Rock trucks take the high road with the D11 on the low. Not sure if everyone was on the same page. https://www.youtube.com/watch?v=cFz1L0pQ-_E&list=UUBDziNm8KrCQ4j3sv7ozXeA
That operation would not be allowed in a lot of places.
Even if they have good communication, I question backing the trucks up to dump on an edge that the dozer has undermined.
Yeah that's pretty sketchy looking.
The safety issues are obvious and noted. What I don't understand is why the D11 is down there pushing off in the first place? With the trucks dumping so close to edge there is little push off and the D11 wouldn't hardly have work to keep the dump pad clean if it was up top.
