While I anxiously await the release of Conrads LG1750, I found this information. Please credit Emiel for the real crane pictures, and Conrads' site for the other two. I think the potential problem with the LG1750 is very clear. I'll let the pictures speak for themselves. Wonderful shot of Grohmann Attollo LG1750 upper works:  Comparison shot LR and LG 1750  Conrads' LR1750  Conrads' LG1750  I am not seeing the longer body as is used with the LG1750, better lever arm more boom length can be raised with less counter weight. I hope the model that they haven't released yet has this detail! Mark

It's an extended counter weight tray. It sits on the back of the upper works to put the weight further back. the LR-1750 has em too

I see it too, nice catch. I am sure there will be quiet a few little differences in the model vs the actual machine. It'll be a great model though!

- Chris It's an extended counter weight tray... It's an extra used on the real machine... nothing more then just an extra tray...

What are you trying to say? That the whole uppers on the LG-1750 isn't the same as the LR-1750? OR that the counter weight AND trays are back on the Grhomann and not the sarens? Im lost.. because on the LG-1750 and LR-1750 there's a counter weight tray that attaches to the back of the crane..

Oh geez. We are not talking about the counter weight tray (arm), hence the red "X". The section of the upper that is in the red box is the topic. The two uppers are different. We would like to know more about that (the section that is highlighted by the red box). You can see the difference by looking inside the red box. The section that is highlighted by the red box which is on the LG is not on the LR. The Conrad LG upper looks the same as the LR and therefore, we are thinking, is incorrect. I thought it was obvious.  - Chris

The section that is highlighted by the red box is where the two counter weight trays sit. below is a picture of an LR-1750 .. Has the same "area" in which you are talking about...  Correct?? The "RED BOX" Is covered by the trays when set in normal position. the Grhomann has an extended tray that attaches to the back of the uppers where the Ballast wagon or flying tray would connect. It does NOTHING other then move the Counter weights TO THE BACK OF THE CRANE. Here on this picture.. of a LR-1750 same uppers as the LG the Counter weight trays are sitting in the normal position..   Im not talking about the "COUNTER WEIGHT TRY ARM" It's an EXTENDED COUNTER WEIGHT TRAY THAT ATTCHES TO THE BACK OF THE CRANE. IT DOES NOT USE THE BALLAST WAGON NOR THE FLYING TRAY... It's an attachment for the LG/LR cranes.. Connects ONTO THE BACK of the uppers to PUSH the UPPER WEIGHTS BACK... got it yet?

It's nothing more then a box that connects where the Ballast wagon or suspended tray would connect. Both LR-1750 and LG-1750 have that option. You can't use the Extended tray with the Ballast wagon or the suspended tray.

Does anyone have any more pictures of the extension tray they can post?
It would make it on the list of custom work for my LR1750.

the uppperstructure lenghening piece is an easy way to add momentum by bringing the coounterweight further back,. its a relatively small piece and in certain configuration it can make the use of the derrickboom obsolete.
since LG and Lr1750 upperstructures are of the same system, it exists for both machines of course, but that does not mean that every 1.1 scale owner also owns this special piece for its crane
but while you are at comparing the upperstructures and the model, nobody ever said a word about the derrick boom
usually the LR1750 is operated with 31,5 meter long derrick, but the LG1750 with 42 meter, by adding a 10,5 meter additional derrick boom piece.
this also gives a better angle and positioning for the counterweight thray that has to swing arounnd the extended outriggers (also works with 31,5 meter derrick of course)
i only know Mammoet and felbermayr who own a 10,5 meter piece for their LR1750, but iirc most Lg1750 have it
Conrad did not reproduce this piece of course (among many many other bits unfortunately)
i custom built it for my Felbermayr LR1750, pics soon
to me its sad that Conrad did not pursue the offerings of the LG/LR1750 modular system more
they got 2 1/2 years of delay for bringing the LG1750 to the market, i also remember the Lr1750 itself was also late (which Conrad model isn´t?)
they did not make:
free hanging counterweight tray (comes with the LG, probably not sold as separate i´d bet), only availabel as brass aftermarket piece
upperstructure lenghening piece
pedestal outriggers (same as above, 200 euros extra brass piece)
conic boom reduction piece to go from heavy to light boom sytem for long main boom configurations
extra 10,5 meter derrick boom piece
heavy vessel lifter boom head
and i am not even talking about all the special equipment like SLK boom system or the frame to hang a 100tonner as counterweight
did i mention the track pads?

Christian, you didn`t mention the fact that the LR1750 model has the wrong size track pads.
correct lenght but not the correct width, they are too wide.
Conrad have just taken the easy way out and used the track pads from the CC8800.

Chris - Thanks you for those pics! Design on the counterweight extensions will begin this weekend.
Christian - any photos of the heavy vessel lifter boom head available in your collection?
Damn..now I may have to buy another LR1750 for all the mods I want to do.
