This is the first bucketwheel excavator in Illinois, designed by Frank F. Kolbe of United Electric Coal Company. This was an economical method of moving a great volume of soil and shale and depositing it far enough away to prevent the spoil pile from sliding back into the pit. This wheel excavator could deposit to a spoil pile 400 ft away. Bucyrus built the upper portion onto a Marion dragline chassis. The machine weighed about 1,000 tons and had an output of 1,000 cubic yards of material per hour. This volume is about 5 times the rate of the Marion dragline model it replaced. |
