7495 HF WITH HYDRACROWD

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.
