An elementary school principal has inspired the University of Wisconsin-Madison to create a new wheelchair lift that could help make more places wheelchair accessible.
The invention process began three years ago when the principal at Emerson Elementary School in Madison, Karen Kepler, told a school donor her biggest wish was for her building to become accessible to everyone. All four entrances had stairs.
The donor went to the University of Wisconsin-Madison for help.
Engineering professor Jay Martin, his students and others came up with the Funicular. It's a platform that uses rollers and a modified chain hoist. It allows users to move up the stairway by turning their wheels on the rollers.
