Abstract
The present invention relates generally to the field of positioning mechanical equipment, and particularly to the likes of mechanical excavation and electric mining shovels. In one embodiment, there is disclosed a system for calibrating the sensors that measure hoist and crowd motions for an electric mining shovel, enabling the position of a bucket to be known with greater accuracy than can be achieved using previously known approaches.
