[TowerTalk] Any thoughts on spider-beams?

[EZ Rhino]

Sure it can!  We assemble the spiderbeam on the ground, and I've got video of my buddy lifting a Spiderbeam with one hand onto the mast pipe at the top of a nested Spidermast, about 8 feet off the ground, while standing on a ladder.  They are very lightweight.  However, the cross booms are what, 10 meters across?  So that's about a 15 foot radius, which means putting it on a mast if the tower/mast are tipped over horizontal, yeah that is a problem!  A tilt-plate type gadget would be needed.

Why is this?  Is it related to having a boom truss?
