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?
