This wasn't the only big wheeled dozer at that time. There was a V-CON, and I think it came out as a prototype wheel dozer. If I remember correctly, it sat high like the Melroe and had 4 wheels. The name stood for Vehicle Construct- ors and was a div. of Marion Power Shovel which be- came Dresser Ind. owned, later it was called(INDRESCO).I think the power unit was a 12V- 149. There was also a prototype mine haul truck from V-CON that had 4 abreast wheels front and rear, like the KRESS coal hauler has on the front.The power unit was an ALCO locomotive 8 cyl. engine.Remember back when the Terex Titan,Unit Rig Lectrahaul & the WABCO 3200 were made, big power was the ALCO and EMD engines, way too heavy for the vehicles and only about 900 r.p.m.'s.
This a beast at 112 1/2 tons . I would think a great machine for what it was designed for (but) not so versatile outside that . Afraid to ask the price tag .
Try an get 8!mph out of a d11 or compaction their getting with the m880 not to mention u could replace all 8 tires for half the cost of an undercarriage oh a conventional dozer an that's just what u would be doing if u tried pushing long distances all the time
...purchase cost, maintenance cost, engine rebuild costS, transmission costS, drive system cost, fuel/consumables cost... These things certainly had some VERY specific advantages in VERY specific use cases(the biggest mines on the planet pretty much) - but it's hardly shocking that they long went extinct quite a long time ago. These things had some very significant disadvantages that the vast majority of dirt moving operations on earth absolutely couldn't justify/afford
Tire wear and slow speed - looks more like they combined the worst aspects of crawler and wheel dozers instead of the best. Still, a very unique machine that deserves to exist just because of how neat the concept is.
The 1st line uf yer paragraph, I disagree & Slow Speed? U sed? Didnt cha hear whut was sed by the narrator? He explicitly highlighted the benefits of this wheeled platform over the classical crawler type dozers. Where from the fast duty cycle afforded by this machine results in better gains (from an economics stand point) from getting more earth (volume) moved to where they're intended, in a comparative hour's expenditure* of the same, what was had from legacy systems of old. This (was claimed) translates to greater productivity. Productivity?, Absolutely. Howevr I'm sceptical of the expenditures side, at especially the fuel consumption factor in having 2 engines. Not to mention the encumbrances in having to put-up with not just 1, but 2 power-houses (probably as well 2 sets of drivetrains, I speculate) to contend with & closely maintained, just to keep it in sufficiently ideal, if not the satisfactory most running condition in order both engines work in concert & the vehicle had enuf torque to go about. While I'm uncertain, whether if it had the benefit of having drivetrains that work like those of helis, where if 1 engine gives-out, the remaining is all that's needed to get-by. In helis uf corz, the "Turbine's ECU/M or now better known as FADEC" will in the event of "an" engine failure/power lost-outage, put into effect emergency power gain (beyond settings, what manufacturers recommend, optimal for preserving engine life) in the remaining to compensate for the loss of energy. If it works in the "technical" same, then it's swell, what if it duznt? Owing to a dead in 1, with lesser count of Strathclydes (Hp) to pull, along with the body weight of what's more than that of evn an 'Abrams' MBT, with just 1 other operational engine in service. It tho' probably coud still be driven around somewhat, but doubt it can anymore conduct earth shoving, what it's meant to do. On the 2nd sentence, I'm totally with U, agreeed..

Cab was way ahead of it's time
Ahhh a fairweather dozer, exactly what we need.
Moving one of these on the road would have been a serious pain.
They only made 10 of these. Exceptionally rare.
Second generation electrician coal miner here in Kentucky and i never heard or seen one must have never left WY
Too bad they never made small ones the cab is sweet
Too bad another company hasn't taken over production of this beast. If it were reintroduced in today's market. I bet it would be highly desired.
Is this the unit sitting in a tree row south of Sutherland Nebraska?
Ainda existe esses tratores???

One was fully restored for $650,000. Not for sale - just the price tag it cost to restore it.
Awesome

No way possible that would out push the HD41 Allis Chalmers
Imagine if this was designed as a skid steer
Yes it was, there is no space for the wheels to turn
