In 1970, O&K Orenstein & Koppel AG, Germany, introduced one of the largest hydraulic excavators in the world, the RH 60, an hydraulic excavator with a 9 yd3 face shovel, or a 6 yd3 backhoe attachment.
The machine proved to be a productive and reliable tool even on field applications unknown for hydraulic excavators before its introduction.
Major features of the machine, its basic design, and examples of field applications are discussed.
