A typical bucket has a volume ranging from 40 to 80 cubic yards 30 to 60 cubic metres , though extremely large buckets have ranged up to 168 cubic metres 5,900 cu ft . The length of the boom ranges from 45 to 100 metres 148 to 328 ft .

4 Types of Excavators: Which One You Should Choose

For example, the power consumed by digging 1 m of soil is 0.50.7kW for singlebucket excavators and 0.30.5kW for bucketwheel excavators. Appli ion range: Bucket wheel is especially suitable for highefficiency mining operations in large openpit mines.
