Abstract
A piston-type passenger conveying system includes at least three cabs to move between two floors. A control moves the cabs such that a cab is always waiting at each of said floors, and another cab is always moving to a floor. In this way, the system achieves the passenger flow benefits of an escalator with the inherent benefits of an elevator system.
