Look at the Cat® D7E Mid-Sized Dozer - Inside and Out

[@iamwilliamb]

I like the exploded view when showing the new power train. As a former ringpower technician and shop manger I would recommend making sis web parts work the same way. Click on the group it opens up. Click on the part and there is your part number. I wished sis web would be like that forever. It looks like cat now has the ability and the input. Help the techs working for the dealers and you will see a lot of happy techs.

[@smacman68]

We rented one of these on our last job, and I had the joy of operating it. I was skeptical about the torque when the blade really dug in, but I was really surprised. It knuckled down and pushed right thru hard pack with the ripper fully engaged and pushed a 13' pile of gravel as far as I wanted. And the cab is so nice. Very high tech. Smooth operation, quiet, and air conditioned. I'd buy one of these right now!

[@judderman37]

I remember Terex used to make dozers like the D7e, but without the electric drive, its got the single lift cylinder for the blade so since Cat bought over Bucyrus who bought Terex they would have access to the technology of previous machines and start from there!

[@teamlaguna]

YOU GO CATERPILLAR ... Nice to see that you all have combined EMD & Progress Rail together with your selfs .. It is GREAT to see the merger of such GREAT American icons !!!

[@doriancrosby6850]

pro tip: you can watch movies at flixzone. I've been using them for watching lots of of movies these days.

[@deshawnelisha3331]

@Dorian Crosby definitely, I have been using Flixzone} for since december myself :D

[@hermanwieler]

Yea, our local dealer showed one today and the salesman say around 600,000 price tag

[@simmonsalinas]

I wonder if they could still implement the elevated drive sprocket on these guys.. and I'd love to see them making bigger dozers with this tech...

[@txpipeliner07]

We have 7 of them and they stay broken down more than they run. Most of ours are around 5000 hrs. Our mechanic can't fix the generators or the drive motor. That usually means that we have to haul them to cat and it takes about a month to fix. On top of all of that none of our operators want to run them they will beat you to death in rock and the blade control isn't operator friendly like cats other dozers. There is only one thing I like about them and thats the air conditioner. Hopefully we will get rid of them soon and upgrade to the new high track d7.

[@CatProducts]

We're very sorry to hear this. Please send us a direct message with your name, email, phone and location and we'll send your information to your local dealer for further assistance. - Manuela

[@taylorstasny1017]

Exactly what we were wondering, every unit we see for sale has 3,4,5k hours no high hour machines out there hardly. When it breaks down your at the mercy of Cat and if your not their biggest customer, get in line buddy lol rather stick to R, T, or H models seems like.

[@emmettadventures5704]

It is breakthrough in the industry. It is the first electric drive dozer.

[@rossgray3070]

Its obsolete now, the new D 7 has gone back to Hi Drive and conventional transmission, was on show at Conexpo 2020, wonder why.

[@jackG622]

why has the D7E gone back to the conventional track system,very interesting,time will tell if this dozer has the reliability,electronics seem to be a lot of the domntime on the newer models,where has cat been,Le Tourneau,Wabco,GE,have had this invention out since the 1940s,one blade ram,Terex done that,hybrid technology me ass,they have made electric powered dumptrucks,shovels,etc for years,cat has only just got on the band wagon,will this 7 be tuff enough,

[@blakedigsdirt]

Letourneau pioneered electric drive systems and they have been around for decades, Terex's single lift cyclinder since the 1960's, and Deere's tilt cab. I did see the put their shitstem 1 undercarriage on it though...

[@leewatkins1610]

Letourneau used the electric idea In the 50s...amazing it took so long for cat to embrace it.maybe its because it is a bad idea.but maybe the early ones were poor because they were before their time because something was not yet in place..like metallurgy or some electric tech.Time will tell...economics may destroy it.or it may be the future.letourneau had electric steering also.this is now common .but early electric steering killed people.

[@jareddrummer1]

As a diesel mechanic it's easy to see that they are just making things harder on everyone all this EPA crap is ridiculous anymore... Glad I live in Kentucky we don't keep up with that crap our law enforcement have cummins trucks that smoke ya out

[@JTyler52]

@samfromportadown Not really, its very hard to make heavy duty equipment, 18 wheelers, earth movers, etc full electric, because although electric is cost efficient it doesn't create the amount of power the things need, or it could, but would drain itself pretty quickly. Most trains also do the diesel/electric because its powerful and cost efficient.

