Hydraulic Bucket Wheel Excavators - Design and Performance

For more than fifty years the continuous working bucket wheel excavators have been manufactured by O&K. The development in the past decade gave on one hand the giant machines with a performance up to 240.000 m³ bank per day, on the other hand the full hydraulically driven standard types. The design of the hydraulic bucket wheel excavators with their operation and performance are described. For many opencast mines with middle or high output requirements, the hydraulic bucket wheel excavator is an intresting alternative to other methods.
