Development of electric-hydraulic control system for large-sized mining shovel

Abstract

The world-largest class hydlaulic mining shovel has recently been developed by Surface Mining Equipment for Coal Tecnology Research Association (SMEC). To operate with huge weight and inertia, a newly-developed electric-hydraulic control system aided microcomputer processing is adopted, resulting in superior controllability, greater production and better fuel consumption. This paper introduce the abstruct of the shovel which is fully used higher electronics control technologies.
