Thanks to all for the info. Hey Michael, I'll take one of everything!

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.
Ray... I never sat down and measured the Conrad 1750 pads, but according to the Liebherr web site they come in two sizes - 4'11" and 6'7" wide (I presume.) I can also post drawings, photos and sworn affidavits if this is not clear to everyone. God forbid, we go through another fiasco...

As for the tracks yeah... Just another cut corner by conrad Too bad we don't know anybody that could mill 10,000 track pads... *cough cough michael*

Lets get this quite clear, I think your confusing your widths and lengths.
when measureing any component in engineering terms, the longest dimension is the LENGHT the shortest is the WIDTH. (unless your measureing in 3 dimensions, but I won`t go into that).
Your quite right in saying That the Liebherr spec sheets quote 2 sizes, 1.5m and 2m.
If you look at the spec sheet you will see there are 69 track pads, on the Conrad model there are only 44 track pads. they are much wider.
I think this short cut totally changes the look of this model.
Ray...

this is what a 1750 system upperstructure extension piece looks like up close. no difference between LG or LR, its 100% the same system just brings your whole counterweight 2m30 further back. you bolt this to the end of your regular 1750 upperstructure and hang the cw holders to the side of it, using the rear hooks of the upperstructure as new front hooks and using the hooks on this said piece. done as you can see on the side, it even has a cupholder, for american market (just kidding)

Ray... I agree 100%. With all of the upgrade parts offered by YCC, I can't believe that the proper track pads were not the first ones to be made. Christian, thanks for the nice picture of the part. Funny how things like that turn up in the middle of a field - kind of like a crop circle.

there is a way to fit the LR1750 with correct sized track pads... just is "a bit" of work and patience...

Ray... Ahhhhh, I see (said the blind man!) Yes, thank you for the clarification. The difference between length and width always threw me in school...

There is a degree of criticism of Conrad in this thread which I can understand. However in their defence I think the 'corner cutting' with regard to the track pads is an issue that I am sure Liebherr signed off on. No doubt the LR1750 was developed within a budget and to hit an anticipated sales price. This model would have progressed with Conrad and Liebherr working together. This issue facing Conrad and it has been there for a few years now is how do they produce models which can compete with Chinese made ones? On the labour cost they can't compete which is why Chinese models from TWH etc have a lot more of the labour intensive detail. Conrad remain very good at engineering their models with few scaling errors and well made pieces that fit on the whole. At all times they have to satisfy the commissioning OEMs. Models developed at their own risk is another subject, and it must be a hard balance for them between details / features and price bearing in mind their German-based costs.

^^^ Yes, very well said. These "supersize" models have to be a bit risky for any manufacturer - any sort of economic downturn and the market is pretty much toast. When I initially started a small collection in the late '80s, NOTHING of this size was readily available. The big cranes were almost wholly hydraulics, and rather poorly detailed at that. A few smaller lattice boom crawlers could be purchased, but they were quite pricy by the standards of the day. At that time, I would NEVER have dreamed of shelling out $500+ for a single model - even if they were available.
I wouldn't be surprised if Conrad found 69 pad tracks wouldn't rotate properly with the overall weight of the crane and opted for simpler engineering with a 44 pad unit. Or perhaps it was just a cost saving measure - no analysis done.
