After few years of hard work I was able afford to upgrade my laser and video projectors to more powerful ones. My work consists of moving the equipment to a venue, installing them on my tripods and running my custom made laser and video mapping shows.
Since my old laser projectors (1W) and video projectors (5000 lumen) were not so heavy, around 30 lbs with their frames, I used ordinary speaker tripods for each which could handle around 180 lbs and made custom welded adapters and frames for the projectors. I attached the projector frames to the tripods on the ground and 2 of us could then raise the tripod, one holding the bottom side of the tripod one the attached frame. Then 2 people could adjust the height of the tripod in its standing position. All the parts were more than strong enough to handle the weights.
But now I've got 70 lbs projectors compared to the previous 30 lbs and they are much more expensive as well to afford damaging them, plus the weight is too much to rely on one tripod in my opinion even if we (there's still two of us) could install such heavy equipment.
So I'm thinking of getting a better, stronger and easier to use truss/tripod system.
I'm currently considering a “crank-up truss system” for two main reasons:
1) there's two tripods instead of one, more feet means more stability
2) more importantly, the cranking system will allow to attach the projector frames or in case of laser the laser handle to the truss at a low level then raise the tripods with the cranks. No need to attach the equipment on the ground and raising the whole tripod from laying position to standing which I think is a very bad idea for these weights.

Anyone used these kind of truss systems and can give their opinion?
I know there are these square and triangle aluminum or steel arch shaped truss systems used for stage lighting and audio equipment but those are still a bit overkill for our job and our small business and also many venues we work with are too small and wouldn't want something taking up that much space just for 1-3 projectors.
