And if you could just harness all the noise to the drive axles you might just have something.

as far as I know GM built the first diesel electric rock truck in 1973. the Terex Titan 320ton rock truck. In service from 1974-1991

used a GM EMD16-645 3300hp locomotive engine. quite literally they pulled one off the locomotive line and stuck it in a truck. with a 10 pole AC gen. that sends power to traction motors at each drive. Operating gvwr was 1.2 million pounds.

Ugh just looking at that thing gives me the heebie jeebies. I don't miss working on mining equipment. Although it is pretty cool to see a haul truck carrying 400 tons of material flying down the haul road, makes the ground distort a bit.

almost all terex used the dd engines. that is why you do not see any terex toys. if you place a terex toy on the window seal. there will be a puddle of oil under it the next morning

Where were the Terex trucks built? I think it was in Peoria,Il. not sure. The truck you have posted is the same size as the Haulpak 830E they also bult a 630E and two smaller mechanical drive trucks. I enjoyed climbing around on them and learning how they operated so I could write the repair manuals for them. Biiiiggg Honkin trucks!! The Dresser division was the original LeTourneau(sp?) something then Wabco Co. (Westinghouse Air Brake Co.) They started building electric steer pans powered by DD! You had to run them wide open in order for the electric steering to function. If you didn't it would burn the switch contacts

I love it!

They may not have done it quite on that scale back then but I believe that R. G. LeTourneau pioneered the diesel electric truck back in the early 1050's. Check out the writeup about his road train. FWIW, apparently his 1953 Tournatrain was Cummins powered. "VC-12 Tournatrain, which consisted of a power truck with a 500-hp Cummins VT-12 engine, and three 20-ton trailers. Each wheel was powered by a separate electric motor, four to each vehicle, including the locomotive. First tested in February 1953, after several months of testing, a second engine was added to the rear trailer for more power, and an additional four "trailers". The new version was completed in February 1954, and supported a maximum payload of 140 tons."

Very interesting info 12valve. I remember going through a storage attic in my office building at Dresser and finding old manuals for LeTourneau and Wabco equipment. From what I understand the man was a genius when it came to electricity and putting it to use.There is a LeTourneau university in Texas that has a degree program for pilots. I went to church with a young man who graduated from there with a commercial/private pilots license. Just a note on the Terex. I am not positive on this but when I was at Dresser I remember a co-worker telling me Terex was started by a former Wabco/Dresser employee and they were building the Terex trucks just west of Peoria,Ill. I don't believe they are in business any more. I have been out of the off road/mining business for 20 or more years so I don't know who bought whom and who is who.I still have a friend at Dresser who is the manager for their technical publications.
