At the request of Finn, engineers from Hydrotech, Cincinnati, a fluid power distributor, began exploring the possibilities available for mechanically locking the cylinder rods in place automatically without having to use the prop rod. They also wanted to ensure that the gate would not move in the event of hydraulic pressure loss. Their search ended with Advanced Machine & Engineering (AME), Rockford Ill., which manufactures the Amlok mechanical rod lock.
