Dozing cemented gravel.

[brantc]

I'm brant and I'm new to this forum.

I'm doing a little mining and before I get started I have some questions about the material that we will be cutting.

The top layers are red clay mixed with gravel and as you get to the lower layer it becomes progressively harder and more cemented.

Here is a pic of the strata.

In the literature the say that a D6 can push about 200YPH over 130 ft or so.

We need to push at least 100YPH.

What does that go down to if you are getting into harder material??

I bet this is the wrong forum... I dont see any cats or big tractors......

The year of the D6 may make a difference. Also the type of blade and if there is a ripper mounted. Track width comes into play also as well as the condition of the Growsers.

Operator experience makes a big difference.


Lots of variables.:thumbsup:

The material doesn't look that hard but if it is, you will need a ripper on the rear to break up the material. How you need to move it makes a difference, if you are pushing it in a slot to dump over a bank, you can get some good numbers easily, if you need to follow the layers and maintain a grade and push the layers into separate piles, your numbers are not going be anywhere close.

If your just hogging off overburden, and getting mixed up makes no difference, it doesn't look like that bad of stuff. A semi-U blade, and aggressive corner bits do wonders.

Again, if mixing makes no difference, you can make the cut at an angle, down across the face of layers. Cut down across the face, push across the flat. As Slowzuki mentioned, make a slot to push in. With a semi-U blade, you should be able to get it to stand as high as the hood, before tumbling over. As an old foreman told me years ago when I first started,
"Moving dirt pushes a lot easier, than just stuck to the blade, carrying it". Looks like it would be pretty easy to keep it just creeping on the blade.

If you can't get your blade loaded up in a short cut, back up, and get another. You should be able to push about twice as much, as you can cut, and push. Just nudge down on the blade as you enter your first pile of cut, and get your load to roll a bit. It's like the tractor will half stop for a split second, then raise up a bit, and move on.

When you feel the ole' girl waddling like a duck, you're pushing all she'll push..!! :thumbsup:
