Really enjoyed this excellent video. Very well done! I have been a fan of the big Koehring excavators for many years. I remember back in the mid-1980’s watching a 1266d dig a 40 foot deep pit in the NJ meadowlands area. Work was related to a waste transfer station.The Koehring was equipped with approximately an 8 cubic yard bucket and loaded a fleet of Euclid R-50 haul trucks and a couple of Cat 35 toners.The thing that amazed me was the extreme reach capability with such a large bucket.Had to be about sixty feet from the center pin to the bucket @ max. reach.As you know the Koehring 1266d had an operating weight of over 130 tons.That Koehring 1266d was a very impressive piece of American made heavy equipment!
I grew up with my dad working for a geotechnical contracting company that operated a variety of modified koehrings to dig trenches of abnormal depth for an excavator. Nowadays there are a few production machines for it, but they top out at around 50 foot depth, and lack the weight and footprint to heavily modify. Those modified koehrings would do 80+ ft.
Wow, you've all the right stuff in your video gallery! Excellent.
+Benjamin Beytekin Glad you liked it! Thanks
I operated one of these for quite a few years , they were great powerful machines , thanks for sharing this video !
Back in the day a contractor doing sewer canal work used one of these. Koehring definitely are impressive / one of a kind excavators.
would you happen to know how long it has been since it ran?
a great walk around of that Monster.
Awesome video! Love the Koehrings, we still use a friends 455 and 466D. A quarry nearby my house has a 1266D. A real monster.
+J Gibson I'd love to film a 1266! Haven't found one yet though. Thanks
+PAmining I remember my dad took me to see a 1266 when I was about 10. I wanted to run it.
awesome thanks for sharing
Awesome old excavators.
Fantastic work!! as allways justin!
+CAT POWER (ALLDAY) Glad you liked it! Thanks
klasse video,s..top.
Nice video my dad had a C 366
any chance of doing a documentary of the case drott crane in the background?
My God that thing would scream with a V12 2stroke Detroit...i would have loved to hear it running
This was my favorite excavator when I was a kid
Nice documentary!!! It will be great if you make a doc about the CAT 350 or the 375
+Bruno Carneiro Thanks, and I will be doing the 375 in the future.
A gravel pit down the road from me has a 1266 with twin Cummins in it. They used it for stripping clay and that thing was a Hoss. It is mechanically sound but the undercarriage is shot and it kept throwing tracks. Finally about 2 years ago it threw one and they just limped it over the the side and now the poor old girl is just sitting there like a beached whale.
+Oliver66FarmBoy Cool. I sure would love to see a 1266.
Very cool. When was this one put out of commission?
Great videos. Keep them coming.
+TheMrKeys No this unit was in operational condition, just not being used at the time
I noticed 2 cylinders under the engine with pulleys and cables attached to the rod ends. Are they for counterweight removal/ installation?
+legitasspirate Yes they are
I wonder if when these brands get acquired multiple times, if the current owners make sure that parts are readily available and for how long...
8:28 also showing the two hydraulic cylinders that (I assume) lower and lift the counterweight?
+YensR That is correct
That machine is as old as me... and yet it's in better shape.
BTW, different track tensions or just less shoes on the right hand side crawler track?
+NeAZ Looks like it has a bad track adjuster seal
There was a nitrogen cyl. Behind the front idler, that provided the movement of the idler, track adjusting was by shims between the idler and the yoke. A very poor system, defiantly one of the weak points on the machine. Very common for the nitrogen to leak from the cyl and have a loose track, that’s what’s wrong with this one.
Great machine! Thanks for the video. Is that machine still in service today?
+lidsman2221 Yes, I believe it was sold and relocated to a different site.
What would be the benefit of having the two engines vs a single engine? Seems like it would be double the maintenance and cost running two vs one larger engine.
+Blake Budney Twin engine machines were normally designed to accommodate for the required output to run the excavator that wasn't available at the time from a single engine. Other reasons twin engine designs were used was to help reduce overall operational expenses. For example, if an excavator has two V-8's and one needs replacement, the cost to replace a single V-8 is way cheaper than replacing a single V-16 in the same class excavator. Make sense? Today, twin engine designs are still commonly used in larger mining class excavators but never in an excavator of this size. A lot of operators do frown upon the twin engine design, often calling it "double trouble" because of the double number of components to replace.
Have you had any luck getting any video of it digging? Kinda looks like it's been sitting for a long time great video though.
+bert26a I have come across many old Koehrings in my travels, but never have gotten to see one work yet
How much does this. Weight ??
We rented a 1066E from a local company back in 1994, once we got everything fixed that it ran good it was fun to operate. If I remember correctly it had a air system on it for the controls, it also had a free swing kinda like a dragline.
+Schneiderexc Yes, the older Koehrings were air over hydraulic. A very different feel to run one of those machines!
+PAmining yeah that air was hard cause it was all or nothing. No sit it down, easy. The C366 had two levers and 4 foot pedals. Two levers on each side of you was for the tracks.
nice to see clean hands, does koehring also make coffee makers.
+memyselfand ifarmer thats kuerig youre thinkin of lol
Very little difference between an 1166E and a 1066E, main frames were the same, booms were different, the 1066 had boosted hoist only, the 1166 had boosted stick as well and more weight in the C/W… The E models ended in about 1981 or 2 and was replaced by the 20,000 series that had improvements over the E models…
What Modern day machine is this comparable to size wise?
+Boomer617 The 1166 was comparable to the Cat 385/Komatsu PC800 class
+PAmining thats what I thought thanks!
any idea why american producers put cabin on the right side ???? P&H, oehring, Bucyrus-Erie, American, Warner Swasey, Hopto , early John Deere
Where do you find all these machines.
Is this bad boy still alive or it is left there to rot and wait to be scraped? It looks very good.
+Selmir Ikanovic It was sold and relocated to a new jobsite
nickyc2027 that was my dad's machine
Always wondered why the old excavators have the cab on the opposite side
The reason for right handed cabs is because that's how Koehring's old cable excavators were setup. Koehring (along with other manufactures), kept the operators station on the same side when they developed hydraulic excavators to not confuse operators who were accustomed to a right handed cab
Why did they put the operator's cab on the right side like a dragline?
+Matthew Hoag It was just the design of the machine. No different than why most Bucyrus-Erie cable excavators had right-hand cabs and Marion was left-hand.
