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.[1][2]

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 since 1932 was already a daughter company of RWE (but during an internal reshuffle in 2003 merged with another daughter company to form RWE Power AG). Manufacturer TAKRAF generally refers to it as an excavator of the type SRs 8000.

Statistics[]

Bagger 293 is 96 metres (314.9 feet) tall (Guinness World Record for heaviest terrestrial vehicle, shared with Bagger 288). It is 225 metres (738.2 feet) long (same as Bagger 287), weighs 14,200 tonnes (31.3 million pounds), and requires five people to operate. It is powered by an external power source providing 16.56 megawatts. The bucket-wheel itself is over 21.3 metres (69.9 feet) in diameter with 18 buckets, each of which can hold over 15 cubic metres (529.7 cubic feet) of material.

It can move 240,000 m3 (8,500,000 cu ft)[3] or[clarification needed] 218,880 tonnes of soil per day (the same as Bagger 288).
