This week one video from a Tower Crane with Luffing Boom, by Mike Hatton (Parax).
This is a crane with very generous dimensions and noticeable structure rigidity (see how easily, it lifts an '8294, Excavator').

It is always good to have a face to put on a name, Mike.
You can find more images from this crane, at Mike's BS folder.
For a detailed description about the design process and how the required stiffness ws accomplished for the studless lattice, read Mike's Tower Crane presentation at LUGNET.
