Excavators are heavy-duty earthmoving vehicles are made up of buckets, arms, rotating cabs, and movable tracks. Their digging power makes them useful for a variety of tasks, from digging trenches and excavating mines to lifting and transporting waste.
Large excavators have been designed for demanding or specialized tasks. The world’s biggest excavators are used in applications like deep mining excavations and digging under difficult climatic conditions.
In this guide, we rank the world’s largest excavators by their operating weight and detail their origins and features such as their lifting capacity, size dimensions, manufacturers, and more.
Operating weight refers to the overall weight of the machine when it’s in use. This can include the weight of the fuel, operator, engine, bucket capacity, and any attachments to the machine. Operating weight is typically listed in tons, tonnes, or pounds (lb). Here’s how the biggest excavators in the world rank in terms of their weights.
