What is the most common type of excavator?
The crawler excavator is the most widely used type, thanks to its versatility, stability on uneven terrain, and suitability for general construction, mining, and trenching projects.
What size excavator do I need for my project?
This depends on the task, site conditions, and space. Mini excavators are ideal for landscaping or residential jobs, while medium to large machines suit commercial and industrial work.
What attachments can I use with an excavator?
Excavators can be fitted with buckets, hydraulic breakers, grapples, augers, and tiltrotators to expand their capabilities—from digging to demolition and lifting.
Should I rent or buy an excavator in Canada?
Renting is ideal for short-term or one-off jobs, while buying makes sense for ongoing projects. Consider cost, storage, and usage frequency when making your decision.
What is a mini excavator used for?
Mini excavators are best for tight spaces, small jobs, and light digging work—common for landscaping, utility installation, or indoor demolition.
How deep can an excavator dig?
Excavator digging depth varies by size. A standard 20-tonne machine can typically dig around 6–7 metres deep, while long-reach models can go beyond 10 metres.
