Moving a plow blade with actuators

Hi all

I was wondering if anyone out there had a program that could move 2 actuators at the same time in opposite directions, meaning one screw in while the other goes out.

To would be used to swing a blade left and right, one actuator pushes while the other pulls, and once stop the pushing load on the blade would be shared by both statically.

Any suggestions on how this could be done, I think it's possible??

Thanks for the advice and help

You could do it mechanically. Use a lead screw with one half right-hand threaded and the other half left-hand threaded. Then a single drive motor will provide a balanced drive in opposite directions.

Something like one of these :
