Additional Photos of the Playground Lifting Device
and the Student Inventors

Photos by Will Kirk

Image A: The device created by Christian Callaghan, Denice Koh and Nate Kruis can lift a handicapped child more than 3 feet off the ground to access playground equipment.

Image B: Christian Callaghan lowers a side panel of the lifting compartment, which allows easy entry for a child with limited mobility; co-inventors Denice Koh and Nate Kruis look on.

Image C: Four wheels mounted on the rear of the lifting device allow it to be tilted like an appliance dolly and moved easily to a new location.

Image D: For safety, the controller for the lifting device can be stored inside a locking box mounted on the machine.

Image E: The lifting device is operated by a control box equipped with large, easy-to-use switches.

Image F: Air pressure from this scuba tank activates a pneumatic piston and pulley system that gently moves the passenger compartment up and down.
