FAQs About Used Excavators
Excavators are among the most versatile pieces of earthmoving plant on Australian job sites, handling digging, trenching, lifting, loading and demolition work. Buying used can be a cost-effective way to add a reliable machine to your fleet, particularly for contractors and owner-operators. United Rentals sells used excavators across Sydney, Melbourne, Brisbane, and regional locations, with machines from our maintained hire fleet. Available models range from compact mini excavators for confined-access work through to larger machines suited to bulk earthworks, civil construction and mining projects. Learn more about used excavators in our FAQ section below.
The right excavator size depends on the work you're doing, your site access and how much material you need to move. Mini excavators suit residential, landscaping and confined-space work where access is tight. Mid-size excavators handle general construction, trenching, site preparation, and utility works. Larger excavators are built for bulk earthmoving, civil, road construction, and mining projects. If you're unsure, our sales team can recommend a size based on your project.
A specific excavator licence is no longer required in Australia. Excavators fall under earthmoving plant equipment, which doesn't require a high-risk work licence. However, operators must be able to demonstrate competency, meaning they can use the machine safely and to the manufacturer's instructions. Many sites and employers also require a verification of competency (VOC) before operating on commercial projects. Always check the requirements of your site before you start work.
Excavators are compatible with a wide range of attachments depending on the machine size and the work. Common attachments include general purpose buckets, mud and trenching buckets, rock breakers for demolition and hard ground, augers for drilling holes and installing posts, compaction wheels and plates for trench and surface compaction, and tilt buckets for precision grading. Attachment compatibility depends on the excavator's hydraulic capacity and hitch type, so check before purchase if you're planning to use specific attachments.
