Hello Crane fans As Dennis Bosman already announced in his "Modelteam Newsletter" of November 15, I built a model of a crawler crane. It is a Liebherr LR 11200, the biggest machine of this type, Liebherr builds. In reality, there are only two of (...) (23 years ago, 20-Nov-01, to lugnet.modelteam) !

(...) Excellent work, Beat. Yet again, you've impressed us with another great model. Your boom construction is quite unique. Thanks for the close-up pictures, I'm able to see how you built it now. (URL) your beams upside down and using 1x plates for (...) (23 years ago, 20-Nov-01, to lugnet.modelteam, lugnet.technic)

(...) The plates are the main member. You're right, it is a really strong construction. There are several crossmembers between the two parts of the track frame. One of them is the motor itself, and the other ones are also the housing of the (...) (23 years ago, 20-Nov-01, to lugnet.modelteam)

I did it on the body of my crawler crane: (URL) then built several "sample" bridges to display this concept: (URL)I made (...) (23 years ago, 20-Nov-01, to lugnet.modelteam)

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 (...) (23 years ago, 20-Nov-01, to lugnet.modelteam)

Well Thomas, when do you start building a new crane?!?! It's true the boom is much lighter with Beat's construction. But I think it isn't as stiff as when you use technic beams as diagonals. It could have a torsion, but Beat's boom isn't very wide (...) (23 years ago, 20-Nov-01, to lugnet.modelteam)

Hi Beat and Thomas, (...) other. Everyone has it's own way of building. We can solve problems together. Looks good those plates on the sides. If you have lack of bricks, it's a good solution. Although I prefer bricks, but you ran out very fast. (...) (23 years ago, 20-Nov-01, to lugnet.modelteam)

Beat, Amazing, it looks great. The pictures do a great job of showing of the complexity of the model. How did you get the blueprints? I am working on a Liebherr crane at the moment and would love the additional help the blueprints would provide, all (...) (23 years ago, 21-Nov-01, to lugnet.modelteam)

(...) Yes, I used a Technic turntable, mounted upside down. This way the gear of the turntable is fixed to the chassis and therefore the motors for the revolution can be placed in the upper structure - like in real. I didn't use a threaded axle. It (...)

Do you have enough room for a drive for the revolution in the superstructure? Because you don't need the room in the undercarriage, I should say that I put drive into that section. It's not like the real crane, but I mostimes need the space in the (...) (23 years ago, 21-Nov-01, to lugnet.modelteam)

(...) Currently I have enough space in the upperstructure. But this will change with the second edition. I studied the blueprints and realized that I have to move the five winches closer to the turntable, which means that there won't be enough space (...) (23 years ago, 21-Nov-01, to lugnet.modelteam)

(...) 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)

Hi Beat, About the lifting capacity. Seen this crane? (URL) guy claims it can lift more than 10 kg. I've seen this crane several times, but he huses to many non-LEGO components. The crane is also much to heavy, it almost collapst for several times (...) (23 years ago, 21-Nov-01, to lugnet.modelteam)

(...) Yes, be very careful! The ideal condition that a crane builder wants is that upon maximum load, the crane starts to tip over rather than break. When the crane starts to tip, you can immediately stop the lift and all is saved. However, if (...) (23 years ago, 21-Nov-01, to lugnet.modelteam, lugnet.technic)
