| | | Guys- I have successfully saved my files to brickshelf. Apparently when I tried to save them earlier, the names had spaces in them (a big no-no when saving files onto brickshelf). (20 years ago, 27-Jul-04, to lugnet.technic)

| | | | (...) Exellent! Looks like this is them (URL) you planning to do a 5 section boom? That'll make it at least 10 wide, probably 12, and very heavy! What technique are you planning to lift the boom? Incidentally I figured out a way to get a 4 section (...) (20 years ago, 27-Jul-04, to lugnet.technic)

| | | | | Thanks for that compliment Rosco. And in answer to your question, yes I will be planning a 5-section boom for this crane. I am doing some rough sketches of how to work it out right now (I am using Jennifer Clark's idea for the sectioned boom). Also, (...) (20 years ago, 27-Jul-04, to lugnet.technic)

| | | | | | (...) Yummy. One thing I'd like to look at one day is the possibility of using a leadscrew arrangement and locks inside the boom like most cranes use these days, so that each section can be extended individually. But that is probably a pipe-dream... (...) (20 years ago, 28-Jul-04, to lugnet.technic)

| | | | | | (...) I really like the system you mention, it is a really elegant solution. It also appears to allow more telescoping sections, presumably to due not having additional complexity with each added section, unlike a cable driven section, and perhaps (...)

| | | | | | (...) From what I saw on the AC100 (URL) the operator just dialed in the length they wanted, and the pooter chose the position of each section (in that case it was fully extended anyway so not a difficult calculation). Each section had (IIRC) 3 (...) (20 years ago, 29-Jul-04, to lugnet.technic)

| | | | (...) Vineet I saw the chassis of your crane... looks great (and huge!). I'm just waiting to see the rest of the crane. Keep on working. And Rosco, can you show us please how did you build that 4-section boom? Maybe a 5-section boom can be built (...) (20 years ago, 27-Jul-04, to lugnet.technic, FTX)
