Hi sifu, I would like to change my gate (subsale house that already got autogate motor). Is it possible to just change the gate and keep the motor?

My question is, how do I know whether the current autogate motor is still good? Or is it strong enough to support new door that might be heavier than old door?

*two side swing open close gate by the way. Plan to get new stainless steel gate due to budget constraints cannot get aluminium.
