Wheel-dozers

[Bellboy]

Well, I think that it is about time that someone ventured into the under traversed terrain of wheel-dozer territory.

Anybody run one, own one, or know a lot about them?

This wheel-dozer is run and owned by Cedara College Of Agriculture. It is a Cat 814B, and is used very seldom. In fact, the last time it was used must have been around 3 months ago, but it is primarily used during silage season to compact and fill the silage pits, as well as towing the tractors out of the pits.
Here are some pics:

The cab looks brand new!

 

[Bellboy]

As I said, it doesn't see much use, so there really is no opportunity for the cab to get to looking used!

And the cab is quite comfortable, actually. None of the rust, wear, or grubbiness of a very used, old machine. It does however need a good paintjob, as the exterior really looks quite rusty. The green bit on the back of the machine is the ripper, but I have never seen it used. It just doesn't look like it can do anything.

We affectionatly call those things "rubber tires". We have a few at our mines, we use them to sweep rocks off the haul roads and clean up around the shovels. I HATE these things. They are handy to have around, but ride very rough. And it's a booger to hold grade with em'. Compared to a track dozer. At our mine property's this is what a brand new operator breaks in on. After several months of running these rascals, if they're doing good, we train them on the real thing.

Ah the good old RT dozer's. Quite a few around here including 2 of the 15 D950's ever made.

RT config is alot easier on the the equipment than in Front end loader set-up.

I can never understand why they put new Op's on RT's? Its a skilled job on the edge when they clean up around 4100's, Dart in and out between trucks's etc.

Weve got an 834B with a B-G behind in at our project. I'll try to get some pics of it this afternoon when I go in.

As promised. 834B with B-G. A real handy machine to have around, dragging the haul road, cleaning up under the hoe, push off the stockpile. You really have to be caefull to not run over the tounge when backing up!

The outfit I work for has two of them, one 834b and a komatsu that is about the same size but i'm not sure the model number is. Both of the wheel dozers are mainly used to push scrapers when we are running in good ground but useless in the mud, which is why we only have 2 of them. The last job I was on we had a 10n with a pushblock and a komatsu wheel dozer. Most of the job the rubber tire was parked because of soft underfoot conditons in the pits and we wound up using the 10. Out of the 12 proposed borrows we used 9 and only 2 of those had good dirt. In those 2 pits that had good dirt we had the 10 and a 8 ripping and the rubber tire pushing buggies. When the rubber tire was pushing scrapers through the ripped material it was loading as fast as the 10 but what got me was how fast it could back up to punch the next buggie through.

First time posting pics...This is from the Vulcan materials plant.

Lot of cladding on that 834 blade. I like RT dozers, always have. Wonderfull for pushing snow and gravel, loose fill. Not so good for excavating hard park dirt or clay or in wet conditions. Great for clearing trees and stumps, building rough haul roads and general pioneering. Very fast in quarries, mines and pits for cleanup. Easier riding too than older dozers. Never pushed scrapers much with them though.

I've spent more time on a rubber tired dozer than I'll ever admit to.
The newer 824's were more operator friendly than the A's.
But IMHO, the A's are still the best RTD Cat ever made.
These pics of me were taken in 1986 by one of the best dirt foreman I have ever had the pleasure of working for.

Tiger 690D

How about a Tiger. Based on a 992 wheel loader . First released in 1981 in Western Australia. Probably used mostly in the mines, a good cleanup machine and pushing dumps with the right material. I think it can push nearly as much as a D10, if its got the traction . This one is stick steer.This is their web site .http://daak.com.au/pages/tiger.htm
Does anyone know of any elsewhere in the world?

If I hadn't become Guy F Atkinson's go-to guy for 834A tranny park brakes on the Upper Stillwater Dam in Delores, Colorado, I might like them more. The operators couldn't catch up to the KW Dart belly dumps from a standing start so would lock the park brake and torque the transmission converter against the brake with full thottle. The belly dump would go by, the brake would fly off and the 834 would jump to the stinger for a push up the face. Trouble was, it was very hard on the park brake and Atkinson had four or five of the dern things. My helper Roger and I had a couple in the shop the whole time that summer pulling brakes out and stuffing them back in. It's a good thing Roger didn't mind working upside down, he did most of the work in the black hole we called it. I'd stuff him in the hole head first and hold his legs and rotate him around as needed.

These machines could be a killer. Atkinson had a guy hurt or killed in California that summer when a rear planetary wheel set blew off as the wheel was being disassembled. The wheel studs were weak and often loose and unless the tire was deflated it could and would blow the planet out of the gear case.

I liked the Michigan 280 & 380 RT dozers better.

2 Of them here, One is home made with d10 Draft-arm's and blade. One big single lift cylinder.

They have problem's but 91'000 hr's on them, they own nobody nothing.

3412's Sound sweet.

JDM is that the quarry of off South Blvd, right beside 485? If so I about got ran over by that same machine.

hey any chance of a pic or ten of them mate?

The first 690 Tigers had a single 992B lift cylinder as the blade cylinder and then they went to twin D10N cylinder and controls for the B model, they also ran the 773B lock up torque convertor and this roilled over into the 690D.

The 790G was based on the 992G and featured D11 blade cylinders etc and the first machine off the line was displayed at Minexpo 96. this machine was then shipped to Australia and i assembled it for Thiess at there Mt owen mine in late 96

I may well be completely wrong but I always thought a 690 was based on a 990 not a 992 (???). We had a 844G that was based on a 990 and a 854G that is a 992G (always thought they used to be a 690 and 790 ??) Rod

 

[Gavin84w]

Muddy,690 has always been based on the 992 c & d. 790 was the 992G and 590 was the 844.

If you can think up a good contraption made out of Cat bits you will be brought out and make a pretty penny on your design.

Just look at Mr Tiger, Mr Elphinstone and Mr DJB in recent years and MR Russell (Graders) and Mr Trackson (Traxcavator) in years gone by.

Mr Haulmax is next in line
