In Canada, JRT will engineer a controller to work with a wide variety of existing equipment, and build a relay logic controller for basic, handicap accessible lifts.

Is there an American equivalent? It seems most companies want to install proprietary circuitry, leveling systems and rip out the whole unit and replace it as a package.

If you know any relay logic controller mfgs that will create a mod controller for a platform lift, please let me know if that exists!