[@everburningblue]

I was an M1 Abrams crewman once upon a time. I couldn't imagine changing track on that monster. Have fun with that......

[@flyinasscritter]

how is this break through - trains use this - and now its being put in cause diesel is outrageous nowadays - could of done this many many years ago

[@danielkennedy1524]

Advertising Well, dollars to donuts that thing is twice the price! Also, is there a study the general public can read to see where those stats come from.

[@brittfarms2018]

imagine the money that will be saved by this machine. thats a real slick machine.. but the price tag will be high..

[@M24A6]

Approx. $750,000

[@Giggidygiggidy12]

Anyone know if this hybrid technology is available on a larger model like the d9 ?

[@DVeck89]

@FireAce44 It would but the way cars are now, there's more moving parts, more parts you need to replace, etc.. parts and stuff that car companies make money on. Why would they make something that would earn them less money in the long run.

[@danielkennedy1524]

What is the initial cost however? A truly brilliant concept. Bucyrus Erie and Terex now Cat.

[@rokn50s]

i tested this badboy in orange county ca it was smooth

[@ariels36]

The electric drive system is similar to the way diesel-electric locomotives work. Right?

[@pablosupra4097]

Zajebista maszyna ciekawe czy jest wersja LGP

[@Thuging2myDeath]

Thats the future right here!

[@cletrac12c72]

$5000+ to replace the engine coolant pump! Dont see low owner/operator cost savings there! And mice just love to chew on wires!

[@vanjohnston1797]

I imagine that it has a muffler on it unlike the original.

[@beerdeddi1]

Why has this dozer no deltatracks?

[@FCEBKconcealedweapon]

its double as expensive as regular dozer currently

[@kenneththompson6543]

Only thing I don't like about it is the 1 hydraulic jack in the middle for the blade

[@Ept44]

how much do these machines run?

[@mphepg]

240p resolution?

[@samfromportadown]

If they made an all electric version with no diesel engine, a big battery instead, and an additional high power motor to handle the hydraulic pump duties, you'd have a machine you could literally use to build the moon base.

[@Raxarax]

@hermanwieler that's surprisingly not bad...

[@alanack67]

There is nothing wrong with a diesel electric hybrid bulldozer. Locomotives have been using that system for years and they are some of the strongest ,machines on earth . While old systems may be simpler and easier to work. We need to preserve resources for future generations.

[@mikescaffo4850]

I want one I don't understand why because I don't need it but I still want one

[@flyinasscritter]

well they should of been looking at trains a long ago - diesel / electric motors are the way to go -

[@judderman37]

The design is nothing new, its a copy of an old Terex dozer when it was owned by GM in the 70's

[@asherdie]

That stole from R.G. Letourneau which still uses this tech.

[@HEOEvgeny]

There is always a trade off.You cannot get something for nothing.

[@Ghostrider2999]

neat, yes we get it combovergi,

[@cutandshoottx]

i'll take the old one's. not some thing the EPA made cat build

[@bugmandu1]

Three word's High Tacks Rule!!!!!

[@sasop117]

exactly its the way forward i think

[@13lael]

The TRAIN !... bad ass !

[@FCEBKconcealedweapon]

costs $600,000

[@pelagic6]

Wow, diesel electric drive has only been around for 50+ years...

[@Tomthetoolman100]

cat build fantastic products there best is there engines there is no better but i think we need to leave the electric drive to Hitachi

[@kelleyhooper3621]

Ridiculousness! Terex? Come on! Not even close. This unit will out power a D8T with the correct tracks.

[@panicoenduro]

simply beautiful !!! but I think is not way for my boss to buy a nice things like this =(

[@christophers1247]

this is not a new technology some front end loaders and forklifts have been using this kind of generator drive system for years also some larger excavators.

[@Billy982810]

sooner the high track phase is over with the better.

[@biutlere]

its weak will never stand up. i have 30 plus years and have sat in one it will not stand up to others

[@eastmoaness]

ROSS WADE IM WITH YOU .65P WOULD PUSH IT OUT THE TIP....

