Rock

sitegrader

I'm following up a thread I started back in Oct 07 about a large rock excavation (North Texas limestone) project I was bidding on. We are on the tail end of the project and everything couldn't have gone better. I made a last minute decision to try something different and it's really paid off. My initial plan of attack was to utlize 2-D-8 rip tractors, large excavators and 6X6 end dumps to rip, process, and haul the material.

I opted to try the 8 foot wide Iron Wolf machine. We were able to take a single machine (looks like a milling machine on major steroids) and in a single pass, grind and puliverize rock 8 inches deep. The material we produced was typically less than 2 inches in diameter. The harder the rock we encountered the better the product we produced. After the rock was puliverized, we were able to pick up the material with scrapers and utilize the material as select fill on building pads. With the single machine we averaged processing around 3,000 cubic yards per 10 hour shift.

For once in my life, this blind squirrel found a decent acorn.

Right on! Good to hear how well it worked out for you. That sounds like a really interesting machine/project, have you got any pictures of it?

Nice going Sitegrader.

At 3,000 yds per day, were you able to make the completion time of under 60 days?

I hope you made good money on the project.
The cost per yard you were talking last October, makes us guys in the East shake our heads.... But we work postage stamp sized projects compared to this.

Don't take so long between posts for crying out loud.

And post a photo or two if ya got em.

Did you rent this machine or purchase it ??

What loader was the attachment on and how was it on fuel ??

Also, how was it on breakdowns ??

I am assuming that this would be a good investment in the fact that you do not need a crusher. Were you able to use the material for pipe bedding or sub-base for under the asphalt ??

Got any pics ??

I'm trying to post a reply with either pictures or url's to photobucket but I keep getting the error message that I can't include url's until I've made at least 15 posts to this forum. If you go to photobucket and search my username, you can see the small album I've started.

We rented the Iron Wolf mainly because your typical salesman makes claims that he can't backup. He said the machine would process this material easily and he was right. The cutter head is mounted on a Kawasaki 95Z Loader with a Cat C-15 (550+ HP) engine mounted on back of the loader which drove the cutter head. The entire unit weighs 96,000 pounds and will burn about 165 gallons per 8 hour shift-Cat engine, loader will burn around 50 gallons per 10 hour shift. The loader has over 15,000 hours on it, and was in good shape.

The machine performed very well and the only problem we encountered was the high micron fuel filters that are on the engine. All of our machines are fueled out of the same filtered bulk fuel tank and this is the only one that gave us problems. The fuel pressures on these new EPA engines are rated at 35,000 psi. I've made good money on this project, just need to finish before fuel gets any higher.

Let me know wheter or not you can see the pics.
