Two D11R Carry Dozers.

[bigiron]

I call on a coal mine every week that uses these two D11R Carry Dozers. Each one can move 57 cubic yards of material.

WOW!
I burn just over 2 cubic yards of Anthracite per winter to heat my house. One D11R can move enough coal to heat my house for 25 years! Thats putting it in perspective!

How many BTU's in a yard of coal? I know it depends on the type, grade etc., but just wondering. Not sure but it seems I remember maybe a cord of hardwood might contain ~25 million BTU.

Thats nothing!!!!! my D2 can move a 100 yards!!!!

(A ball of yarn, that is,LOL!!!)

To help me picture 57 yards, how many yards in a 80,000 fully loaded truck?

That's two big hammer knockers----------can't answer Mike Mc on the 80,000# truck; but here is a 24 cu yd dirt pan working on a landforming project---------seems like the tractor in these pictures was pulling a little over 400 hp.

So-------57 yds would be slightly more than twice this scraper's capacity.


How much HP on the D11R's----------and what would they weigh???

No doubt----------you've got the right handle (bigiron)!!! thanks for posting

Mike-

80,000# truck probably might have a payload of ~60,000# (if it has a lot of aluminum in its construction). 60,000# = 30T. Dirt can weigh 1-1.5T per yard, gravel ~ 1.5T. 1.5T/Yd would mean a 57 Yd push might weigh 85 Tons. Coal would be about 42 Tons. Dirt = maybe almost three trucks, coal about 1 1/2 trucks.

(These weight values from 'Moving the Earth' by Nichols, Jr.)

I pull a 39' frameless aluminum dump trailer with a Freightliner Classic. My max payload is 46,000lbs. at an 80,000lb gross weight.
Hope that gives you some perspective.

[daron]

My payload was apparently off by 25%. Multiply the 'truck' numbers by 0.75 (3/4).

11's are 850HP, 115 Ton +-
