The bucketwheel excavator (BWE) is a continuous excavation machine capable of removing up to 12,000 cubic metres per hour. The most favourable soil and strata conditions for BWE operation are soft, unconsolidated overburden materials without large boulders. BWEs are widely employed in lignite mining .
Bucketwheel excavators (BWEs) are continuous mining machines for overburden (semihard material such as clay, sand, gravel, marl, etc.), lignite and hard coal. TAKRAF BWEs can be employed across a widevariety of commodities and our machines .
