Hi Beat,
As I've already said to you in my e-mail your crane is fantastic. Well
detailed, my compliments! You did a good job by making such a huge crane!
Are the 9V motors strong enough? I red you use two 9V motors for the
revolution of the superstructure. Does is shock? Former I had some problems
with that and actually still have with my CX700 Hitachi. But that's due to
the top heavy leader of this machine. My LG1550 did very well, but the drums
weren't fine to me.
I saw on Brickshelf you use those 40z gears for the drums. If you hold the
ropes tight, don't you have problems yours large gears are moving to the
side? Esspecially when you put a heavy lift in the hook. But it looks very
good, five drums, that's a lot!
You boom seams to be very light. How much time do you need to build the
crane up? Esspecially the ropes needs much attention I guess ... (I speak
from experience) I think Thomas has this problem as well ...
I hope to see this masterpiece once in real life!

| (...) The 9V motors are strong enough. Sometimes it shocks a bit, when the weight is not well distributed (means that I either have too much or too less counterweight). The crane is able to do 0 to 1.2 revolutions per minute. When studying the spec (...) (23 years ago, 21-Nov-01, to lugnet.modelteam)
