106 Struck capacity is defined as: The volume capacity of the bucket after it has been struck at the strike plane. The strike plane passes through the top back edge of the bucket and the cutting edge as shown in Fig. 7.1 (a). This struck capacity can directly be measured from the 3D model of the backhoe bucket excavator. On the other hand the calculation of the heaped capacity is …

BUCKET WHEEL EXCAVATORS FOR HARD …
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.

Bucket-wheel excavator - Wikipedia
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 …
