens or lowbeds for mobilisation.
