the-worlds-biggest-mining-excavators

Excavators are versatile, heavy machines deployed to move large objects, such as soil and other earth materials. Used extensively in mining, road and building construction and demolition, they are an essential part of a fleet on any major project.

In addition to varying greatly in size, there are also a number of different types of excavators, including crawlers, draglines, suction, skid steer and long reach. Each have their own strength that can be applied to different circumstances and specialised for certain jobs, which is only helped by an array of useful attachments. Here we take a look at the world’s top ten largest excavators, based on their operating weight:
