This was an old bag kite and we were working out ways to speed things up.
We had triple block mounted on the front beam and a free moving triple on the tramp.
The uphaul went from the head of the kite, around the block on the mast above the hounds, down to a turn block on the Spi pole and thru a cleat on the front beam (as per normal).
Then the uphaul went to the free floating triple block on the tramp then to the triple on the front beam and back and forth. You now have the uphaul wound around the block system.
From the free floating block on the tramp we then ran a sheet line from the back of this block to a turn block on the back beam - we now have a 1:6 uphaul.
For each inch the free floating block moves(via sheet line on the back and turn block on the back beam), 6 inches of uphaul is pulled.
We had a seperate downhaul (Called a crew) who re-stuffed it in the bag.
We also ran some shock cord to the back beam so that the uphaul went around floating block correctly.
So when the kite was fully down and bagged, we had the floating triple near the front beam, when the kite was up, we had the floating triple at the back beam and about 2m of (1:6) uphaul floating around the tramp.
It worked very well as the kite went up very quickly and if need be you still had 1:1 for the last little bit as the 1:6 was after the cleat.
Drops were also fine as (again) if need be we still had 1:1.
If using a pole mounted bag, you would need either a seperate downhaul or somesort of pump system.
