BUCKET WHEEL EXCAVATORS FOR HARD APPLICATIONS

the bucket wheel requires less maintenance than a bucket chain. Also, a bucket wheel excavator digs a block in a terrace cut and is therefore well adapted for selective mining of seams imbedded in the block. Today's theoretical capacities of Bucket Wheel Excavators range from approx. 400 m3/h to 10.000 m3/h.
