On the flatland jobs you can't really bench up the crushers, but when they are crushing cuts into hills for roads they will bench up the hoe and crusher. Saw something new couple of weeks ago on the way to KC. There was a pipe crew last week that was using a track crusher to make a windrow. They had one hoe sitting of the pile rock feeding the crusher and then a second hoe sitting on the windrow of crush loading end dumps.
If at track crusher is going to stay relatively stationary, i have seen a couple of company's crush some rock us and build a bench out of that to get the conveyor up in the air. I have also seen a few using small stackers if they are going to be moving around the jobsite a lot.
When i was little, 5-6 i got to watch Hamm making a cut for K-10 bypass using 2 track loaders and a track crusher. There wasn't enough room for wheel loaders to make a turn, so they had a 973 with a side dump bucket loading the crusher.
I guess the operators didn't like the side dump very much, so they did a lot of turning on the rock. After destroying a set of tracks the way only a track loader in shot rock can, the foreman got on them. One of the operators got kicked to the landfill pushing trash.
Another 973/963(can't remember) was loading trucks that hauled back(<.5mi) to a mobile plant secondary crusher and screens. They used most of the rock in their mobile asphalt plant, to pave the road, and the rest was sold through the aggregate side. They only had just the one track crusher at the time, so they had to seperate the primary and secondary crushing anyway. One plus was they only had to move the crusher and two trackies every time they did a shot. Downside was all the trucking, but it had to get to the plant sooner or later, and diesel was cheap in the 90's.
