Gerard,
Have a look a this:
http://telepresence.dmem.strath.ac.uk/jen/lego/ideas.htm
Jennifer Clark always has some excellent ideas (seen her terrific DEMAG
AC50-1 as well?) http://telepresence.dmem.strath.ac.uk/jen/lego/demag_crane.htm
Building a telescopic boom from ordinairy bricks is possible as well, but
the strength is not so good. But Ron Jansen made a fantastic LTM1400 (1:16!!).

Because the boom is so huge and heavy, it wasn't possible to extend it by
motors.
Hint: create a boom which is not too heavy. Else it won't work.
