Yes sir!. You need to be very careful and take it easy working into a rough shot like this. Even big machines like this can break if the operator isn't careful with the machine. Thanks!

Agreed. I know many old time dozer operators whose backs are shot from pushing in rock

Everybody wants to be an operator till their 1st rock job then it's a whole different story.

I worked in a stone Quarry for 10 years, and all the units were older. Lots of hours on a old 9G, 6644 Koehring , 988Bs, and a bunch of old 35 and 50 ton Wabcos, but we called them Wobbles because of how bad the steering and brakes made them shake. It was so hard on those machines.

I’ve got my dozer hand who’s been out with back injury for a week now from ripping conglomerate in the pit with a D10. It is not easy and I’ve got nobody to replace him so i have been operating it since than.

@@PAmining that awful jar when you come off a shelf is just one hell of a compression on your spine. I ran a 977L for a good minute at a block pit and man it was hell on your back bouncing of solid rock..

It is fun! Nothing beats being right up close to the action for sure. That's why I love making videos to share moments like this

Torquemaster that's strange because these are electric hybrid

D11T is built for comfort. This old girl still requires muscle to run! :) Thanks!

Yes sir, easy to bend or twist something when shoving shot rock. Especially with a poor shot like this. Taking it nice and slow will get the job done and reduce operator and machine fatigue

Leave something to make a day with tomorrow and don't beat yourself to death in the process. A wise old operator told me to run machines like I was at home sitting in my easy chair. Works every time! Put the power where it's needed and spinning isn't doing a thing but wearing stuff out faster for no reason.

It all really comes from experience to operate something this big. I was always told a bulldozer operator operates by the seat of his pants ...meaning by feel.

lidsman2221 on older equipment its about knowing the machine. You get a sixth sense how far your blade is. almost like the front of your car while driving. You know how much room you have. Newer D11 run gps to aide in grade control. They can basically get as accurate as a inch. Its very impressive.

Feel it!!!! Got to say this operator is easy on this d11.

All by feel. I’ve operated D9’s and they are almost half the size of the d11 and you basically can only see the bottom left or right or your blade. It’s all by feel. I operate cat skid steers now and even on something small in comparison it’s done by feel

lidsman22 a real operator does not need GPS or machine control he has an ass and an eye for it real cat scanners are a Dying Breed. Cutting grade with in two tenths by your ass and is becoming a lost art.

That's what a D11 is designed for!

Plus, he's paid by the hour

Thank you, glad you like them!

Thanks glad you enjoyed it!

It might be to him, these old dozers are not like running newer ones

yea, he needs some new grousers thats for sure.

@@kenuber4766 She might grip then

No actually all the pre-stripping work on this job is done with excavator and truck. The job is too small for a drag. Thanks!

Sorry not that I know of, best to resort to the original brochures or purchase some historical books written about that equipment. Thanks!

If you run in rock like this or sand 1500 hrs if you're lucky. Rock guards help but its extremely hard on uc.

They must be differnt to excavator tracks, i track all day building rock walls on excavators and my tracks are good on some machines with 7500hrs still

Andrew Wilson I went through a torque converter in 3000 hours in rock like this in a d8

jordan wolff yea u ant pushing and straining ur tracks like a dozer . if u notice the cleats are gone on this machine.

Yes, and not every shot fires just perfectly. This is very common when shooting ANFO

Thanks!

Changing the undercarriage when hours are up is vital for a dozers life. Additionally engine rebuilds, blade repairs, and other good maintenance will keep her going normally keep an old tractor like this going forever.

CAT is a certified rebuild company, all of their products are made to be either replaced with spec or to be remanufactured by CAT themselves through their shop. Tedious in prices but they are passionate in making equipment last a lifetime. Rebuild kits were made for previous years equipment to either enhance ability and performance and allow the customer to have more updated parts. Other companies cant compete with Caterpillar's ability to keep equipment and customers happy

No way, the new stuff just isn't built like these old ones.

PAmining of course not then how would company's make more money now days. they make them more prone to being broken or worn down faster than they use to make things. I remember my dad's dad had a bulldozer back then for over 30 years and it still worked now days you would be lucky if one would work for 5 years without constantly breaking down.

It's rough on every piece of mining equipment blasted rock like that will eventually take its toll on everything

No, the D11N is powered by a Cat 3508

Two words..magnificent machine..

PAmining Thanks. I would have thought they would have had the V12 in there. keep up the great work

I'd really like to hear why you think he's bad?

let me guess JTech you are the worlds best bulldozer operator if your not stop being a troll

I have pushed off lots of blast,man it's a prick of a job,go slow is good or you bust your back or the tractor

best operator yet.

Ed Wu That. Sure is. The. Truth

Good question. There's a number of reasons why a shot can fire poorly - rock geology, hardness, timing error, misfire, direction of shot. Shooting non-el ANFO is always more prone for issues than shooting electronic caps because of the inability to control the timing accuracy. In this particular case, the blasters pulled the material to the center instead of casting it to the open face. This greatly reduced the burden relief which affected just how well the rock would crack

PAmining: Thanks for the post. Brings back memories. My granddad was a blaster starting in the 30's thru 60's. He started off running a "wagon Drill" (pneumatic drill) drilling holes for the blaster for a few years then was trained to handle explosives. I would watch him lay out the holes in a certain pattern, plug the holes with small saplings or limbs he had cut to keep sand and debris out until loading the hole and tamping with a wooden stick. I don't think ANFO was around then or at least I never knew him to fire any. He used high grade gelatin Dynamite with elec. caps(Dupont). Some caps were instantaneous others delay. Probably the Dozer of that day was a D-8 Cat and the quarry folks did not like large slabs as it was all headed to the rock crusher anyway. It was deemed far better to err on overkill (huge blast) and making rubble than leaving chunks which eat up time. The dozer operator here is a real pro-keeps those tracks turning and tries to take care of the machine. Some future operators can take a lesson watching him.

Flickchaser your right with ur comment,operator aint reving and banging the blade N ripper into the rock. Nice N steady is the way 2 go..

dose not matter it all gets paid for and still makes a proffit

so what the money they get for the job more than pays for that.
