Interesting. First, what you have is a trolley; like a trolley car that
goes down 2 tracks. The load is above the 2 tracks. A tram OTOH is a single
line where the load is suspended under the tramline.
I use the tram method about 90% of the time because it's much less
complicated than a trolley system, is easier and faster to rig, and does a
of getting yagis up and down. I even use it to get HF yagis - including 40M
beams - in trees.
For me there is too much friction and rigging involved with a trolley
system but it looks like yours works for you.
