Large-scale digging and surface mining call for a bucket wheel excavator (BWE). These massive machines are some of the largest ever constructed, and use looping, or wheeled, buckets to continuously dig into the ground. Although smaller applications can be handled with hydraulic excavators, the largest-scale operations demand the hard-driving bucket wheel excavator.
Bucket Wheel Excavator Classifications
Bucket wheel excavators are grouped based on three size categories -- small compact bucket wheel excavators, medium-sized C-frame machines, and the gigantic Twin Tower bucket wheel excavators – separated by length of bucket wheel boom, effective capacity, and service weight. “Small compact” is relative when it comes to wheel excavators: the smallest wheel excavator models weigh 50 tons, but are dwarfed by the 1200-1500 Twin Tower BWEs.
There are few Twin Tower bucket wheel excavator manufacturers in the world, and the largest BWEs are increasingly rare as economics dictate that mining operations opt for the compact bucket wheel excavators. Non-bucket wheel excavators are still manufactured and sold by some the world’s most renowned machinery brands, including John Deere, New Holland, Bobcat and Caterpillar. All wheel excavators are built for prolonged, heavy use, so consider purchasing a used model if possible. A number of specialty web sites can help with your search for a used excavator.
Compact or Mini Wheeled Excavators
Non-bucket wheel excavators are also known as diggers or 360-degree excavators. These versatile, mobile machines are suited to applications such as ditch cleaning, road maintenance, forestry work, materials handling, site-clearing and leveling. The excavators in this segment are typically operated by hydraulics and can attain speeds upwards of 20 mph – compared to 0.37 mph with Twin Tower bucket wheel excavators -- allowing you to move them from one job to another without being loaded onto a truck and trailer for transport. These excavators consist of a house, undercarriage and workgroup.
The operator's compartment, engine compartment, hydraulic pump and distribution components are located in the house, which attaches to the upper side of the undercarriage. The house and workgroup can rotate 360-degrees.
Support for both the house structure and workgroup reside with the undercarriage and its collection of rubber or steel tracks, drive sprockets, rollers, idlers and associated components/structures.
A compact hydraulic excavator’s workgroup is comprised of the boom, dipper or arm, and a bucket or breaker attachment, all connected to the house structure with a swing frame.
Conclusion
When comparing wheel excavators from multiple manufacturers you should consider the spaciousness of and visibility from the cab, how smoothly the levers operate the boom and bucket, operating efficiency and fuel consumption. When ordering a new compact wheel excavator you will find that some manufacturers offer a customization or “Build Your Own” option that allows you to specify the blade, outriggers, and boom attachments based on your needs.
Are you looking for quality wheel excavators? A wheel excavator is a piece of heavy equipment used in excavation, most often in mining. It is a large, powered machine that utilizes a wheel with "buckets" that dig into the earth to remove ground quickly and efficiently. Often the wheel will "dump" the excavated earth onto a conveyer where the dirt may be sifted through for minerals and metals, however in some instances it is used simply to dig in an area. The largest bucket-wheel excavator is in the Guinness Book of World Records for the largest land vehicle ever.
While these machines may be relatively rare and specialized, you do have several options. Some of the things you will want to keep in mind include the size of the machine, and how much earth it can remove in a set amount of time, what sort of land it will be used on and how much power it needs, and any conveyor system. Price is usually quite high, and will vary by the vendor and the factors listed.
Going over your options is always a good idea. Business.com has links to suppliers who may have the excavator you need.
