OK, perhaps I don’t fully understand the process. I have never seen a rock crusher/mill on top of the dirt/rock pile before. Typically they have this piece of equipment on the ground and the loader/excavator will bring the material to it. My concern is the fact that the excavator is digging out the material beneath the crusher…just my thought, but don’t you think that might be a bad idea?
On another note, Caterpillar has a great web based resource on safety with construction equipment. If your looking for videos, toolbox talks, or other training material check it out.
