The VEB Förderanlagen- und Kranbau Köthen is a special manufacturer in the GDR for Bandabsetzer of various types. For example, one of the most efficient settlers for transporting and discharging mined earth masses, type A2RsB 8.800.110, can deliver 8,800 cubic meters per hour. The belt separators of VEB Förderanlagen- und Kranbau Köthen are designed as light but stable constructions in one or two parts according to the capacity. For tilting operation, they are equipped with crawler tracks. The up to 165 m long discharge boom of the spreaders tilt in low, high or dam fill. The use of the belt separators is not only in lignite opencast mines, but also in the tilting of ores, sand and bulk materials with similar properties. The band killers from Köthen have been exported to several socialist countries and Greece.
