Good Afternoon.

I have finally gotten around to posting the completion photos of my Liebherr
LR-1750 (fomrer LR-1600).  The photos show the crane set up with the heavy main
boom, the superlift with counterweight tray, and a luffing jib.  The overall
height of this crane shown is only 14', but it proved to be more than stable
enough to add more boom.  Even with a 15 mph wind blowing, the crane was hardly
rocking at all.  I plan to make some more boom, or even steal some of the boom
from my LR-11200 to try to test the maximum height that I can get out of this
model.  The pictures are at the following link:

Take a look and feel free to give any compliments or criticisims.

Some specs are as follows:

Main Boom = 108"
Luffing Jib = 60"
Counterweights = 30lbs
Motors = 6
Time = at least 40 hours
Parts = ???

Thanks for you time

-Alvin.

(...) Hello Alvin, Excellent work, this is a very impressive model! I really like the red & white color scheme on the luffing jib and the huge crawlers. I'm not sure if it comes apart easily but I would be interested to see pictures of the how the (...) (19 years ago, 1-Nov-05, to lugnet.technic)
