(...) the lateral bracing is really important, do as much as you can to brace it, it is one of the few problems with my boom, the mast will shift causing the boom to lean, then it falls, and youll probobly have to fix more than just the boom. and (...)

Hi Ross! (...) yes, all beams booms are interesting, but not necessarily useful. c (22 years ago, 1-Apr-03, to lugnet.technic, lugnet.modelteam)

(...) The main problem with an all axle boom is that it can take almost no tension. This means for a long boom it bends under its own weight when horizontal. ROSCO (22 years ago, 1-Apr-03, to lugnet.technic, lugnet.modelteam)

It really looks terrific! It's definately a competitor of Ron Jansen: (URL) hasn't built boom sections yet because of lack of time. It progresses very slowly. Is Chris' crane built on scale?

(...) The ballast rigg is supported by wheels so than can bear heavy weights. (URL) suppose you use 20 x 30 technic wheels? Would it be possible to raise the ballast rigg or may the crane be unbalanced then? Big challange!! Dennis Bosman (22 years ago, 1-Apr-03, to lugnet.technic, lugnet.modelteam)
