MAN Takraf RB293
Bagger 293, previously known as the MAN TAKRAF RB293, is a giant bucket-wheel excavator made by the German industrial company TAKRAF, formerly an East German Kombinat. It owns or shares some records for terrestrial vehicle size in the '' Guinness Book of Records''. Bagger 293 was built in 1995, one of a group of similar sized 'sibling' vehicles such as the Bagger 281 (built in 1958), Bagger 285 (1975), Bagger 287 (1976), Bagger 288 (1978), Bagger 291 (1993). It is used in a brown coal mine near Hambach in Germany. It is called Bagger 293 by its current owner, RWE Power AG (the second-largest energy producer of Germany). It was called RB293 by its former owner, the brown coal company Rheinbraun, which in 1932 became a daughter company of RWE. During an internal reshuffle in 2003 it merged with another daughter company to form RWE Power AG. Manufacturer TAKRAF generally refers to it as an excavator of the type SRs 8000.

Tagebau Hambach
The Tagebau Hambach is a large open-pit coal mine (german: Tagebau) in Niederzier and Elsdorf, North Rhine–Westphalia, Germany. It is operated by RWE and used for mining lignite. The mine is on the site of the ancient Hambach Forest, which was purchased by RWE in 1978. The company then cut most of the forest down and cleared it to mine. Only 10% of the forest area remains. RWE planned to clear half of the remaining area between 2018 and 2020. This plan was met with massive protests in the autumn of 2018 and was temporarily stopped in October 2018 by the supreme administrative court of North Rhine–Westphalia (Oberverwaltungsgericht für das Land Nordrhein-Westfalen). Begun in 1978, the mine's operation area currently (as of end of 2017) has a size of 43.8 km2, with the total area designated for mining having a size of 85 km2. It is the deepest open pit mine with respect to sea level: the bottom of the pit, with up to from the surface, is below sea level, t ...

TAKRAF
TAKRAF Group (“TAKRAF”), is a global German industrial company. Through its brands, TAKRAF and DELKOR, the Group provides equipment, systems and services to the mining and associated industries. Foundation and History While the official foundation date of TAKRAF Group is given as 1948, its origins stretch back to 1725 when the Lauchhammer works for fabricating construction equipment were established, in then Prussia, together with the first blast furnace for producing iron. 1809 saw the start of activities as a mechanical engineering company, as well as major milestones being contributed to Germany’s industrial history. These included, in 1874, the Lauchhammer works commencing high-rise - and iron bridge construction in Oberhammer, and the start of fabrication of overburden and lignite mining equipment. The Lauchhammer works continued to contribute important firsts into the 20th century. The first overburden conveyor bridge was supplied in 1924, followed, two years later ...

Bucket-wheel Excavator
A bucket-wheel excavator (BWE) is a large heavy equipment machine used in surface mining. The primary function of BWEs is to act as a continuous digging machine in large-scale open-pit mining operations, removing thousands of tons of overburden a day. What sets BWEs apart from other large-scale mining equipment, such as bucket chain excavators, is their use of a large wheel consisting of a continuous pattern of buckets used to scoop material as the wheel turns. They rank among the largest vehicles (land or sea) ever produced, and the largest of the bucket-wheel excavators (the 14,200 ton Bagger 293 still holds the Guinness World Record for the heaviest land-based vehicle ever constructed). History Bucket-wheel excavators have been used in mining for the past century, with some of the first being manufacture ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Guinness Book Of Records
''Guinness World Records'', known from its inception in 1955 until 1999 as ''The Guinness Book of Records'' and in previous United States editions as ''The Guinness Book of World Records'', is a reference book published annually, listing world records both of human achievements and the extremes of the natural world. The brainchild of Sir Hugh Beaver, the book was co-founded by twin brothers Norris and Ross McWhirter in Fleet Street, London, in August 1955.

Bagger 288
Bagger 288 (Excavator 288), 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. It took five years to design and manufacture and five years to assemble, with total cost reaching $100 million. In 1995, it was itself superseded by the slightly heavier Bagger 293 (14,200 tons). NASA's Crawler-Transporter remains the largest self-propelled land vehicle in the world, since bucket-wheel excavators are powered by an external power source, and the Overburden Conveyor Bridge F60s hold the title of largest land vehicle of any type by physical dimensions. Objective The Bagger 288 was built for the job of removing overburden before coal mining at the Hambach surface mine in Germany. It can excavate 240,000 tons of coal or 240,000 cubic metres of overburden daily &n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown Coal
Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat. It has a carbon content around 25–35%, and is considered the lowest rank of coal due to its relatively low heat content. When removed from the ground, it contains a very high amount of moisture which partially explains its low carbon content. Lignite is mined all around the world and is used almost exclusively as a fuel for steam-electric power generation. The combustion of lignite produces less heat for the amount of carbon dioxide and sulfur released than other ranks of coal. As a result, environmental advocates have characterized lignite as the most harmful coal to human health. Depending on the source, various toxic heavy metals, including naturally occurring radioactive materials may be present in lignite which are left over in the coal fly ash produced from its combustion, further increasing health risks. Characteristics Lignite is bro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coal Mine
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a 'pit', and the above-ground structures are a ' pit head'. In Australia, "colliery" generally refers to an underground coal mine. Coal mining has had many developments in recent years, from the early days of men tunneling, digging and manually extracting the coal on carts to large open-cut and longwall mines. Mining at this scale requires the use of draglines, trucks, conveyors, hydraulic jacks and shearers. The coal mining industry has a long history of significant negative environmental impacts on local ecosystems, health impacts on local communities and workers, and contributes heavily t ...

Tonne
The tonne ( or ; symbol: t) is a unit of mass equal to 1000 kilograms. It is a non-SI unit accepted for use with SI. It is also referred to as a metric ton to distinguish it from the non-metric units of the short ton ( United States customary units), and the long ton ( British imperial units). It is equivalent to approximately 2204.6 pounds, 1.102 short tons, and 0.984 long tons. The official SI unit is the megagram (symbol: Mg), a less common way to express the same mass. Symbol and abbreviations The BIPM symbol for the tonne is t, adopted at the same time as the unit in 1879.Table 6 . BIPM. Retrieved on 2011-07-10. Its use is also official for the metric ton in the United States, having been adopted by the United States |
