looking for info or pics... anyone...??

12-08-2006, 08:46 AM
I don,t have any info on them other than we had one or two come into the dealer one time years ago & they were D4s & boy that was a load for the old D4 without any load in the bucket.They had the steel roof over the operator to protect him & the loader assembly besides that was very heavy constructed.

Man...it would be PRICELESS to run a rig like that.....NOT!

A waste of a good Caterpillar......

Here’s one of a “Athey” overshot mounted on an D8 later 1H or early 8R Series tractor. The bucket size for the Model 8 MobilLoader ranged from 2.7 to 4.5 cubic yards. “Depending upon the type of material.”

I saw a loader in use loading gravel on either a D2 or D4 I am not sure now which since the guy had both with loaders. The one I saw was not near as cumbersome as those others have shown. Maybe some one else will have pictures of the type I saw working it was rather neat and I am quite certian it was genuine Cat. Sorry I have no pictures. This was in about 1958-60.

There was a pretty good post w. pics on the old ACMOC board back a couple years. I don't know if you'll ever find it but you might want to give it a shot. Sorry, I can't remember who sent it in or the subject line.

Here's a picture that came from a web site up in Iceland. Not sure if it's still there or not.

Thanks to all for posts, very interesting stuff.

There is one of those things at the LeSuer County Pioneer Power Association. I believe(not quite sure) it came from the City of Rochester, Minnesota. It was used to load coal for their power generating plant as I remember. What a dirty job that would have been. It's in decent shape.
Merry Christmas

A old Athey ad.

My old neighbour had one of those Bristol overloaders shown in the picture in AJ's post. Was in the 1950's, then Drotts became popular.

Eimco made big overloaders with chains to lift the bucket up on a 'rocker' like their small tunnelling/mine shovels - I've got some sales literature on them somewhere. Base tractor was about D8 size.

Here is another interesting overshot loader….this ones on rubber.

Boy I guess an operator would have a really sore neck by the end of a busy day in the pits. Talk about a blind spot. I do remember the Trojan brand though.

12-11-2006, 08:14 PM
does anyone know if the athey company that made these loaders was the same athey company that later made garbage truck barrel loaders, the type that reach out and grab the barrel and then lift it and dump it into the top of the truck. the garbage company i work for as a mechanic had a few athey garbage trucks years ago, they had a chain and cable lift mechanism that ran on something simular to a forklift track, seems logical it would be the same company but wasnt sure

thank for the pic

There were more than a few brands of overloader built for the D4. Athey is one, LeTourneau is another, and here in Australia, Britstand (British Standard Machinery - who were the Oliver/Cletrac agents) also built one.
I am fairly sure that Armstrong-Holland (IH) built one as well. I don't think too many would have survived .. they were amongst the most disliked items of equipment as far as operators AND mechanics were concerned.
A nightmare to maintain .. and the operator suffered from neck cricks everyday, as well as being regularly showered with spill from the bucket.
I think most operators and mechanics would have been happy to see the last of them go to the scrappers .. :)

The common ones fitted to Cats were Athey, Anderson, Baker, Barber, Heil, Sargent and Teale, can't recall any LeTourneau overshoot or even loaders.

09-17-2008, 09:53 PM
You missed one,:D the Austin. The Austin was build by the Central Ohio Steel Products Co., which was in stalled on Caterpillar Tractors.
I as well, never seen or knew that LeTourneau build an over shot loader.

09-18-2008, 04:06 AM
O.K. - You want proof - OzD can provide it .. :) .. find below, a spec sheet for the LeTourneau Models 40A, 40B, and 60A Overloader. The 40A was designed to fit the D4, HD-5 and TD9W .. the 40B fitted the Fiat 50, 52, 55 and 55L .. and the 60A fitted the A-C HD7W and the DDH Oliver.
The Tournaloader was operated by a standard LeTourneau Power Control Unit (CCU) ..

The front of the spec sheet shows the 1949 version, the rear of the spec sheet has been overlaid with new specs in late 1951. What is curious, is that the standard colour is Persian Orange. Maybe they had an A-C engineer defect to LeTourneau?? .. :D

The LeTourneau Overloader may have been purely a product of the Australian LeTourneau factory at Rydalmere (Sydney) .. but I would be rather surprised if the Australian LeT factory produced an item that wasn't built in the U.S. as well .. :confused:

Even after seeing the picture I still can't recall any overshot LT loaders at the dealers I worked at from the mid thirties till retirement, I can't remember any type of LT loaders on cats.

09-18-2008, 10:26 PM

Thanks for posting the literature on the LeT overshot, is very rare indeed. I have not see one or even hear of one. There was no mention of them ever being built in the United States, in all the literature I have on R.G.LeTourneau not even in the “LeTourneau Legend”. Front end loaders yes, but not a overshot, not even in the patents issued section of the same book. Maybe a Patent infringement, in the United State with the other manufactures is why they is no mention of them in any of the U.S. literature, …..that I have at least. I would like to know if anyone else has any information on them being build here in the United States. But, at an rate thanks for bring this to our attention.

Mickey,send me your address and I will send copy of what I have.My literature is on the Athey overshot loader.Mike Durkin

09-20-2008, 05:30 PM
Mike, A couple came in to Cleveland Bros. in the Wilkes Barre shop where I worked over the years and they were a heavy piece of machinery and not too easy to work on esp. if things had to be disassembled to work on them. I guess they had their place but was pretty clumsy to get around with due to the weight.

Here some pic's from the Austin model 4-C overshot loader.
There were a 2-4-6-8-C models.

And the D7-C natural !!!!!!!!

The pictures show the D4 with the blade, the bucket is at another location. My dad used this to load gravel for the county plus other oilfield and landscaping jobs. Now at 98 he is selling the farm. The D4 ran when he parked it but he hasn't started it for a number of years.

Interesting piece!!! Where is it located and is it for sale?

05-11-2013, 11:32 PM
You sure as hell better be real limber to get in there to start the pony and get the main online. Looks like there is almost no room to do that. :jaw:

05-14-2013, 11:25 PM
Yes, starting it at his age was done by pulling it with a Case 2390. But his earlier years it was always with the pony. It is located at Coronation, Alberta Canada. I would like to see it go to a collector or museum society, that is why I joined the thread.

There is a wonderfull big picture of a D4 and overshot loader in office of Perkins Tractor , in Pasco WA. It were there few years back! ,, should still be there i guess!. pete

05-15-2013, 08:24 AM
Bridged, that is definitely a keeper - there can't be too many of those running around. I'd vote for a collector that regularly exercises them rather than a static display.


05-15-2013, 03:49 PM
I sent you a pm. Thanks

05-26-2013, 12:20 AM
I've taken pictures of the bucket and Tractor Number.
