Re: Shovel mechanics
You are probably right about gravity being used to let the boom down. But the dipper handle needs side back to start a cut. I'm not claiming to be a expert on cable shovels, just trying to share what I have observed.
A rack and pinion mechanism would probably be easiest to 3d print and the most straight forward as you can have a motor direct drive the pinion.