[@Sojourning_]

Good day Gentlemen" Lete see if I have this right" Initially the 4 cylinder D-7E by design was a Military engineered design with special high end features unlike the Industrial Commercial equipment: such as the torque & such: Listing to the video:vary impressive talk up with the cat; I actually like the seeing the Cat didn't get screwed up with a high track arrangement" In fact I had ponder how long it would take before cat would reproduce a new designed of D-7E: I could be wrong with this; you may or may not have anyone still on board from the early middle 60-s when I was cutting my teeth on Cat: I was getting broke in on the 2-U D-* & the-9" some had a wood floor deck: what a kick; TD 26 International was sort of still the machine, but had falling way behind when cat broke out with Hydraulics: The short of it: The D-7E I knew in side out back in the middle 60-s when it came to Vietnam: I was with the 27th Roman Plows: I know there are several around who had made all sorts of claims to fame with that" fine with me: I spent my years cashing that yellow Iron" iif was about moving dirt I worked on it" trained up on the 641 A cans: talk about a small dirt moving scraper: we had them" The 666 kept me going" I cashed it in; walked away, retired early on; age 50: in fact it's been even long now; Worked for some of the high rollers from back in the day moving dirt rock & what ever else was in the way so swing could come in & build: Don't screw it the D-7E; keeping the undercarriage is the way to go unlike the other high tracks: I run the 1960 models through all kinds of hell back in the day: although I ran over a many my self,one fellow in the lead plow tagged some thing 20 21 land minds & walked away every time: That old wish bone A_Farm open V bottom out was saved our lives: directing the explosion out the sides away not directly up: The rang tarns is what made up for the rest: It was a sit to see the floor plates puffed up" although those rubber hose's didn't cut it: for the blade: it was in your face: Some times as long as the an RPG didn't hit in such a way a person was about half OK to come out of it with nothing or some thing but still alive to tell about it: that was about the only thing that could do more damage then the land minds on a D-7E we ran them so hard every day the turbos all but melted down\; they glowed like moving water they were so over heated; & that was during day light: I seen those 4 bangers run all day on near no water: day in & day out: the heads leaking oil & water coolers blistering hot; so hot it was impossible to touch them: Blistering hot" water oil bellowing out the exhaust: The exhaust at times for some were blowing flames of fire, it be like that off & on all day" fires break out in the pans: Oil soaked brush burn that Little cat to near death: the next day fire it up as long as the lines were still on it & put it back to work: We did have a few of them where the farm / body it self had been torn in two / split by a mind: a few tracks Obliterated, basically at the point of impact: other wise we shook it off: set up & kept right on moving ahead: all those who could: So don't mess it up people: it was tougher then most army tanks rolling over land minds even anti tank minds it did vary well with'; but no" you weren't likely to be walking to far after that: that was it's limit: That little D-7E was a war horse" everyone wanted them; the infantry wanted them / us to run point with the Roman Plow: easy to reason why: The D-7E was all about sparing lives like no other machine: Yet we sat upright in a wire stretch metal cage; make shift blast shield on the floor: an up right plate of steal weld to the floor entry way on both sides: sort of worked; at lest one felt better: we had welded who made all of the belly pans rather plated them to help protect us from the land minds they did a great job; You never hear about those guys working all night to put us back in the seat the next day: I seen that goofy looking iron works type cage for an old plow in display: In Nam or any other blistering hot place you be dead in a couple of hours it be so hot in that thing: The later teams who cam in some had water tanks mounted to the top of there cabs for water cooling them down & the cat: Most of us were just kids at the time: crazy days; Don't screw it up: the only real test; run it over a land mind a few times; the only passing of that test is it till in running condition No other test required oh yeah" the cab still needs to be in tack with no fly metal tearing around it inside by the operator: think that nuts: may be so; but there were a few hundred who lived it in real time:

heads up cat: read on

[@tylerg57]

And their ruining their machines with emissions too, i still love cat but they need to wake up

[@Firelife3]

+tyler guill Their making for the future =)

[@tylerg57]

I love cat but their messin up, they ruined the d7 and now their making the drive train electric, come on cat, wake up!

[@SpencerHHO]

Diesel electric drive trains are common place in many other applications they are easier to maintain, use less fuel and have better torque and control. What's wrong with it?

[@Fv_wake_n_bait]

that is a fourtion of money

you just said it your self, she will pay off, unless the op is a slop haha
