Automating manual 9 station target turner system

Hi all,
Our club is looking into auyomating our manual 9 station target turner system. we currently use stell cable and pulleys along with a metal pull bar to turn targests for BE shooting.
Does anyone know of a company the provides an electric system to hook up to the cables/pully system? Any DIY solutions would also be appreciated.
Thx

I've automated or built turning target systems for two outdoor ranges and one indoor range, and helped two other outdoor ranges convert thiers. All run with pneumatic cylinders. Two I built are/were connected to a compressor, the third is powered off of a SCUBA tank as there's no close power. It's not hard to do, but you there are a few tricks to consider, like making sure the rotation doesn't go "over center". Pm me if interested and we can start a conversation. With volunteer labor, the largest costs will be the cylinder and controller. The first one I built used timing relays and a manual starter button. The second two used target timers controll boxes, more expensive, buy WAY easier for both builder/installer and range officer.

Thx. I'll get pics and send tkem to you.
