D9T Transportation

[Mrsmackpaul]

yeah sort of the push arms are inboard the track frames with a tiny blade yep makes sense a narrow blade for pushing scrapers

Hello All,

I am new to this site so fore give my possible mistakes.

The pictures of the D9 on a two axle trailer being pulled by an MAN 6x4:
If you pull the picture really close you can see a decal on the bonnet in front of the cab which suggest D-T, the number is hidden by the safety ballustrading. So this could well be a 9T or even a 8T.
The trailer although only tandem axle has wheels the full width on both axles and is very typical of early American heavy transport trailers and also as used frequently by the military. Of course such trailers are now barred in the EU, UK, and America and all must be multi axle etc, etc.

It is an interesting post and I look forward to reading more.

Having been in heavy plant most of my working life and bought up in it I have seen a lot of changes over the decades but the older machines from the 1960's and 70's are still in my view the most fascinating.

Like I said I would probably make some mistakes getting used to this forum!!

The pictures I refer to are the first post from Dave showing the tractor on a red tandem axle trailer.

Sorry for any confusion.
Paul.

Dunno about a D 9 or D 8 only thing I noticed the track gear all fits on the trailer but like I said I dunno much about it all

Hi, Folks.
I think it would be a pretty safe bet that the float with the D9T is somewhat wider than a normal road-going float as a D9N, R or T would have the tracks over-hanging a normal float deck. I'd venture to suggest that it is a site float and they are simply carrying the machine from one part of the site to another to minimise track wear and save time.

Hi, Paul.
As Bigkit said, that D9L blade is a cushion push blade designed for picking up scrapers to push load them. The rubber cushions, in good condition, are capable of absorbing the shock from up to about a 5 MPH contact speed, although it is not recommended that the push cat operator make a habit of doing that.

Funny thing is, with scraper operators who KNOW how to pull in correctly and stop in the RIGHT place and a push cat operator who knows what he is doing, it IS possible to pick up the scraper with a semi-U blade at FULL throttle in second gear and NO bump.

BTW, the D9L has about 15 tons on the D9N and R and about 10 tons on the D9T. The D9N and R are both lighter and less horsepower than the old D9G. The D9T has finally made it back to similar weight and horsepower as the D9G. PROGRESS??????????????????????

Just my 0.02.

Thats really interesting - never knew that the newer D9's were less powerful and lighter than the D9G!

I remember watching a Komatsu D375 pushing 631's years ago - the dozer turned too quickly and caught the rear tire. It exploded big time!

Thanks for the welcome guys, it is interesting reading the views and new information, we are never to old to learn!

We used to run 631B's and I found the most sensible tractor to push was a Komatsu 155, slightly heavier then a D8H 68A and a bit more power, the gearing suited well also. We also had a 355 with ripper and although a cracking ripping tractor it was cumbersome for pushing the scrapers and really a waste of resource and fuel.

All the best
Paul.

Nice perspective Paul
