The D11 works fast requiring only one pass to remove the remaining center ridge. The entire upper plateau was leveled within a week despite the dozer responding to other jobs in the pit when required.
If only everyone who has small brains could understand that slot cutting is the best way to move mass quantities of material efficiently. Too many guys try to chase wind rows all day rehandling the same material over and over. Great clip. Make one showing the process of stair stepping the slots and show how much dirt you can move in a slot.
Are you talking about taking the dirt from the back and using the ‘Chris-Cross Method’? That’s what I was thinking when I saw this video, literally all that dozer was doing was rilling the dirt back into the slots, not actually moving it from the back of the push over the edge. Heaps of time wasted
I worked in earthmoving equipment division of hm eed tirvellore taken over by caterpillar for 18 years The sound of dumpers being run in shop would be heard as background music When i left i had several crores documents of dumpers on my table ready for dispatch.These machines are great to be seen specially when they are shipped in 4 or 5 trailers.
Actually no. It would have taken more than one pass to remove the material from the center ridge because much of it went off to either side of the blade as the dozer made the pass. The center ridge was a product of what is called "slot dozing" which allows the dozer to push more material ahead without losing it off the sides of the blade.
Yes it’s was fun only that guy failed on productivity clearing the windrow of material between the slots a few passes from a angle dumping the material into the slot would have been more productive
Sam's a real genius. The dirt got 'destroyed'. . . . . so I wonder how in the world that could possibly happen. Not only that but he 'FELT SORRY FOR DIRT !!! '
You can see everything you need to in D11’s especially on days! Night shift is a little different but you do get a bit of a rush Bulk Pushing on nights in 11’s. Side Cutting is even more fun. As long as you are aware of your machine and how it will behave youll have no problems😊 Your always looking down between your Blade link arm or out at your blade wing anyways. your almost never looking straight forward.
I got in a 11r and stood it on the ripper tryin to climb a loose fill….carrydozer blade is a beast..you can tell a big difference when you raise one right after a regular blade…never got to take a pass but played on one…
I think the reason some naysayers are missing the point is because they dont know that the blade on that D11 is probably pushing a mound of dirt the size of house.
looks easy in poofter dirt (old mining term ) but in blue rock or iron ore that would take 6 passes easy . been on dozers for 15yrs and d11s for 7 of them . great tractors . either that batter was 15 degrees or less or that dirt was talcom powder
I ran a d11 for amerikol mining from Butler PA,for 11 years before taking a job as mechanic for same co.the catd11 will move lots of dirt but that cat 3508 engine is junk I think we only had one engine last past 5000 hours and it went the full ten thosand hour chain out but the rest would burn out pistons or more over Piston rings some had cams go bad outhers blown head gaskets cracked heads ECT.ect.im not a big fan of the 3508 ,but our d tens on the outher hand didn't break down very much the v12 s both the 3412 and the newer c27 overhead cam engines would run the full ten thosand hour to overhaul without a hiccup just as I was retiring the d11 got a c32 v12 engine the co.just bought one up at the northern divistion .I don't know how it worked out but cat knew of failures with the big v8 ,well enough I'm guess that it promoted a change in engines,guys I talked to that got to run them say thier loaded with power!
I know that looks spectacular but is highly unproductive. When taking out rills between slots you start at the back of the slot and 45 degree push rill into slot utilising the walls of the slot to carry the maximum amount then repeat process using the alternate slot and so on until the rill is gone. Ensure your slots are no deeper than blade depth. This will make for a safer more productive outcome.
I agree. The bulldozer sometimes was there for a long time and other times moved to other required work and not seen at this site for a few days. Really difficult to know when it was working.
@@DigzBig just an idea. In the future if you can, it’ll be nice to see the before and after shots to see how the project turned out. Great videos tho, I can watch it over and over, my children thinks I’m weird watching this monsters at work...lol
Gavin84w yeah. I'm highly disappointed at how few people commented saying that. One guy even called him "a good cat skinner." I came from construction grading to mining a little over 2 years ago and have been largely unimpressed by most of the people who are considered good operators in the mine that I work at. I'm a perfectionist when it comes to my work and I like to think I'm a fairly efficient and strive to always get better and more efficient. It drives me crazy to see the potential of that beast completely wasted by an inefficient, half ass "operator." At least he was actually using slots, but if I had to guess, I'd say he started from the back of it lol.
as a dozer operator I totally agree. The fuel burnt and wear occurring is totally unnecessary. The load pushed over the cliff is the same and the operators spillage was terrible.
Here is a video of the disassembly of a Bruder D11 Dozer... ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-GbD_9zEuPBg.html For all of you interested in making one of your own..
he did not finish the ridge in one pass it is lot of it left . cat advise say push the end of the ridge into the slot an push it down that way in stead spreed it all over
