This paper studies the progress made by hydraulic shovel manufacturers over the last few years, particularly in the areas of productivity increase and operating cost reductions. Five years ago, it was widely considered that the unit production cost for a hydraulic shovel in a mining application was double that of a cable shovel in the same application. The hydraulic machine manufacturers have taken up this challenge, and modern improvements in design, coupled with changes in maintenance techniques, have narrowed the gap to the point where it is valid to ask the question "will the cable shovel exist in ten years' time?".
