Here are some pics of the new Cat D7E electric drive dozer from Conexpo. From what I understand they haven't set a price on it yet and production is probably a year away. They do claim some big advatages with this dozer though, like 20% better fuel efficiency and 25% more productivity. One interesting thing I saw happen, while waiting in line, an Asian gentleman got in the cab and started taking pictures. Not all that unusual in itself but he had and exhibitor name badge. Upon seeing this the Caterpiller guy politely and firmly booted him out. He stated something to the effect that they have paying customers that are interested in their dozer and if he would like to come back later, when they aren't busy, he'll be happy to answer any questions then.
More pics of D7E. Here are some more pics of the D7E. These are mostly of the engine, generator, drive motors and switch gear.
More pics of D7E. v2.0 Okay, let's try this again. Here are some more pics of the D7E. These are mostly of the engine, generator, drive motors and switch gear.
More pics. More pics.
Thanks for the pics!! The system makes a lot more sense now seeing the cut away pics!
Great pictures Thanks
yeah, i seen some asian guy photographing the hell out of a large hyundai excavator. he must work for IHI or sunwang or one of those other copycat companies.
Did anyone notice in the engine pics that there isn't any starter ! If it is like hybrid cars they don't have to have a starter.
saw the same thing happen at the deere 544k loader. my son was in line to get in the cab, deere rep ran the asian guy out. son saw the asian guy put a marble back in his pocket he had laying on the dash, and put his notepad/camera in his backpack and left.
I guess just spin the generator to start. I wonder if the power converter stores enough juice to start so extra batteries are not needed. Things are sure changing, glad to see it
It's got a starter.
Good. The Cat guys are proactively trying to stop people from stealing this design... funny that they didn't stop me.
Nice pics to bad the fuel efficiency wasnt closer to 30 to 35 percent better
O thats sweet you can count me in for one of those when they hit the market!!!! i cant wait
Nice!
Ha Ha Ha thats funny. The "Asian" Guy was probably from Mitsubishi. Ross
one lift cylinder?
Really very good pictures, and see CAT D7E is good bulldozer///////////////
2011, My company is looking a D7 sized dozer. I am real interested in the D7E too. THis will be a nice change for us, all we are D11R/T and D10R/t sized dozers. What may be helpful to my company, it the fact that we already have a full compliment of electricans that maintain our four draglines and plant facilities They will be really interested in this machine too.
Love the one lift cylinder, better viability, nice terex cue!
I have seen a single lift cylinder on Cat before. Have seen it on D9G's set up with blade for pushing scrapers.
I don't see an Asian guy in the pics... but I doubt it. The D7E is mostly a Peoria-designed machine. :usa (Though there were apparently a lot of Komatsu people wandering around the D7E booth...)

Is it just me or is that " white module " on the front right handside of the engine an ELECTRIC waterpump ?
Good Pick up.......If I had to guess :- Possibly 2 seperate section of the pump for 2 seperate circuits eg JWAP and SCAC?
Oh so close but we must admit when we are wrong! The C-9 ACERT has a Seperate circuit for:- APC Power inverter Generator Hydraulic oil cooler And of course the Engine has a ATAAC.........so NO need for a SCAC!
