Hemmings Motor News Blog

Hemmings Motor News has been around since 1954. We're proud of our heritage, but we're also more than the Hemmings full of classifieds that your father subscribed to. Aside from new editorial content every month in Hemmings, we have three monthly magazines: Hemmings Muscle Machines, Hemmings Classic Car and Hemmings Sports and Exotic Car.

While our editors traverse the country to find the best content for those magazines, we find other oddities related to the old-car hobby that we really had no place for - until now. With this blog, we're giving you a behind-the-scenes look at what we see and what we do during the course of putting out some of the finest automotive magazines you'll ever read.

Like a One-Man Cage Match

Posted November 25, 2009 12:00 AM by dstrohl

After yesterday's post about the LeTourneau road trains, our pal Gary Faules emailed us to share some photos of another LeTourneau with which he had first-hand experience.

Considered to be an "All-Electric vehicle", the LeTourneau skidder weighed 30 tons and had 4 DC electric motors and 7 AC electric motors. The generators were powered by a 280-hp supercharged Buda engine, but the vehicle's top speed was only 15 mph.

That is a very interesting example of a log skidder. It is interesting to see one that used electric traction engines but was diesel powered.

Diesel engines turning generators that run the traction motors has been in use by locomotives since the 1940's. Maybe before.

The diesel electric drive systems have been used on many forms of mining, earth moving, and heavy construction machines for decades. Its only closest rival is the full hydrostatic drive systems which are more suited to the smaller classes of machinery.

For high power with outstanding durability and efficiency the diesel electric drive train has proven itself to be the most cost effective and efficient system for large equipment given its ability to have high torque and power plus full dynamic and regenerative braking with the least maintenance involved.

Auto manufactures should do far more development in using either of these technologies!
