I like the idea of these smaller crushers. I think that at some point the cost of fuel will make onsite material processing more profitable than trucking old material out and new material in. I am would be curious as to what the anticipated cost per hour that skid steer attachment runs at.
I've been thinking more and more about this. I do about 30% of my work doing driveways and site pads. Nothing fancy, just crushed base or doing rehab on an existing road. I clean out ditches, grade caliche roads, and in the process, pull up a lot of rocks. Our limestone is endless.. I live on a virtual rock farm. About 15 years ago, I would use a Rockhound to pick my fields and trails clean. I loved that attachment but it was flimsy and high maintenance if you hit a rock over 6". It was amazing, though.
Looking at that portable hog, I can see it having it's place if it could be used like a bucket to scoop up oversize rocks after grading a road or cleaning the drains. I envision spreading the material (crushed and mixed) into low spots, then running the compactor over it. Since a lot of old ranch roads are made of caliche that gets soft when it rains, mixing rocks on top like would be a good way to make the roads all weather. I can also see this being used to lay a gravel course before putting down 3/4 crushed base which I've found usually needs something hard under it. I want to get into demolition more, too, and crushing rocks, cinder blocks, and bricks would be interesting. If I work with a small trucking company, 1 or 2 trucks, and a lot of my jobs are in tight spaces anyway, I am only getting about 13-26 tons an hour out of my job sites anyway. Living in the boonies it's a long haul to the pit and dump sites.
I'd like to demo one vs the rock crusher from FAE. The FAE thing looks like a great tool for a CTL or skid but it's about 2600 lbs, needs high flow, and throws material. It's probably more productive but more limited in that you have to crush the material when it's laid out. Would be useful in a field or after rough grading a road but it doesn't seem as practical on a building or demo site.
