Cat Electric Rope Shovels 7495 HF with HydraCrowd

Cat Electric Rope Shovels 7495 HF with HydraCrowd

Overview

Electric rope shovels have been successfully removing overburden and ore on mine sites around the world for more than a century. Driven by a vision to make these highly productive machines safer, more reliable and even more productive, we challenged the status quo and built an electric rope shovel that's better.
