Unlike any other dumbwaiter, the Ascent® uses a special drive train and track system that makes it very easy to install and economical to own. Typical dumbwaiters are built like mini-elevators with complex pulley systems, guide rails and traveling control cables. The Ascent comes from the factory with the entire drive system pre-installed on the underside of the car, and the car chassis/trolley system pre-installed on a section of the track. Installation isn't much more complicated than connecting sections of track, securing the drive cable to the header, and routhing the wires to the control buttons and door interlocks. In many cases, a full day of installation time can be cut from the process. That's real savings!
