Wonder how quiet it is. That would be the most jarring part if it’s mostly silent.

I wouldn’t think electric motors that large would be quiet. There is also the sound of the wheels as they roll and any hydraulics for steering. Good question though.

A lot of these haul trucks run electric motors already. The wheels have electric motors and the diesel engine just spins an alternator. This just replaces the Diesel engine with batteries.

Yes , you are right. I used to work on them. The wheel motors were huge. If my memory serves, I think they were direct current.
