 | | My Latest MOC: 1.4m Boom Crane —Jeff Elliott
|
| | | Hi all, Thought I'd post a photo of my latest creation, a technic boom crane. (URL) genesis of this MOC is that I'm building a Lego cubicle divider at work. Naturally, for such a large scale project, a large crane is needed (duh! :D) So I set about (...) (24 years ago, 8-Feb-01, to lugnet.build, lugnet.technic)

| | | | | Very impressive, Jeff. Looks like you did a very good job of creating all of the structures required of the real thing. I like the use of axles for the cross bracing of the tower. That should be effective with the friction of so many connectors. If (...) (24 years ago, 8-Feb-01, to lugnet.build, lugnet.technic)

| | | | | | Thanks, Bob, I've taken several more pics of the crane, and uploaded them to Brickshelf. (URL) comments: The turntable is enclosed, since it was neccessary to provide tiles for the crane body to slide on. The base of the table is gray; the rotating (...)

| | | | | | | The additional pictures are interesting. I like the turntable drive. You sure packed that into a small area. Very clever! -- Bob Fay California, USA rfay@we.mediaone.net (URL) (24 years ago, 9-Feb-01, to lugnet.build, lugnet.technic)

| | | | | | (...) Have you noticed the shaft with the worm gear turning unevenly (jumping)? If so it can be reduced by rotation one of the u-joints 90 deg relative to the other (so the slots line up, rather than 90 deg offset). This probably wouldn't affect the (...)

As for height, each of my tower sections uses a lot of pieces, so even though I'd love to challenge his 4.2m, I don't (...) (24 years ago, 9-Feb-01, to lugnet.build, lugnet.technic)
