A bucket chain excavator (BCE) is a piece of heavy equipment used in surface mining and dredging. BCEs use buckets on a revolving chain to remove large quantities of material. They are similar to bucket-wheel excavators and trenchers. Bucket chain excavators remove material from below their plane of movement, which is useful if the pit floor is ...
Bucket-wheel excavators have been used in mining for the past century, with some of the first being manufactured in the 1920s. [1] They are used in conjunction with many other pieces of mining machinery (conveyor belts, spreaders, crushing stations, heap-leach systems, etc.) to move and mine massive amounts of overburden (waste). While the ...
The length improves axial weight distribution and bucket capacity can be enhanced. The two-part construction with central articulation helps in tracking and maneuverability. In mining, there is a limitation for shifting heavy equipment, and sometimes, an LHD has to be shifted through a shaft while dismantled. [1]
The P&H L-2350 Wheel Loader (formerly the L-2350 loader) is a loader used for surface mining.It is manufactured by Komatsu Limited.It holds the Guinness World Record for Biggest Earth Mover.
Bagger 288 (Excavator 288), previously known as the MAN TAKRAF RB288 [2] built by the German company Krupp for the energy and mining firm Rheinbraun, is a bucket-wheel excavator or mobile strip mining machine. When its construction was completed in 1978, Bagger 288 superseded Big Muskie as the heaviest land vehicle in the world, at 13,500 tons. [3]
A heavy equipment operator drives and operates heavy equipment used in engineering and construction projects. [7] [8] Typically only skilled workers may operate heavy equipment, and there is specialized training for learning to use heavy equipment. Much publication about heavy equipment operators focuses on improving safety for such workers.

The much larger type which is erected on site is commonly used in strip-mining operations to remove overburden above coal and more recently for oil sands mining. The largest heavy draglines are among the largest mobile land machines ever built, weighing up to 13,500 tons, while the smallest and most common of the site-erected type weigh around ...
