Hi, Jeff.

Does your theatre have flying rigging? If so, could you re-purpose one of the
line sets to operate the dolly? It would require a qualified rigger to tie off
the existing pipe, rig a turn block at the right location and build the custom
cabling. It might also require sistering two adjacent sets, to allow easy
operation both empty and with MP on the dolly.
