45 Ton Excavator45 Ton Excavator Overview
The 45 ton excavator class is selected when the project needs mining support, quarry loading and mass excavation. It is important to choose this size for the work being done because excavator productivity is driven by bucket capacity, digging depth, reach, cycle time, access and the haulage fleet available on site.
For this class, the main advantage is that it can deliver the required production more efficiently than a smaller excavator while avoiding unnecessary cost where a larger mining-class unit is not justified. It is most effective when matched with the right buckets, operator, haul trucks and site layout.
Project Plant Hire can help assess whether a 45 ton excavator is the correct choice based on material type, required depth, production target, available working area, haul distance and mobilisation requirements.

Available Attachments and What They Are For
General purpose bucket
For normal digging, loading and general earthmoving where material is not excessively abrasive or oversized.
Rock bucket
For harder, abrasive or rocky material where a stronger bucket structure and teeth are required.
Trenching bucket
For service trenches, drainage lines and narrower excavation work where width control matters.
Hydraulic breaker
For breaking rock, concrete or hard material when ripping or normal excavation is not sufficient.
Ripper
For loosening hard ground, shale or compacted layers before bucket excavation.
Quick hitch
For faster attachment changes where the machine is doing multiple types of work on the same site.
Why Choose This Excavator Size?
Reason 1
Better suited to demanding material than smaller excavators
Reason 2
Pairs well with 40–45 ton ADTs
Reason 3
Improves loading cycle times on larger sites
Reason 4
Can carry larger buckets and heavier attachments
When Not to Use a 45 Ton Excavator
Choosing the correct machine size is as important as choosing a capable supplier. A 45 ton excavator may not be the most economical choice when:
- The scope is light or medium civil construction
- The site has tight access or weak haul roads
- A smaller excavator can meet production at lower mobilisation cost
- The project requires 70 ton-plus mining production
Recommended Fleet Pairing
The right support fleet depends on production targets, haul distance, material density and site access. These machines are commonly considered with 45 ton excavator hire:
45 Ton ADT
Commonly paired with 45 Ton Excavator hire depending on haul distance, site access, material and production target.
D8 Dozer
Commonly paired with 45 Ton Excavator hire depending on haul distance, site access, material and production target.
D9 Dozer
Commonly paired with 45 Ton Excavator hire depending on haul distance, site access, material and production target.
Front End Loader
Commonly paired with 45 Ton Excavator hire depending on haul distance, site access, material and production target.
Water Bowser
Commonly paired with 45 Ton Excavator hire depending on haul distance, site access, material and production target.
Lowbed Transport
Commonly paired with 45 Ton Excavator hire depending on haul distance, site access, material and production target.
Project Plant Hire Recommendation
Practical machine selection advice
Choose the 45 ton excavator when its bucket size, reach, digging depth and loading capability match the required daily output. If the excavator is too small, haul trucks wait and production suffers. If it is too large, mobilisation, fuel and operating cost may exceed the benefit. Send us your volumes, haul distance and material type and we can help narrow the correct class.

Frequently Asked Questions
What bucket size does a 45 ton excavator typically use?
Typical bucket capacity for a 45 ton excavator is around 1.8 m³ to 2.8 m³. The exact bucket depends on material density, breakout force, machine model and whether a GP, rock, mud or trenching bucket is fitted.
Why would I choose a 45 ton excavator instead of a smaller excavator?
Choose the 45 ton excavator when the smaller machine cannot meet the required production, reach, digging depth, loading height or attachment requirements economically.
When is a 45 ton excavator too large for the job?
It may be too large when access is limited, quantities are small, ground conditions cannot carry the machine or mobilisation cost is not justified by the production benefit.
Can a 45 ton excavator use a hydraulic breaker?
Hydraulic breaker options may be available where the carrier machine and attachment are compatible. Breaker size must be matched to the excavator class and material.
Which trucks should be paired with a 45 ton excavator?
The ideal haulage depends on material, cycle distance and loading target. Common support may include tippers, ADTs or larger haul trucks depending on the excavator class.
Can I request CAT, Komatsu, Volvo or another brand?
You can request a preferred brand, but Project Plant Hire works brand-neutrally and supplies suitable leading-brand or equivalent machines subject to availability.
Do you supply an operator with the 45 ton excavator?
Operator and wet hire arrangements can be discussed as part of the quotation, depending on location, duration and site requirements.
