How does the drive mechanism work and are there different methods?
Drive mechanisms use an electric motor and gearbox to extend and retract the panels of curtain material in a system. They solve the problem of translating the rotary motion of the motor and gearbox into the linear motion needed to move the curtain panels. There are three basic methods. The push-pull drive can be used to move truss-to-truss systems only. Both the cable/drum, and the chain and cable drives can be used for both gutter-to-gutter and truss-to-truss.
