Off topic, but looks right to me

Hi, 83Jim.
Yep. I've seen that one before, Did you notice the brave soul who jumped of the back of the dozer when it was just on the bridge and leaped back on when it nearly right across? D'yer think he'll get an award?

Just my 0.02.

That looks like a a bailey bridge with four rows i reckon its a lot stronger than most people think

Paul

That bridge will never be safe again! lol What was the guy in front looking for?, bridge mice? lol

I think that was one of those Dat diesel electric dozers from the sixties,I would not say the driver was a hero but he was sensible,just as well it tracks straight
AJ :cheer2:

have a look at this and you will see how strong these types of bridges are

I think the blokes might have been guiding the dozer not off it because they are girly men theres not a lot of room for error side ways on that bridge

I have never heard of a Dat dozer ? Is some one making me look like a silly bugger you dont have to try hard to make me look silly 😖mile:

Hi, Paul.
That dozer on the bridge is a DAT or DET diesel-electric drive machine, probably a 330 model.

Cat like to trumpet about their 'new' D7E diesel-electric drive dozer but the Russkies have been building diesel-electric drive dozers since 1961. The 2 most common brand names have been Dat/Det and Chetra. Their first one, the 250, has been upgraded quite a few times and then superseded quite a few times Until tjhey now have one, the 800, that is almost the equal of the D11R, 800 hp and 106 tons.

I don't know about the latest versions but the all the earlier ones were DC electric drive where the D7E is AC induction technology, which seems to be somewhat of an improvement. That said, all the feedback that I have had indicates that these diesel-electric Russkie dozers were the last things left running - and working - when it got REALLY cold.

Just my 0.02.

thanks for that Deas I am surprised DC traction motors werent successful huge traction even at zero rpm 100% torque and DC is easy to control as well but like all these things there is always more to the story

Hi, Paul.
I don't think it was that they weren't successful - just overtaken by better technology.

Here is a link to their 'big one'.

Enjoy.

Just my 0.02.

There were a few of those machine here in the UK in the mid sixties,that was the first dozer I came across with a proper fitted cab that had wipers,heat and defrost for the Russian winters,they also had fuel warmers,one near me was working at a landfill and it seem to be doing ok,the Russians had diesel electric ag tractors back in the 1930's,probably easier to put in an electric motor than a mechanical transmission.
