(...) This makes sense since the even length axles are now black and the odd length ones are now light grey. Axle pins have also gone to a single color, tan if I recall. -Orion (20 years ago, 17-Jan-05, to lugnet.color, lugnet.parts, lugnet.technic)

Salut Didier, (...) I think they are using different colors for different pins to make building easier, so younger children can do it. And blue for the half-pin seems to be the standard now. Jürgen (20 years ago, 17-Jan-05, to lugnet.color, lugnet.parts, lugnet.technic)

Hi, Sorry if this have ever been discussed.

Dennis Bosman- I have a request of you. Do you ever keep in contact with your colleague Ron Jansen (the builder of the Van Seumeren Liebherr LTM 1400)? Do you know if he has a computer? If he does, would you mind giving me his email address? Thanks. (20 years ago, 17-Jan-05, to lugnet.technic)

Ross- When you were building your Demag CC 8800, did you get a set of blueprints from the Terex Demag company there? If so, did you send an email requesting blueprints? Thanks. (20 years ago, 17-Jan-05, to lugnet.technic)

I came across a design I did 8 months back. The way I have this drawing is that one motor operates the first section, and right beside the motor is a cable that retracts and extends the rest of the boom. I will post pics of it as soon as possible. (20 years ago, 17-Jan-05, to lugnet.technic)

Is this why on those big cranes (Demag AC 500) there are a small set of wisible pulleys on the ouraaise left side of the boom? Thanks. Thanks for the drawing. Very helpful! Keep on building cranes! (20 years ago, 17-Jan-05, to lugnet.technic)
